In nature, brass and copper, respectively in a different form, but because of a lot of people don't really know to its, so often there will be such a problem, such as "good good brass or copper, small make up trying to tell you, actually in different areas, brass and copper, and no relative said.

 

Brass is an alloy of copper and zinc. If it's just copper and zinc, it's called ordinary brass. Brass is often used to make valves, water pipes, air conditioners and other connecting pipes and radiators. Brass with zinc as the main addition of copper alloy, with beautiful yellow, collectively known as brass. Copper zinc alloy is called ordinary brass or simple brass. Brass of more than three yuan is called special brass or complex brass.

 

Copper is the single substance of copper, which is named for its purple color. Copper is found in all sorts of properties. Copper is the industry of pure copper, its melting point is 1083 ℃, no with heterogeneous change, relative density 8.9, magnesium for five times. It's about 15% heavier than normal steel. It has rose-red, the surface of the oxide film is purple, so it is commonly known as copper. It is copper containing certain oxygen, so it is called oxygen-containing copper.

 

The main difference between brass and copper is the difference between density and purpose:

 

The density of brass is 8.93g/cm3 multi-purpose and mechanical bearing liner, wear-resisting. Brass castings are commonly used to make valves and pipe fittings. The use of common brass is very wide, such as water tank, water supply and drainage tube, medal, bellows, serpentine tube, condensing tube, shell and various kinds of complicated products, small hardware etc. With the increase of zinc content from H63 to H59, they are able to handle hot processing well, and are used in various parts, stamping parts and instruments of machinery and electric appliances.

 

Pure copper, also known as copper, has a density of 7.83 g/cm3, with a melting point of 1083 degrees and no magnetism. Good conduction, thermal conductivity and corrosion resistance, toughness. Copper is malleable. Pure copper, as small as a drop of water, can grow up to two kilometers of filaments, or be rolled over into almost transparent foil that is larger than a bed. The most valuable property of copper is that it conducts electricity very well, second only to silver in all metals. But copper is much cheaper than silver, making it the "main character" of the electrical industry.

 

So brass is good, but the answer is that brass and copper are used in different fields, and there is no better one between them.
