T3 Red Copper Seamless Tube With Good Electric Conduction And Heat Conduction
1. Description
T3 red copper tube has good conductivity, good heat conduction, corrosion resistance and processing performance. It can be welded and brazed. It contains less impurities to reduce conductivity and thermal conductivity. A Little oxygen has little effect on its heat conduction and machinability, but it is easy to cause "hydrogen disease", so it is not suitable for using in high temperature (such as > 370 °) reducing atmosphere machining (annealing, welding, etc.).
Our company's Red Copper seamless tube mainly include T2 ,C11000 and T3 copper tube, fin tube and U-tube. The products are produced in strict accordance with the standard, and the finished products can be tested by the third party according to the customer's requirements. These copper tubes are mainly used in power plants, desalination, petrochemical, mechanical ships and automotive heat exchangers. We have rich production experience, professional technology, excellent equipment, superior quality, reasonable price, high-quality service, so that our products sell well all over the world, well received by customers.
