The difference between the copper brass, tin bronze

Copper rose red metal, copper oxide film formed on the surface after the purple copper copper or copper is often called. The density is 8-9g/cm3 and the melting point is 1083 degrees C. Pure copper is very good, a lot of used in the manufacture of wire and cable, brush; thermal conductivity, magnetic instrument used to manufacture beware of magnetic interference, such as compass, aviation instrumentation; good plasticity, easy to hot and cold pressure processing, can be made into tubes, rods, wire, strip, plate, copper foil. 
brass is an alloy of copper and zinc. The simplest brass is a copper zinc alloy two, known as a simple brass or brass. Changing the content of zinc in brass can be obtained with different mechanical properties of brass. The higher the content of zinc in brass, the strength is higher, the plastic is slightly lower. The amount of brass used in the industry is not more than 45%, and the content of zinc will be brittle. 
an alloy history the earliest application is refers to the original tin bronze, copper tin alloy, because the color is gray green, so called bronze. Tin bronze has high mechanical properties, good corrosion resistance, good corrosion resistance and casting performance; the heat and gas sensitivity is small, good welding performance, no ferromagnetic, small shrinkage coefficient. The corrosion resistance of tin bronze in atmosphere, sea water, fresh water and steam is higher than that of brass.
