Who invented metal casting?

Who invented metal casting?

The first castings can be dated back to ancient China in the 4th century B.C. Through the metalcasting process, molten metal is poured into a mold that matches the final dimensions of the finished product. While all metals can be cast, the most predominant are iron, aluminum, steel and copper-based alloys.

What materials are used for casting?

Metals and alloys such as bronze, brass, aluminum, silver, lead, and iron have been widely used for casting. Metal casts can be made directly from certain heat resistant silicone, metal, or sand molds.

What are metal molds made of?

Casting molds are usually formed from gray cast iron because it has about the best thermal fatigue resistance, but other materials include steel, bronze, and graphite. These metals are chosen because of their resistance to erosion and thermal fatigue.
