The difference between copper bar and brass bar

Brass bar and red copper bar, which is of great significance to the development of China's copper industry.Brass bar is an alloy of copper and zinc. If only composed of copper, zinc brass bar is called ordinary brass bar. Brass bar is often used in the manufacture of valves, water pipes, air conditioners, internal and external connecting pipes and radiators. Copper zinc binary alloy is called ordinary brass row or simple brass row. Three or more brass row is called special brass row or complex brass row.

Copper is copper elemental, because its color is purplish red named. See copper for various properties. Is industrial pure copper, its melting point is 1083℃, no isomerism transformation, the relative density of 8.9, five times that of magnesium. It's about 15% heavier than ordinary steel. Its rose red, the surface of the formation of oxide film is purple, so it is generally called red copper row. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper.

The main difference between brass row and red copper row is density and use:

Brass row density (8.93g/cm3) with mechanical bearing liner, wear resistance. Brass row castings are commonly used to make valves and pipe fittings. Ordinary brass row is very widely used, such as water tank belt, water supply and drainage pipe, medal, bellows, serpentine pipe, condensation pipe, shell case and a variety of complex shaped products, hardware, etc. With the increase of zinc content from H63 to H59, they can withstand hot processing very well, mostly used in various parts of machinery and electrical appliances, stamping parts and Musical Instruments.

Pure copper, also known as copper, density (7.83g/cm3}, melting point of 1083 degrees, no magnetic. Good electrical conductivity, thermal conductivity and corrosion resistance, toughness. Copper is ductile. Pure copper, the size of a drop of water, can be pulled into filaments up to two kilometers long, or rolled into almost transparent foil larger than a bed. The most valuable property of red copper is that it conducts electricity very well, second only to silver among all metals. But copper is so much cheaper than silver that it has become the hero of the electrical industry.

So brass row or luoyang copper row good answer is: brass row and copper row, is used in different fields, there is no pros and cons between them.
