5383 H111 Aluminum
5383-H111 aluminum alloy is a type of aluminum alloy, which undergoes specific heat treatment and mechanical processing to be in the H111 condition. This alloy is widely used in environments that require good corrosion resistance and moderate strength.
H111 Condition 5383 Aluminum
In the alloy condition naming, the number and letter following the "H" represent the degree of heat treatment and strength of the metal during processing.
The H111 condition indicates that the metal has undergone strain hardening, but its strength is below the upper strength limit allowed by the H11 condition (1/8 hardness).
The H111 condition usually means that the aluminum alloy undergoes slight cold working (such as stretching or rolling) during processing, but has not been fully strengthened.
Aluminum alloys in this condition exhibit good machinability, but their strength and hardness are relatively low.
