2618A Aluminium

2618A is used in racing engine piston production and offers unique performance characteristics, which make it an ideal choice.

2618A Aluminium (DTD 5014A) was one of the first aluminium alloy products sold by Smiths High Performance. Although initially developed for aerospace applications, the product has become a popular engineering material in the motorsport sector due to the alloy's high strength. Grade 2618A contains copper and aluminium, offering good machinability and fair corrosion resistance in atmospheric conditions.

High Temperature Performance:

Components subjected to high operating temperatures benefit from 2618A's performance characteristics.

Supply Options:

The product is available in forgings, plates, bars and tubes. 2618A aluminium is popular in applications including racing engine components, pistons, chassis components and applications requiring better performance at higher temperatures. The alloy retains its mechanical strength up to 200°C and deployment up to a maximum temperature of 300°C.

Comparisons with 4032:

2618A aluminium offers improved strength and ductility compared to 4032 aluminium. However, 4032 is stiffer with a better wear rate. Both these alloys continue to be a leading engineering material for piston manufacture.
