What is A356-T6?

A356-T6 has two meanings:

1. The grade of cast aluminum alloy, namely cast aluminum alloy A356.

Cast aluminum alloy A356 is a typical aluminum-silicon alloy. It has good fluidity, airtightness, wear resistance, corrosion resistance, and no hot cracking tendency. Easy to weld and with highly high mechanical properties after heat treatment, it is one of the most common cast aluminum alloys.

2. Heat treatment state after casting, namely T6 state.

The casting aluminum alloy controls the heating speed to rise to a specific corresponding temperature, and then keeps it for a particular time, and cools at a certain speed to change the structure of the alloy, thereby improving the mechanical properties of the alloy, enhancing the corrosion resistance, improving the processing performance, and obtaining the size Stability; this process is called heat treatment, T6 is one of the heat treatment processes of aluminum alloy, namely quenching and complete aging. A356-T6 can only be produced by aluminum alloy gravity casting. A356 is not suitable for die-casting. Even the aluminum castings that are die-casted cannot be treated with T6.
