In August,we made a batch ZL104 Aluminum Sand Castings for Compressor Casing which we adopt sand casting process.

Scope of application of ZL104 Aluminum Sand Castings is as below:

Heat treatment can be strengthened. Its strength is higher than ZL101，ZL102 and other Al alloys. This Al alloy has good casting performance, no tendency of thermal cracking, high air tightness, and line shrinkage. But the tendency of forming pinhole is more complicated. It has good corrosion resistance, general machinability and weldability.

Mechanical properties of ZL104 Aluminum Sand Castings is as below:

1. Deformation b (MPa) of tensile strength is greater than or equal to 195.
2. Elongation δ5 (%) is greater than or equal to 1.5.
3. The Hardness is HB65 -250.
4. Heat treatment specification can be treated to annealing, aging or tempering: 175 + 5 ℃, 10 ~ 15 hours air cooling.
5. Casting method is metal mold casting and sand casting.
