Brass Bar
Brass rod is the most widely used and cheapest copper-based alloy. They have relatively good corrosion resistance, moderately high strength, and in some compositions are particularly ductile, and have excellent forming characteristics when shaped by pressing, deep drawing, rolling, and machining. The improvement in tensile properties is a result of cold working. After cold working, it can be softened and recrystallized by proper annealing. The addition of lead to brass enables free cutting of free-cutting alloys in which the elemental lead is present in the form of uniformly dispersed particles. High lead content results in relatively low ductility and plasticity.
