Products Description

Copper screws are screws made of copper as raw material. Copper has good electrical conductivity, thermal conductivity, ductility and corrosion resistance.Common copper screw materials include brass, bronze and so on.

Some of the copper screws are characterized as follows:
1. Brass: is an alloy of copper and zinc, in addition to better electrical and thermal conductivity, but also has a bright color, superior gloss performance, non-magnetic, easy to weld and so on. Brass can be divided into different types, such as 59 copper, 65 copper, 68 copper, 70 copper, etc., of which 59 copper is more widely used, while the color of 65 copper screws is the closest to gold, with the increase of zinc in the copper screws, the color will gradually become lighter and reddish. With the increase of zinc in the copper screws, the color will gradually become lighter and reddish. Some high-grade gold products will use 65 copper screws more.
2. Bronze: is an alloy of copper and tin, may also contain zinc, nickel, phosphorus and other alloying elements. Bronze screws have high strength and corrosion resistance.
3. Oxygen-free copper: a high-purity copper with a purity of up to 99.99%, also known as red copper (C1020). Screws made from this copper alloy are mainly used in high-end homes and high-grade gold-colored products.
