Explanation

The ability of metal and alloy to make castings with correct size and shape and qualified internal quality by foundry method. It mainly includes the flow ability and filling capacity of liquid metal, the degree of gas absorption and oxidation when contacting with the medium, the range of crystallization temperature and crystallization characteristics during solidification, shrinkage and adaptability to molding materials. castability is a comprehensive index to measure metallic materials that can be produced by foundry method. In addition to being limited by the chemical composition of metal, it is also closely related to the selection of foundry process system.
