Customized aerospace aluminum alloy die – castings
Processing materials: Aviation – grade aluminum alloys are used (such as A380, A356, ZL104, etc.).
Characteristics: High corrosion resistance, adaptable to complex aviation environments such as high humidity and salt spray.
Processes: High – pressure die – casting (with pressure up to over 1000 bar) or vacuum die – casting processes are adopted.
Accuracy: The tolerance grade can reach CT6 – CT8 (GB/T 6414), and the surface roughness is Ra≤3.2μm.
Customization: Full – process customization services from drawing design, mold development to mass production are supported.
Standards: Comply with AMS 2771 (heat treatment of aluminum alloys), ASTM B179 (die – casting standards) and AS9100 aviation quality management system.
