TP2 is the English abbreviation for phosphorus deoxidized copper (purple copper). It is a melting high purity raw material that can be processed and used in a reducing atmosphere, but should not be processed and used in an oxidizing atmosphere. It is commonly used for gasoline or gas delivery pipes, drain pipes, condenser pipes, pipes for water mines, condensers, evaporators, heat exchangers, and train box parts. TP2 can be processed and used in a reducing atmosphere, but should not be processed and used in an oxidizing atmosphere.TP1 has less phosphorus residue than TP2, so its electrical and thermal conductivity is higher than that of TP2.TP1 and TP2 are mainly applied as tubes, but can also be supplied as plates, strips, or rods and wires. It is used as gasoline or gas delivery pipe, drain pipe, condenser pipe, pipe for water mine, condenser, evaporator, heat exchanger, train box parts.
Phosphorus deoxidized copper is melted high purity raw materials, the oxygen produced in the melted copper with the oxygenophilic phosphorus (P) deoxidized, so that its oxygen content is reduced to less than 100PPm, thus improving its ductility, corrosion resistance, thermal conductivity, weldability, draw processing, and does not occur at high temperatures in the hydrogen embrittlement phenomenon. Phosphorus deoxidized copper can be used in refrigeration and air conditioning, heat exchangers, radiators, cylinder gaskets and many other applications.
