2219 aluminium blocks is American deformed aluminum and aluminum alloy. 2219 aluminium blocks has poor corrosion resistance, but good mechanical processing performance; poor brazing performance, 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.
The chemical composition of 2219 aluminium blocks:
Si: 0.20
Fe: 0.30
Cu: 5.8~6.9
Mn: 0.20~0.40
Mg: 0.02
Zn: 0.10
Ti: 0.29~0.10
Zr: 0.10~0.25
V: 0.05~0.25
Other single: 0.05, 0.15 margin
Application of 2219 aluminium blocks
2219 aluminium blocks is suitable for the production of structural parts and high-strength welded parts that work at a high temperature of 315°C, and is widely used in the aerospace and aviation industries.
