Multipurpose Aluminum (Alloy 6061)A
combination of good strength, corrosion resistance, and machinability
makes this the most widely used aluminum.
It has less strength than
Alloys 2024 and 7075, but better corrosion resistance and weldability.
It's heat treatable and
resists cracking due to stress. Commonly used
for vehicle parts and pipe fittings. Nonmagnetic. Temperature range is
-320° to +300° F.
Hardness: 60-95 Brinell
Yield Strength: 35,000 psi
Meets ASTM B 209
