Aluminum gravity casting & sand casting

Place of Origin:	Zhejiang

Aluminum gravity casting and sand casting process is always used for heavy part with big wall thickness and very strong mechanical property after T6 heat treatment. Its also better to avoid porosity inside casting after secondary machining. Gravity casting part is nice looking with better surface than sand casting, but sand casting is more flexibility even it is very complicated shape. 356 T6 is the most common raw material.
