>>Material Characteristics:
1. With good fluidity, no hot cracking tendency, line shrinkage, good air tightness and other good casting performance.
2. Small specific gravity, good corrosion resistance, easy gas welding, with the increase of casting wall thickness, the degree of strength reduction is small, the use of the cast state, after deterioration of mechanical properties.
3. The ingot fracture is dense, without slag and non-metallic inclusions.
>>Application:
Typically this alloy is used in castings for aircraft parts, pump housings, impellers, high velocity blowers and structural castings where high strength is required. Consequence of exceeding impurity limits.
