China Aluminum Sheet Metal Fabrication | Custom Aluminum Parts
Aluminum sheet metal fabrication in China gives engineers and procurement teams access to precision-cut, formed, welded, and finished aluminum parts. You can get all these at cost structures that domestic suppliers in the US or Europe rarely match.
XTJ CNC has specialized in precision China aluminum sheet metal fabrication for over 20 years. We understand that OEM engineers, product designers, and global sourcing teams require more than just a standard vendor; our facility is built to support your entire product lifecycle.
Custom Aluminum Sheet Metal Parts Built to Spec, Delivered in Days
We manufacture custom aluminum sheet metal fabricated parts matched exactly to your specifications. We offer high-quality service by managing the entire fabrication sequence under one roof. Rather than outsourcing critical manufacturing steps, our in-house technicians handle the complete progression of your project. We maintain strict quality oversight at every phase, which allows us to reliably meet tight delivery windows.
Aluminum’s combination of low weight, machinability, and corrosion resistance makes it one of the most requested materials in precision sheet metal work. Getting the most from it requires the right alloy selection, the right bend radii, and the right finishing sequence. Our engineering team handles all of this before the first cut.
Sourcing aluminum sheet metal fabrication from China is a capability and cost decision. China-based fabrication providers operate at scale. That includes running advanced fiber laser systems, CNC press brakes, and robotic TIG welding cells that many regional shops can’t match.
Engineers managing tight tolerances, cosmetically sensitive anodized surfaces, or fast prototype cycles can benefit from the right Chinese partner. Such partnerships compress development timelines and reduces per-part cost.
As the global sheet metal fabrication market continues to expand, there’s more demand for lightweight aluminum components across various sectors. That growth makes it increasingly important to work with a certified, experienced aluminum sheet metal fabrication partner.
At XTJ CNC, we cover the full aluminum sheet metal fabrication process sequence, from raw sheet to inspected, finished part.
Fiber Laser Cutting
We cut aluminum sheet with fiber laser systems that deliver clean edges without the heat-affected zones associated with COâ cutting. Cut tolerances hold to Âą0.1 mm on qualifying features. Sheet thicknesses from 0.5 mm to 20 mm are supported across common alloy grades.
CNC Bending
Our CNC press brakes maintain angular tolerances to ¹0.5°, critical for enclosures and structural brackets where mating faces must align. Offline bend sequence programming minimizes springback. We work with sheet thicknesses up to 12 mm depending on alloy grade and required bend radius.
TIG and MIG Welding
Aluminum welding requires shielding gas, cleanliness, and thermal control that differ significantly from mild steel. Weld quality follows AWS D1.2 structural welding standards for aluminum, with full material and process traceability. Our team performs TIG welding for structural aluminum assemblies, enclosures, and weldments.
Surface Finishing
Aluminum supports a wider finishing range than most metals. Options include Type II and Type III hard anodizing, powder coating, chromate conversion (Alodine), bead blasting, brushing, and deburring.
Rapid Prototyping
We accelerate your development cycles by ensuring that prototype aluminum sheet metal orders ship in just three to five days. We also support design iteration with fast-turnaround aluminum prototyping alongside our CNC machining and 3D printing services for early-stage validation.
What Aluminum Alloys are Available for Fabrication?
Not all aluminum alloys behave the same way under bending, welding, or anodizing. Alloy selection affects formability, strength, corrosion resistance, and surface finish quality. We work with the following grades as standard:
| Alloy | Key Properties | Common Applications |
|---|---|---|
| 5052-H32 | Excellent formability, good weldability, strong corrosion resistance | Enclosures, panels, marine components, fuel tanks |
| 6061-T6 | High strength, machinability, moderate weldability | Structural brackets, aerospace frames, heat sinks |
| 3003-H14 | High ductility, low cost, easy to form and weld | HVAC components, storage tanks, general sheet work |
| 6063-T5 | Smooth surface, good anodize response | Architectural parts, cosmetic enclosures, trim panels |
| 1100-H14 | Highest formability, excellent corrosion resistance, low strength | Deep-drawn parts, chemical equipment, nameplates |
If your application requires a grade outside this list, contact our engineering team. We maintain relationships with multiple aluminum sheet suppliers and can source to specification where needed.
XTJ CNC delivers custom aluminum sheet metal fabricated parts for demanding industries. Because each sector operates under distinct tolerance thresholds, material specifications, and documentation standards, our facility is equipped to strictly adhere to those individual compliance metrics.
Aerospace
We precision-fabricate critical elements for the aerospace sector, including structural brackets, control surface components, and robust enclosures. To meet these demands, we source aerospace-grade alloys such as 5052 and 6061, and we secure every shipment with Coordinate Measuring Machine (CMM) documentation.
Automotive and EV
Automotive and EV programs increasingly specify aluminum for body reinforcements, battery enclosures, and thermal management components, where weight reduction directly affects range and performance. We fabricate these parts from 5052 and 6061 aluminum, ensuring dimensional repeatability. Our operations run under the IATF 16949 compliant process, with First Article Inspection reports and GD&T-annotated CMM outputs available on request.
Medical and Healthcare
Medical device enclosures, instrument frames, and equipment panels demand burr-free edges, tight dimensional control, and surfaces that survive sterilization without degrading. Aluminum is the right material for many of these applications – lightweight, corrosion-resistant, and compatible with anodizing and passivation finishes that meet cleanroom and hygiene requirements. Our quality processes are aligned to ISO 13485 requirements, with full material traceability from raw sheet to finished part.
Electronics and Consumer Products
Aluminum is the default material for consumer electronics enclosures, heat sinks, and chassis â lightweight, thermally conductive, and capable of a cosmetically finished surface that plastics can’t match. We fabricate these parts with in-house Type II anodizing, hard anodizing, and brushing. Our three-to-five-day lead times let your R&D team validate fit, thermal clearances, and finish quality before committing to production tooling.
Industrial Equipment
Industrial equipment prototypes often involve heavier aluminum gauges, multi-part weldments, and structural assemblies that need to function together before a production run is approved. We fabricate these components using MIG and TIG welding processes that follow AWS D1.2 standards. Where structural loads demand higher strength, we recommend 6061-T6 aluminium.
Partnering with XTJ CNC for your custom aluminum fabrication needs directly optimizes your production schedules and guarantees high-quality output.
Faster Time to Market
We actively compress your product development cycles by providing rapid, three-to-five-day lead times for prototype delivery and conducting Design for Manufacturability (DFM) reviews.
Lower Per-Part Cost
Our China-based fabrication facility grants your procurement team direct access to precision CNC bending technologies at a fraction of the cost typically quoted by equivalent Western suppliers. This economic advantage is achieved without ever compromising on your strict geometric tolerances or the final cosmetic finish quality.
Alloy-Specific Process Knowledge
Aluminum behaves differently from steel at every stage of fabrication. We apply alloy-specific bend allowances, weld parameters, and anodizing prep procedures as standard, not as an afterthought.
Reduced Rework Risk
Our upfront DFM review is designed to proactively identify and resolve potential design flaws or manufacturability issues long before the first sheet of aluminum is cut. You get a fully manufacturable, spec-compliant part on the very first production run.
Scalable Volume
You can confidently initiate a project with a single prototype order, taking advantage of our no minimum order quantity (MOQ) policy. When your design is validated, you can scale directly into high-volume production batches without the friction of switching manufacturing suppliers or renegotiating your commercial terms.
Full Traceability
We understand that documented proof is non-negotiable for audits and regulated industries. Every order we ship includes Coordinate Measuring Machine (CMM) inspection reports alongside verifiable material certificates.
Every custom aluminum component we manufacture undergoes a rigorous, fully documented inspection protocol before it leaves our facility.
- ISO 9001 certified manufacturing: As an internationally recognized standard for quality management, our ISO 9001 certification dictates stringent process controls, proactive corrective actions, and rigorous supplier qualification procedures.
- Laser cutting tolerances to ±0.1 mm: We consistently hold cutting tolerances to ±0.1 mm on qualifying features. When your design requires extreme precision, we can achieve even tighter tolerances on specific dimensions through dedicated secondary machining operations.
- IATF 16949 compliance: We offer fully compliant manufacturing workflows. Upon request, this includes First Article Inspection (FAI) reports and CMM outputs fully annotated with Geometric Dimensioning and Tolerancing (GD&T) data.

China Aluminum Sheet Metal Fabrication FAQs
We work most frequently with 5052-H32 for enclosures and general sheet work, 6061-T6 for structural and aerospace applications, and 3003-H14 for ductile, low-cost applications.
We can form sheet thicknesses up to 12 mm, though the exact limit depends on your specific alloy grade and the required bend radius. To ensure angular accuracy and minimize springback, our engineering team uses offline bend sequence programming before any metal is formed.
Our fabrication team strictly follows AWS D1.2 structural welding standards for all aluminum weldments. This ensures high-quality structural aluminum assemblies and enclosures with complete process and material traceability.
No, you won’t. We operate with no minimum order quantity (MOQ), allowing you to validate a single prototype and scale into full production batches without changing suppliers, terms, or your primary point of contact.
Anodizing specifications are locked to your drawing before production begins. We coordinate with qualified anodizing partners to ensure the surface prep and alloy grade are compatible with the specified finish. Alloys like 6063 and 5052 anodize well; 6061 anodizes with slightly more variation in color consistency, which we flag during DFM review when relevant.
Because aluminum is a highly versatile material, we support a wide range of finishing applications. Our surface treatment options include Type II and Type III hard anodizing, chromate conversion (Alodine), powder coating, brushing, bead blasting, and standard deburring.
