Description
Product description
Copper bar is a kind of non-ferrous metal processing bar, which has good processing performance and high electrical conductivity. It is mainly divided into brass rod (copper zinc alloy, cheaper) and red copper rod (higher copper content). It is mainly used for air conditioning pipes, refrigerator pipes, oil pipes, water supply pipes and various mechanical supporting materials, automobile synchronizer gear rings, marine pumps, valves, structural parts, friction accessories, etc.
Copper rod is a round long product made of copper with the same cross-section over its entire length. The copper round material can be soft, semi-hard or hard and is manufactured cold or hot-formed. The cold-rolled copper round bar has a diameter between 3 and 50 mm and a length of 1-5 m. The hot-rolled copper round bar has a diameter between 20 and 180 mm and a length of 1-5 m.
Copper is a relatively soft, easily malleable and tough heavy metal. It conducts heat and electricity excellently and is therefore used in various industrial areas. Cold forming increases the tensile strength of the metal, but at the same time lowers its elongation at break and conductivity. Copper can be forged very well at temperatures of 700 to 800 ° C.
The copper round rod with the material number 2.0090 (Cu-DHP) is available from us. This grade consists of a deoxidized copper (99.9%) with a limited residual content of phosphorus (0.015 – 0.04%). It is particularly well suited for use in areas with no high requirements in terms of electrical conductivity. The material is sensitive to solutions containing cyanide, halide and ammonia, oxidizing acids, hydrogen sulfide and sea water at high flow velocities. It is insensitive to drinking and industrial water, aqueous and alkaline solutions, pure water vapor, non-oxidizing acids and neutral salt solutions.
