4032 Aluminum Alloy Bar

4032 aluminum alloy refers to American wrought aluminum and aluminum alloy. 4032 aluminum alloy has a large thermal expansion coefficient, high high temperature strength, and good high temperature corrosion resistance. It is used for processing forged pistons.

4032 aluminum alloys are known for strong corrosion resistance. 4032 aluminum alloys are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F), and tend to lose some of its strength. However, the strength of Aluminium/Aluminum alloys can be enhanced at subzero temperatures, making them ideal low-temperature alloys.
