Brief introduction of deformed Aluminum alloy

1.1 Classification of deformed aluminum alloy

Aluminum alloy root its chemical composition of the production process characteristics of different, can be divided into casting aluminum alloy and deformation aluminum alloy.  
Deformed aluminum alloy has high strength and good plasticity, can be molded by pressure processing, manufacturing of various materials and semi-finished products.  

Classification of deformed aluminum alloy,  

According to the characteristics of heat treatment, the alloy can be divided into heat treatment can be strengthened alloy and heat treatment can not be strengthened alloy.  

Heat treatment non-strengthening alloys - alloys that cannot be strengthened by heat treatment.  

Alloys that can be strengthened by heat treatment - alloys whose mechanical strength can be improved by heat treatment (quenching, aging).  

According to the chemical composition of the alloy, the deformed aluminum alloy can be divided into different alloy systems  

1.2 State and code of deformed aluminum alloy

Base status code and name

Subdivision status code

1.2.1 subdivision state of H

The first number after H indicates the basic handler to obtain the state.  
H1一一一Pure work hardening

H2一一Work hardening and incomplete annealing state

H3一一Work hardening and stabilization treatment

H4一一一Work hardening and paint treatment status

The second number after H indicates the degree of work hardening of the product.

1.2.2 subdivision state of T

T is followed by the first digit of 0-10, which represents the basic processing process of the product. Such as,  

T4一一一After solution treatment, natural aging reaches basically stable state.  Suitable for solution treatment, no longer cold processing (can be straightened, levelled, but does not affect the limit of mechanical properties) of the product.  

T5一一It is cooled by a high temperature molding process and then subjected to artificial aging.  It is suitable for artificial aging products after cooling by high temperature molding process without cold processing (can be straightened, levelled, but does not affect mechanical properties limit).  

T6一一The condition of artificial aging after solution treatment.  Suitable for solution treatment, no longer cold processing   (can be straightened, levelled, but does not affect mechanical properties limit).
