An explanation of the characteristics of aluminum alloys in precision casting

The characteristics of aluminum alloys in precision casting are:

1. Aluminum alloy has a lower melting point than ordinary metals, but it can meet the requirements of most situations.

2. Aluminum alloy has good thermal conductivity, the heat of molten aluminum can be quickly transferred to the casting mold, and the casting cycle is short.

3. Hydrogen and other harmful gases in the aluminum alloy melt can be effectively controlled through treatment.

4. When aluminum alloy is cast, there is no tendency for hot brittle cracking and tearing.

5. Aluminum alloy has good chemical stability and strong corrosion resistance.

6. Aluminum alloy is not prone to surface defects, the surface of the casting has good surface finish and gloss, and it is easy to surface treatment.

7. Aluminum alloy has good fluidity when casting.
