Features and scope of application:

   TP2 phosphorus deoxidized copper has good welding performance and cold bending performance. Generally, it has no tendency of 'hydrogen disease'. It can be processed and used in a reducing atmosphere, but it is not suitable for processing and use in an oxidizing atmosphere. TP1 has less residual phosphorus than TP2, so its conductivity and thermal conductivity are higher than TP2. TP1 and TP2 are mainly used for pipe applications, and can also be supplied by plates, belts or rods and wires. Used as gasoline or gas delivery pipe, drain pipe, condensing pipe, mine pipe, condenser, evaporator, heat exchanger, train box parts.
