Plastic behavior and use of brass wires

The friend that is engaged in metal industry knows, brass wire is a kind of copper wire that contains other alloy composition, the price is relative to red copper wire, it wants more cheaper, its conductivity and plasticity are less than red copper, but its strength and hardness want a few higher. Brass is copper and zinc alloy material, the simplest brass is copper, zinc binary alloy, called simple brass, or ordinary brass, change the content of zinc in brass, you can get different mechanical properties of brass.

The higher the zinc content of brass wire, the higher its strength, slightly less plasticity. The zinc content of brass used in industry is not more than 45%, and the higher zinc content will produce brittleness, so that the alloy performance deteriorates. Adding 1% tin to brass can significantly improve the ability of brass to resist sea water and Marine atmospheric corrosion, so called "navy brass", tin can improve the cutting performance of brass.

Lead brass wire is usually said to be easy to cut gb copper, the main purpose of adding lead is to improve the machinability and wear resistance, lead has little effect on the strength of brass. Carved copper is also a kind of lead brass, most brass has good color, processing, ductility, easy to electroplate or coating.

Of course, in industry and civil, according to the use of different characteristics to choose different materials, do not do wire, more soft, copper wire is better, if it is to do the connection, where the screws choose brass wire.
