Aluminum 2A12
Aluminum 2A12 is a highly machinable, high fatigue strength aluminum-copper-magnesium alloy that is heat treatable. Its poor corrosion resistance but can be enhanced with coatings or surface treatments. 🔧
Applications of Aluminum 2A12 include:
✈️ Aerospace Industry: Structural components such as wing ribs, spars, diaphragms, and part rivets for components below 150 degrees Celsius operational temperature.
🚗 Automotive & Transportation: Hubs for trucks, traffic vehicles, and compressors.
🏭 Industrial Use: Aircraft-grade polymer molds, screw-type rotary elements, and ultra-high-strength structural components.
Remember: Aluminum 2A12 performs satisfactorily with spot welding but may fail with other welding methods due to cracking.
