Aluminum Alloy 4032 is usually used as a material for making engine pistons, which has a composition of Aluminum (Al), 21%wt Silicon (Si), 0.82%wt Nickel (Ni) and 0.67%wt Copper (Cu).

4032 Aluminum Alloy has excellent machinability and drilling characteristics produced by a winning combination of controlled composition and cold finishing. Unique combination of in-service performance and manufacturing productivity that ensure superior wear resistance, tighter tolerances, exemplary surface finish and consistency. 4032 Aluminum eliminates the need for hard coat anodizing used in high temperature forging applications. 4032 is suggested for applications requiring wear and abrasion resistance.

Aluminum 4032 alloys are typically used for parts of equipment or automobiles that require a high wear resistance, low coefficient of thermal expansion, have good weldability, good corrosion resistance and has the ability to replace 12L14 steel based on wear resistance. This can reduce product flow time (elimination of anodizing) as well as eliminate the environmental issues associated with anodizing. 4032 is often used in the auto industry for master brake cylinders, transmission valves, forged pistons, bushings for rack and pinion steering systems as well as other applications such as copier parts, sound recording devices, bearings and hydraulic applications.

Benefits of using this 4032 aluminium alloy include:

STRONGEST 4000 SERIES ALUMINIUM

FAIR TO GOOD MACHINABILITY

CAN BE WELDED

CAN BE USED IN LOW AND HIGH-TEMPERATURE APPLICATIONS

MORE DURABLE AND LIGHTER THAN 2618A

4032 aluminium alloy is extensively used in the production of racing pistons, engine components and chassis components.
