Which casting is suitable for gravity casting of aluminum alloy?

Because of its unique process characteristics and advantages, gravity casting of aluminum alloy is suitable for the production of a variety of castings. The following are some types of castings suitable for gravity casting of aluminum alloy:

1. Large and complex structural castings
Advantages: Aluminum alloy gravity casting can effectively fill molds with large and complex structures to ensure the integrity and integrity of the casting.

Application examples: automobile engine cylinder block, gearbox housing, etc., these castings usually have a large volume and complex internal structure, and need a good casting process to ensure its quality.

2. High precision castings
Features: Aluminum alloy gravity casting can obtain higher dimensional accuracy and lower surface roughness, which meets the application scenarios requiring higher casting accuracy.

Application examples: precision mechanical parts, electronic communication equipment housings, etc., these castings require precise dimensions and smooth surface quality to ensure their stability and reliability during use.

3. Castings with large wall thickness
Advantages: Aluminum alloy gravity casting can better deal with castings with large wall thickness, to avoid cracks, shrinkage holes and other defects in the casting process.

Application examples: heavy machinery parts, aluminum alloy components for construction, etc., these castings need to withstand large loads and stresses, so there are high requirements for their wall thickness and internal quality.
