B2B Sourcing Guide on the Metallurgy, Anodizing Chemistry, and Surface Preservation of Aircraft-Grade Aluminum.
7075 aluminum alloy is heavily alloyed with zinc (5.6% - 6.1%), magnesium, and copper. While this chemical composition produces mechanical strengths comparable to some steels (tensile strength up to 572 MPa in T6 temper), it presents major challenges during chemical surface treatments. The high zinc and copper contents increase susceptibility to galvanic cell formation in the acid electrolyte, resulting in localized dissolution, burning, or high coating porosity if parameters are poorly managed.
At Ningbo Jiangbei XinYe Metal Works, we resolve these challenges using optimized Type II (Sulfuric) and Type III (Hardcoat) anodizing protocols. We continuously monitor and adjust bath temperatures, acid concentrations, and voltage ramp-up rates. This prevents micro-cracking and guarantees structural integrity for defense and aerospace components.
For industrial applications, choosing the right anodizing type determines component longevity:
| Property / Parameter | Standard Anodizing (Type II) | Hardcoat Anodizing (Type III) | Xinye Custom Solution for 7075-T6 |
|---|---|---|---|
| Coating Thickness | 5 - 25 microns (µm) | 50 - 100 microns (µm) | Pulsed current control to prevent burning |
| Micro-Hardness | 200 - 300 HV | 400 - 500+ HV | Optimized low-temperature electrolyte baths |
| Corrosion Resistance | 96 hours ASTM B117 salt spray | 240+ hours ASTM B117 salt spray | PTFE / Nickel Acetate Hot Seal options |
| Primary Application | Decorative & light automotive parts | Aerospace components, gears, sliding surfaces | Military and aerospace wear assemblies |
Founded in 1996 as a family business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has grown into a highly reliable, owner-managed B2B manufacturing corporation. We operate from the Ningbo Jiangbei Industrial Zone, within a 3-hour high-speed train connection from Shanghai International Airport.
Over the past 28 years, we have built a comprehensive production ecosystem. Our facilities cover 16,000 square meters of production space, with another 11,000 square meters planned for future construction. We employ 130 staff, including 80 production specialists and 50 experts in R&D, engineering, and quality control.
We provide fully integrated manufacturing services: custom CNC machining, aluminum alloy hot forging, wax die stainless casting, stamping, deep drawing, and advanced surface treatments, including anodizing and electropolishing.
Combining industrial cluster efficiencies, logistics advantages, and high-precision quality control.
Our location in Ningbo provides direct access to high-quality raw materials, specialized heat treatment providers, and modern tooling workshops. This allows us to offer shorter lead times and highly competitive pricing for custom B2B orders.
Located near Ningbo Port—one of the busiest shipping hubs globally—we provide direct sea transport connections. This ensures fast, reliable, and cost-effective distribution of your custom metal components worldwide.
To deliver consistent quality on demanding geometries, we utilize high-precision CNC machining centers and advanced hot forging presses imported directly from Japan. This equipment supports highly repeatable, tight-tolerance manufacturing.

Our standard manufacturing shifts run 16 hours per day, 6 days a week. To support urgent projects, we can transition to a 24/7 continuous operation schedule within 30 days.
We actively invest in expanding our capacity. Our available facility land supports rapid scaling, allowing us to install customer-specific manufacturing cells or scale overall production volume as needed.
Operating under ISO 9001-2015 and SA8000 certifications to ensure complete batch traceability and dimensional compliance.
For high-strength anodized components, quality control begins with raw material verification. We analyze every incoming billet using our GNR Spectrum Analyzer to verify composition (specifically copper, zinc, and magnesium percentages) before forging or machining.
Our quality control program applies across all manufacturing stages:
We provide full documentation, including Certificates of Analysis (CoA), material conformance reports, and dimensional checklists, ensuring compliance with REACH and RoHS standards.
Sourcing strategies for global buyers matching regulatory updates, sustainability, and technological shifts.
Environmental standards restrict wastewater and the use of heavy metals. We focus on zero-discharge filtration loops and acid recovery systems. Our anodizing lines utilize eco-friendly sealing processes that comply with REACH and RoHS standards.
Replacing steel with lightweight 7075-T6 aluminum alloys continues to grow in automotive design. High-precision hard anodizing provides the necessary wear resistance, allowing these components to perform reliably under high-stress conditions.
Using 4-axis and 5-axis CNC machines reduces human error and shortens cycle times. We continually upgrade our machining centers to support complex custom geometries with high dimensional accuracy.
From the initial engineering review to mass production and logistics, we ensure quality at every stage.
Initial design and specification review, covering custom tooling requirements, material selection, target lead times, and technical tolerances.
