One category : copper tube copper plate copper rod copper row copper belt copper wire copper wire (TP2 T2 TU1);
Category II: brass brass brass brass brass brass brass (H62 H63 H65 H68 H70).
Copper: The copper content is more than 99.90%. It has the good characteristics of copper metal, a good basic metal, and it is widely used in various fields of industry and civil use, and plays an important role.
TP2 is phosphorus-deoxidized copper and contains 0.015-0.04% of phosphorus. It shows good welding performance and cold bending performance. It is widely used in the manufacturing fields of air conditioning and refrigeration connection pipes, cooker gas connection pipes, water channel pipes, and electric heat pipes. .
T2 is pure copper with copper content higher than 99.90%. T2 copper tubing will be the first choice when users have high conductivity requirements for materials. TU1 is an oxygen-free copper with a copper content of 99.97%, extremely low oxygen and impurity content, high purity, excellent electrical conductivity, excellent thermal conductivity, good ductility, good processability, welding, corrosion resistance, and cold resistance.
Due to the high demands and high costs of its production, the price of its products is much higher than that of other types of copper pipes. Brass: Copper-zinc alloy tubes. The number following the H-letter in grades often represents the middle value of the copper content. The zinc content is the remaining amount.
Brass tubes of different grades, with higher and higher copper content, exhibit better quality and elongation performance and possess higher strength than copper tubes. Because of its better economy, it has become a substitute material for copper pipes and is widely used.
