Copper and Copper Alloys Casting Problems

These alloys are poured into many types of castings such as sand, shell, investment, permanent mold, chemical sand, centrifugal, and die casting. The copperbase casting alloy family can be subdivided into three groups according to solidifiion (freezing range). Unlike pure metals, alloys solidify over a range of temperatures.
