Question: What are the compositions of brass, how can this metal be heat-treated, what is the melting point of this metal?

Answer: Brass is an alloy of copper and zinc, with varying degrees of mixing. It is a substitution alloy, which means the copper and zinc elements substitute each other in microstructure matrix positions. This behavior translates into a metal which has a lower melting point in between that of its elements (Cu=1084, 83ºC, Zn=419, 58ºC) in pure state. Usually, the possibility of heat treatment will depend on what are you trying to achieve. For the substitution range of compositions, for example, you cannot obtain hardening from heat-treating.
