What is brass, red copper and red copper, and what is the difference

Brass, red copper, red copper: ductility, conductivity, plasticity are different, the difference is as follows:

1. There is a certain amount of natural copper in nature. Natural copper without artificial doping of other substances, namely pure copper, also known as red copper, it has a certain metallic luster and ductility, it is easy to be valued and used.

Pure copper is purplish red metal, commonly known as "red copper", "red copper" or "red copper". Pure copper is malleable. Pure copper, as big as a drop of water, can be stretched to two kilometers of filaments, or rolled into an almost transparent foil larger than a bed.

The most valuable property of pure copper is that it conducts electricity very well, second only to silver among all metals. But copper was so much cheaper than silver that it became the star of the electrical industry. Pure copper is much more widely used than pure iron. Every year, 50% of copper is purified into pure copper by electrolysis and used in the electrical industry.

2, brass is copper and zinc alloy, high hardness. The simplest brass is a copper-zinc binary alloy called simple brass or plain brass.

Brass is a kind of copper containing other alloy components, less expensive than copper, less conductive and plastic than copper. But I'm a little harder for strength. In industry and civil, according to the use of different characteristics to choose different materials, can not be generalized which one is good. Such as wire, the requirements are softer, copper is better. If the joint is seated, brass is used in the place of screws.

3, copper, also known as red copper, that is, pure copper.

Copper is a relatively pure pain, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is poor.
