What is the national standard for hardness of 2024 aluminium alloy?

The national standard for 2024 aluminium alloy is GB/T 3191-1998, formerly known as LD10, standard GB/T 3191-1998. 2024 aluminium alloy is a material belonging to hard aluminium alloy, with the main chemical composition of zinc, iron, magnesium and aluminium, etc. It has good machinability, good electrical resistance, spot welding and seam welding performance.

Yield strength of aluminium alloys and steel?

The tensile strength of industrial pure aluminium alloy:80~100MPa, the tensile strength of common aluminium alloy 5 series antirust aluminium alloy:265M, the tensile strength of 3A21:<167MPa. the tensile strength of hard aluminium 2024 aluminium alloy is relatively high, greater than 300MPa, the tensile strength of 2A12:390~420MPa. the tensile strength of other 2 series aluminium alloy:315~345MPa The tensile strength of other 2 series aluminium alloys is 315~345MPa.

2024 aluminium alloy heat treatment hardness

2A12 is equivalent to the American standard 2024, generally according to GB/T228 standard specimen processing after tensile test, to get the tensile strength, without hardness to express, GB/T 3880.2 provides the mechanical properties of the plate. GB/T 3191-2010 aluminum and aluminum alloy extrusion bar, > φ22 ~ 150mm tensile strength of not less than 420MPa.

What is the yield strength of aluminium alloys?

The tensile strength of rust-proof aluminium 5A50:265MPa, the tensile strength of 2024 aluminium alloy:315~345MPa, the tensile strength of industrial pure aluminium:80~100MPa.
