1, brass is composed of copper and zinc bai aluminum alloy, composed of copper, zinc brass du called zhi for general brass, if it is composed of more than two kinds of yuan dao elements of a variety of aluminum alloy is called unique brass. Brass has strong wear resistance, brass is often used to produce manufacturing gate valve, water pipe, central air conditioning inside and outside the machine connecting pipe and heat pipe radiator and so on.
2, purple copper alias red copper is copper hydroxide, because its color is dark purple and famous. Various characteristics see copper. Copper is the industrial production of pure copper, its melting point of 1083 ℃, no isotopic configuration changes, the density of 8.9, for the magnesium five times. The mass of the same volume is about 15% heavier than normal steel.
Purple copper because it has a rose-red color, the surface layer of air oxidation film produced after the blue-violet, so it is generally called purple copper. It is a copper with a certain amount of oxygen, so it is also known as oxygenated copper.
3, red copper that is pure copper, alias purple copper, is copper hydroxide, because of its color is dark purple and famous. Various properties see copper. Red copper is the industrial production of pure copper, its melting point of 1083 ℃, no isotopic configuration changes, the density of 8.9, for the magnesium five times.
The mass of the same volume is about 15% heavier than normal steel. Because it has a rose-red color, the surface layer produces air oxidation film is blue-violet, so it is generally called copper. It is copper with a certain amount of oxygen, so it is also known as oxygen-containing copper.
Red copper has very good electrical conductivity and heat transfer, ductility is very good, easy to press and cold working pressure production and processing, a lot of used in the production and manufacture of cable, cable wire, carbon brushes, spark discharge erosion of copper and other provisions of the conductivity of excellent goods.
