Brass is better or copper is better

Copper, copper is a relatively pure kind of copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength and hardness are poor, brass is a kind of copper containing other alloy components, the price is cheaper than copper, electrical conductivity and plasticity is less than copper, but the strength and hardness are higher.

Brass is an alloy of copper and zinc. The simplest brasses are copper-zinc binary alloys called simple brass or plain brass, and varying the amount of zinc in the brass can result in brasses with different mechanical properties. The higher the zinc content in brass, the higher the strength and the lower the plasticity.

The use of red copper

More than 50% of the copper per year is purified by electrolysis into pure copper for use in the electrical industry. The copper here is indeed very pure, containing more than 99.95% copper. A very small amount of impurities, especially phosphorus, arsenic, aluminum and so on, will greatly reduce the conductivity of copper.

It is mainly used for making electrical equipment such as generator, bus, cable, switching device, transformer and heat exchanger, pipeline, solar heating device, plate collector and other thermal conductivity equipment. The oxygen content of copper (copper smelting is easy to mix a small amount of oxygen) has a great impact on the conductivity, and the copper used in the electrical industry must generally be oxygen-free copper.
