Yield strengths vary from 35 MPa for a low-strength aluminum to greater than 1400 MPa for very high-strength steels. Several features of the solute and solvent atoms determine the degree to which the former dissolves in the latter. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Melting point of tin bronze UNS C90500 gun metal is around 1000C. Copper is used mostly as a pure metal, but when greater hardness is required, it is put into such alloys as brass and bronze (5% of total use). Copper is a soft, tough, ductile and malleable material. Mechanical Properties of Copper and Copper Alloys at Low Temperatures Publist#: 144/8 Copper alloys become stronger and more ductile as temperature goes down. In general,meltingis aphase changeof a substance from the solid to the liquid phase. In Table 2 the average data for each alloy are tabulated for all tests and temperatures.
