5A05 aluminum Features and Applications

5A05 Al-Mg system for anti-rust aluminum alloy, non-heat strengthened. Good weld ability, corrosion resistance alloys can still apply to welding, atomic hydrogen welding, gas welding, welding. Its mach inability, the annealed state is poor, half-cold hardening state is still good.

 

5A05 alloy commonly used for manufacturing processes require high ductility, corrosion resistance, withstand moderate load of welded pipes, welded mailboxes and other liquid containers, as well as other parts; wire used for welding and rivets, rivet requires anodized. In other countries, the approximate alloys (such as 5456) for the production of armor plates, high-strength structural parts. Storage tanks, pressure vessels, and marine supplies, such as missing

Mechanical properties:

● Heat treatment:

 

1) Homogenization: Heat 460 ~ 475 ℃; holding 12 ~ 14h; air cooling.

2) Rapid thermal annealing: heating 310 ~ 350 ℃; holding time 30 ~ 120min; air or water.

3) High temperature annealing: heating 310 ~ 335 ℃; finished thickness ≥6mm or <6mm, the holding time of 30 ~ 180min or 30 ~ 120min; air cooling.

4) Low-temperature annealing: heating 250 ~ 300 ℃ or 150 ~ 180 ℃; holding time of 1 ~ 2h or air-cooled 2 ~ 3h Status: aluminum and aluminum alloy extruded seamless pipe (H112 condition)
