Cast alloys

Comparing with wrought alloys, casting alloys consists of larger amounts of alloy components like silicon and copper which results in a heterogeneous structure. Thus it contains phase impurities. This may lead to notches and cracks. To block this metallurgical and foundry environment should keep in optimum condition. In fatigue, the elongation, strength, brittleness, ductility etc. of most cast products is relatively poor in comparison with their wrought counterparts. The strongest of the common casting alloys is heat treated 201.0/AlCu4Ti.
