4032 (4032-T6, AlSi12.5MgCuNi) Aluminum

4032 aluminum is a 4000-series aluminum alloy. The main alloying addition is silicon. Cited properties are appropriate for the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. 4032 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-4032. Additionally, the EN chemical designation is AlSi12,5MgCuNi. The British Standard (BS) designation is DTD324B. The AFNOR (French) designation is A-S12UGN. And the UNS number is A94032.

It originally received its standard designation in 1954.

It has the highest tensile strength among the 4000-series alloys in the database.

The graph bars on the material properties cards below compare 4032 aluminum to: 4000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it’s 50% of the highest, and so on.

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.
