Mar 16, 2023

Material name: deformed aluminum and aluminum alloy, 2219 aluminum alloy surface anodized
It is an aluminum alloy with copper as the main alloying element

Grade: 2219
Characteristics and application of 2219 aluminum alloy surface anodized:
2219 aluminum alloy, American deformed aluminum and aluminum alloy. 2219 aluminum alloy has poor corrosion resistance and good machining performance; poor brazing properties, easy to arc welding and spot welding. Suitable for structural parts and high-strength welding parts that work at a high temperature of 315°C.
Standard comparison: American Aluminum Association (AA) 2219, UNS A92219, ISO R209 AlCu6Mn; China GB 2219 (LY19)
