We all know that 2A12 aluminum alloy material is needed through heat treatment, so today 2A12 aluminum tube manufacturers will give you an introduction, 2A12 aluminum tube heat treatment basic principle.

1. Solidification process of binary alloy

The solidification of binary alloys with the primary composition of alloy and crystal is often different, different parts of the ingredients, castings of 2 a12 aluminium tube liquid copper 33%, when the temperature is lower 33% of the copper alloy, with eutectic phase separation, if less than 5.7% copper content for solid solution segregation of the relationship, the final solidification can be for copper, 33% of the eutectic phase had adverse effect on the eutectic relative mechanical properties, and heat treatment is to solve the problem.

2. Types of heat treatment

The elements commonly added in 2A12 aluminum tube are zinc, magnesium, copper, manganese, etc. 2A12 aluminum tube is heat-treatable material.Basic quenching solid solution heat treatment steps at high temperature, and then precipitation hardening treatment, can be alloy dissolved alkali in uniform segregation casting, and then quickly cooled to room temperature, to produce susaturated state, when precipitation hardening, susaturated solute, and then evenly deposited to achieve the hardening effect.

The above is the introduction of the basic principle of 2A12 aluminum tube heat treatment. If you need 2A12 aluminum tube, please contact us.
