A/356 Aluminum Sand Castings

Aluminum alloy A356.0 and 356.0 are a 7% Si, 0.3% Mg alloy with 0.2 Fe (max) and 0.10 Zn (max). The alloys have very good casting and machining characteristics. Typically they are used in the heat-treated condition of T5 and T6 hardness properties.

Corrosion resistance is excellent and it has very good weldability characteristics. Mechanical properties are rated excellent particularly if given a solution and aging treatment (T5, T6). The anodized appearance is gray in color. 

Typically this alloy is used in castings for aircraft parts, pump housings, impellers, high velocity blowers and structural castings where high strength is required. It can also be used as a substitute for aluminum alloy 6061.

The fact that 356.0 and A356.0 have good castability makes it a logical choice for intricate and complex castings where lightweight, pressure tightness and excellent mechanical properties are needed.

The A in front of an alloy designation denotes a higher purity version of the chemical composition.  The differences are in the impurity levels allowed for Fe, Cu, Mn, Cr, Zn, and Ti and are as follows (all maximums):
