What is the difference between cast aluminum and aluminum alloy?

- Sep 20, 2018-

Aluminum alloy is a large class, and the cast aluminum component is generally alloyed and is a kind of aluminum alloy.

Aluminum alloy can be divided into two major categories: deformed aluminum alloy and cast aluminum alloy according to the processing method:

The deformed aluminum alloy can withstand pressure processing and can be processed into various shapes and specifications of aluminum alloy materials. Mainly used in the manufacture of aviation equipment, construction doors and windows.

The deformed aluminum alloy is further divided into a non-heat treatable reinforced aluminum alloy and a heat treatable reinforced aluminum alloy. The non-heat-treatable reinforced type cannot be mechanically improved by heat treatment, and can only be strengthened by cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and rust-proof aluminum. The heat-treatable reinforced aluminum alloy can be improved in mechanical properties by heat treatment such as quenching and aging, and can be classified into hard aluminum, wrought aluminum, super-hard aluminum and special aluminum alloy.

Cast aluminum alloy can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum zinc alloy and aluminum rare earth alloy according to chemical composition, among which aluminum silicon alloy has hypereutectic silicon aluminum alloy and eutectic silicon aluminum alloy. Crystalline silicon aluminum alloy, cast aluminum alloy used in the as-cast state.
