What is TP1/C12000 copper?
TP1/C12000 phosphorus-deoxidized copper, also known as DHP copper (Deoxidized High Phosphorus Copper), is a copper alloy characterized by the addition of phosphorus to reduce oxygen content and improve its machinability and weldability. TP1 copper possesses excellent electrical and thermal conductivity and weldability, making it widely used in the manufacture of pipes, conduits, and other related products in many fields.
The characteristics and applications of TP1 phosphorus-deoxidized copper include:
Thermal conductivity: TP1 copper's excellent thermal conductivity makes it widely used in the manufacture of radiators, cooling devices, and heat exchangers.
Weldability: Due to the addition of phosphorus, TP1 copper has a low oxygen content and good weldability. This makes it very suitable for manufacturing pipes, pipe connections, and welded components.
Refrigeration and air conditioning systems: Due to its thermal conductivity and weldability, TP1 copper is often used to manufacture condensers, evaporators, connecting pipes, and other components in refrigeration and air conditioning systems.
Plumbing systems: TP1 copper's corrosion resistance and weldability make it an ideal choice for manufacturing water pipes, fittings, and valves in plumbing systems. Industrial Equipment: TP1 copper is also used in the manufacture of industrial, chemical, and energy equipment, such as pipes, valves, and heat exchangers.
Construction Industry: TP1 copper is commonly used in the construction industry to manufacture heating systems, piping systems, and sanitary equipment.
Automotive Manufacturing: TP1 copper is used in the automotive manufacturing industry to manufacture components such as cooling systems and brake lines.
