Bronze: Bronze is a metal smelting and casting history of early alloys, in the pure copper (bronze) in the addition of tin, lead alloy, has a special importance and historical significance
Chromium copper: chromium copper at room temperature and higher temperatures (400 ℃) with high strength and hardness, electrical and thermal conductivity of a good material.
White Copper: White Copper is a copper-based alloy with nickel as the main added element, which is silver-white in color and has a metallic luster, hence the name White Copper.
Silver copper: Silver copper alloy is a silver alloy with copper as the main alloying element. In order to improve performance, often also add nickel, beryllium, lithium, vanadium and other elements. Mainly used as electrical contact material and brazing material.
(Purple copper: the melting point of purple copper is 1083 ℃) purple copper, is industrial pure copper. Because it has a rose-red color, the surface of the formation of oxide film is purple, it is generally known as purple copper, also known as red copper. It is copper containing a certain amount of oxygen, and thus also known as oxygenated copper, and can sometimes be regarded as a copper alloy.
Red copper: red copper generally refers to purple copper. Violet copper, is industrially pure copper. Because of its rose-red color, the surface of the formation of oxide film is purple, so generally known as purple copper, also known as red copper. It is copper containing a certain amount of oxygen, and thus also known as oxygenated copper, and can sometimes be regarded as a copper alloy.
Pure copper: pure copper is a soft metal, pure copper melting point of 1083 ℃) surface just cut for the reddish-orange color with metallic luster, the monomers are purple-red. Good ductility, thermal conductivity and high electrical conductivity, so in the cable and electrical and electronic components is the most commonly used materials, can also be used as building materials, can be composed of many kinds of alloys.
Oxygen-free copper: Pure copper that does not contain oxygen or any deoxidizer residue. However, it still contains very small amounts of oxygen and some impurities.
Copper cathode: It is a non-ferrous metal that has a very close relationship with human beings, and is widely used in the fields of electrical, light industry, machinery manufacturing, construction industry, defense industry, etc. It is second only to aluminum in the consumption of non-ferrous metal materials in China.
In the manufacture of machinery and transport vehicles, it is used in the manufacture of industrial valves and fittings, instruments, slide bearings, molds, heat exchangers and pumps.
Phosphorus deoxidized copper: Phosphorus deoxidized copper requires copper content of not less than 99.5% (mass fraction), residual phosphorus content of not more than 0.04% (mass fraction).
