EN AW-4032
EN AW-4032 – WEAR-RESISTANT
EN AW-4032 belongs to the group of heat-treatable alloys. Therefore, it is necessary to carry out a heat treatment such as solution annealing followed by artificial aging. Only then can the alloy develop its full potential. 4032 is the alloy with the highest achievable strength of the 4000 group and is often used as a piston alloy. Due to the very low ductility caused by its high silicon content, this alloy is difficult to press. LEICHTMETALL is also able to cast special non-standard variants of this alloy with over 20% silicon. Get in touch with us today.
EN AW-4032 applications
EN AW-4032 is often used as a piston, bearing or bushing alloy. Everywhere where high wear resistance combined with low weight is required.

Mechanical properties
There is no standard for cast round rods (cast billets / bolts) that defines mechanical properties. A Brinell hardness in the homogenised state of approx. The homogenized state (=”O3“ according to EN515) is comparable in strength with the annealed state (=”O“) for extruded products. The final strength is essentially adjusted by the reshaping process and/or the heat treatments
