China Aerospace Sheet Metal Fabrication | Precision Parts
China aerospace sheet metal fabrication gives aerospace engineers and procurement teams access to tight-tolerance structural parts, enclosures, and brackets at competitive prices. Certified quality systems and full material traceability back this access.
At XTJ CNC, we’ve produced aerospace sheet metal fabrication components since 2005, serving OEM engineers and R&D teams across commercial aerospace, defense, UAV, and avionics applications. Whether you need a single prototype panel or a production batch of welded assemblies, we produce parts built to your exact drawings, tolerances, and documentation requirements.
Why Does Aerospace Sheet Metal Fabrication in China Matter?
Aerospace sheet metal fabrication isn’t general fabrication work. Parts used in aircraft structures, avionics housings, and UAV frames carry stricter tolerance, traceability, and material certification requirements compared to commercial or industrial applications. Getting it wrong means rework at best and a program delay or safety incident at worst.
China-based aerospace fabrication suppliers operate advanced fiber laser systems, CNC press brakes, and precision welding cells comparable to those found in Western aerospace supply chains. The question engineers should ask isn’t whether Chinese suppliers can hold aerospace tolerances; it’s whether a specific supplier has the certifications, documentation processes, and track record to prove it.
According to Grand View Research, demand for aerospace-grade sheet metal components is growing steadily as commercial aviation programs scale and the UAV sector expands. That growth makes qualified supplier selection more important than ever.
XTJ CNC holds ISO 9001 certification and supports AS9100-aligned documentation requirements on request. Our existing OEM client base includes Magna, Shimadzu Medical, BEKO, and Electrolux, demonstrating the level of supplier qualification we routinely pass.
What Makes Aerospace Sheet Metal Fabrication Different From General Fabrication?
Aerospace sheet metal work imposes requirements that standard commercial fabrication doesn't. Understanding where these requirements sit helps you qualify a supplier before you send your first drawing. Sheet metal fabrication across all industries involves cutting, bending, and joining flat metal stock, but aerospace applications add several layers of control.
Tighter dimensional tolerances: Aerospace structural brackets and panel skins routinely require profile tolerances of ±0.1 mm or better on laser-cut features. Bends must hold angle accuracy to ±0.5° to maintain assembly fit across multi-part structures.
Material traceability: Every piece of raw material used on an aerospace part must be traceable back to a certificate. This documentation includes the material grade, heat number, and chemical composition before cutting begins.
Certified material grades: Aerospace parts typically use alloy-specific grades such as aluminum 2024-T3, 7075-T6, or titanium Grade 5 rather than commercial-grade equivalents. Substituting a lower-specification material isn't acceptable, even if the geometry matches.
Surface treatment traceability: Finishing processes like anodizing, alodine (chromate conversion coating), and primer applications on aerospace parts must meet specific standards, such as AMS 2470 for hard anodize and AMS-C-5541 for chemical film. The process parameters and batch records are part of the documentation package.
First Article Inspection (FAI): Aerospace procurement teams require a full FAI report on new parts, documenting every dimension against the drawing with CMM-generated data.
What Aerospace Sheet Metal Fabrication Processes Do We Offer?
- Precision Laser Cutting: Our fiber laser systems cut aluminum, stainless steel, titanium, and steel sheet from 0.5 mm to 25 mm thick with positional tolerances to ±0.1 mm. Fiber lasers produce narrow kerfs and minimal heat-affected zones. These parameters are important when cutting aerospace alloys, where heat input can alter material properties near the cut edge.
- CNC Press Brake Bending: CNC press brakes hold bend angle accuracy to ±0.5° with offline programming that accounts for material spring-back. For aerospace brackets and skin panels where mating flanges must align across an assembly, consistent bend angles across a batch are non-negotiable.
- TIG Welding and Structural Assembly: We perform TIG welding on aluminum, stainless steel, and titanium weldments. Weld quality follows AWS D1.2 for aluminum and AWS D1.6 for stainless steel. Post-weld dimensional inspection with CMM equipment verifies that welded assemblies hold their geometric callouts.
- Aerospace Surface Finishing: We apply anodizing (Type II and Type III), chemical film (alodine/chromate conversion), powder coating, passivation, and bead blasting. Finishing specifications are locked to your drawing and process parameters are recorded. We don’t apply a default finish; every finish is specified and documented.
- Rapid Prototyping: Prototype aerospace sheet metal parts ship in three to five days. We support design iteration with fast-turnaround fabrication alongside our CNC machining services for parts that combine machined and formed features.
What Materials Do We Use for Aerospace Sheet Metal Fabrication?
Aerospace sheet metal fabrication demands specific alloy grades with known and certified mechanical properties. We work with the material grades specified on your drawing.
Aluminum 2024-T3 and 7075-T6: 2024-T3 offers high fatigue resistance and is the standard choice for wing skins, fuselage panels, and structural brackets in commercial aviation. 7075-T6 delivers higher tensile strength at the cost of lower corrosion resistance and is common in UAV frames and high-load structural fittings.
Aluminum 5052 and 6061: 5052 bends cleanly without cracking and suits ductwork, fairings, and enclosures where complex forming is required. 6061 balances strength and machinability for brackets and general structural sheet metal where 2024 or 7075 certification isn't required.
Stainless Steel 304 and 316L: Used for avionics enclosures, fluid system brackets, and structural parts in corrosive environments. Chloride exposure or sterilization cycles make 316L the preferred material.
Titanium Grade 5 (Ti-6Al-4V): High strength-to-weight ratio with excellent corrosion resistance. Standard for aerospace structural parts where weight reduction is critical and aluminum doesn't have the required strength. We cut and form titanium sheets up to six mm thick.
Inconel 625 and 718: Used in high-temperature aerospace applications such as exhaust systems, fire barriers, and nacelle components. These nickel superalloys retain strength at elevated temperatures where aluminum and steel would fail.
What Aerospace Sheet Metal Parts Does XTJ CNC Fabricate?
Aerospace sheet metal components span a wide range of structural, enclosure, and systems integration applications. Here are the part types our customers most frequently source from us.
Structural Brackets and Fittings
Sheet metal brackets and fittings connect structural members, mount system components, and transfer loads across airframe assemblies. These parts require tight hole-to-hole positional tolerances and precise bend angles to ensure assembly fit. We produce these from aluminum 2024, 7075, and 6061, with full dimensional reports on every order.
Enclosures and Avionics Housings
Avionics enclosures protect sensitive electronics from vibration, moisture, and electromagnetic interference. Sheet metal housings for line-replaceable units (LRUs) and rack-mount avionics require cosmetic surface finishes, tight seam tolerances, and in many cases, chemical film (alodine) treatment for electrical bonding. We fabricate and finish these in-house without outsourcing the finishing step.
Skin Panels and Fairings
Fuselage skins, wing fairings, and access panels are among the highest-precision sheet metal parts in an airframe. Contoured panels require accurate flat-pattern development before cutting to ensure that bends produce the correct final profile. We produce flat-profile and single-curvature panels from aluminum 2024 and 7075 sheet, with profile tolerances held to your drawing callout.
Ducting and Fluid System Brackets
Environmental control system (ECS) ducting, fuel system brackets, and hydraulic line supports operate in demanding thermal and vibration environments. Material selection for these parts balances weight, temperature resistance, and chemical compatibility with the fluid being carried. We fabricate ducting and fluid system hardware from aluminum, stainless steel, and titanium as specified.
UAV and Drone Structural Components
The UAV sector has driven significant demand for fast-turnaround aerospace sheet metal prototyping. Airframe ribs, motor mounts, payload bays, and landing gear brackets all require the same dimensional discipline as manned aircraft parts, but on shorter development cycles. Our three-to-five-day prototype lead time supports the rapid iteration pace of UAV programs. Learn more about our sheet metal fabrication capabilities for UAV and drone applications.
How Do We Ensure Quality in Our China Aerospace Sheet Metal Fabrication Services?
