What Is A356 Aluminum Casting Alloy?
A356 aluminum casting alloy is a 7% Si, 0.3% Mg alloy with 0.2 Fe (max) and 0.10 Zn (max). A356 aluminum casting alloy has very good casting and machining characteristics. A356 aluminum casting alloy is used for aircraft parts, pump housings, impellers, high velocity blowers and structural castings where high strength is required. A356 aluminum casting alloy can also be used as a substitute for aluminum alloy 6061. It is typically used in the heat-treated condition of T5 and T6 hardness properties.
A356 aluminum casting alloy has good castability, this makes it a logical choice for intricate and complex castings where lightweight, pressure tightness and excellent mechanical properties are needed.
A356 Aluminum Casting T6 Heat Treatment Process
T6 heat treatment process is a 2 step process. The A356 aluminum castings are first allowed to cool naturally and are then heated at an elevated temperature in high temperature ovens. After a set period of time the A356 aluminum castings are quickly quenched and then are moved to low temperature ovens for the second step of the process.
T6 heat treatment of A356 aluminum castings offers increase in hardness and other mechanical properties, which is often required for many applications.
Advantages of A356 Aluminum Casting
- Excellent in corrosion resistance
- Very good weldability characteristics
- Mechanical properties are rated excellent particularly if given a solution and aging treatment (T5, T6)
