Material Name: T2 Copper Tube


Brass tubes, also known as copper tubes, are a type of non-ferrous metal tube, which are cold-rolled and drawn seamless tubes. Trace impurities in brass significantly affect its electrical and thermal conductivity. Titanium, phosphorus, iron, and silicon notably reduce the electrical conductivity, while cadmium and zinc have a minimal impact. The brass referred to here must be extremely pure, containing over 99.95% copper. Even small amounts of impurities, particularly phosphorus, arsenic, and aluminum, can greatly decrease copper's conductivity. Oxygen content in copper (easily mixed in during copper smelting) greatly affects conductivity, so copper used in the electrical industry is typically oxygen-free. Additionally, impurities like lead, antimony, and bismuth prevent copper crystals from bonding, causing thermal brittleness and affecting the processing of pure copper. This highly pure copper is usually refined through electrolysis: impure copper (also known as粗铜) is used as the anode, pure copper as the cathode, with a copper sulfate solution as the electrolyte. As current passes through, impure copper on the anode gradually melts, and pure copper gradually precipitates on the cathode. The refined copper obtained this way can reach a purity of...
