Solid TP1 Copper Bar

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of solid tp1 copper bar in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount solid tp1 copper bar for sale here from our factory. Customized orders are welcome.

TP1 copper bar is made from a high-purity electrolytic copper, also known as ETP copper (Electrolytic Tough Pitch Copper). Its main component is copper, going above 99.9%, and it also contains small amounts of impurity elements such as oxygen, iron and sulfur.

1. conductivity: TP1 phosphorus deoxidized copper rods have high electrical conductivity, its conductivity is higher than ordinary copper, to meet the high demand for electrical equipment conductive needs.
2. Thermal conductivity: The material also has excellent thermal conductivity, is the manufacture of radiators, heat exchangers and other thermal equipment ideal material.
3. Processing performance: TP1 phosphorus deoxidized copper rods have good processing performance, can be cut, bending, welding and other processing technology, convenient to make a variety of complex shapes of parts.

TP1 phosphorus deoxidation copper welding performance and cold bending performance is good, generally no "hydrogen disease" tendency, can be processed in a reducing atmosphere, use, but should not be processed in an oxidizing atmosphere, use.TP1 phosphorus residual amount is less than the TP2, so its electrical conductivity, thermal conductivity is higher than the TP2.TP1 and TP2 is mainly applied to the pipe, but also can be plate, strip or bar, wire supply. TP1 and TP2 are mainly used as tubes, but can also be supplied as plates, strips, rods and wires. They are used as gasoline or gas transportation pipes, drain pipes, condensate pipes, tubes, condensers, evaporators, heat exchangers, train box parts.

Q1: What does "TP1" stand for?
A: TP1 stands for Phosphorus-Deoxidized Copper, Grade 1. It is the international designation (ISO/EN) for C12000 DLP copper, indicating deoxidation with phosphorus and a low residual phosphorus content (0.004% - 0.012%) to maintain higher electrical conductivity.

Q2: What is the difference between TP1 and C11000 (ETP copper)?
A: The main difference is oxygen content. C11000 (Electrolytic Tough Pitch) contains oxygen (200-400 ppm) and is susceptible to hydrogen embrittlement when welded or brazed. TP1 is deoxidized, containing virtually no oxygen, making it safe for welding and brazing while maintaining conductivity close to C11000.

Q3: What is the electrical conductivity of TP1 copper?
A: TP1 copper offers 85% to 98% IACS (International Annealed Copper Standard), with typical values around 90% IACS. This is significantly higher than TP2 (80-85% IACS) and approaches the 100% IACS of pure C11000 copper.

Q4: Can TP1 copper be welded?
A: Yes, absolutely. TP1 is deoxidized and resistant to hydrogen embrittlement, making it suitable for gas welding, arc welding, brazing, and soldering. This is one of its key advantages over C11000 copper.

To ensure your Solid TP1 Copper Bars arrive in optimal condition, we employ rigorous packaging protocols tailored to the product form and destination. Bars are carefully sorted by size and temper, then securely bundled with heavy-duty steel straps to prevent movement during transit. Each bundle is wrapped in multiple layers of moisture-resistant kraft paper and polyethylene film, creating an effective barrier against humidity and environmental contaminants. For international shipments, we utilize seaworthy plywood crates or reinforced pallets with protective corner guards. This comprehensive packaging ensures your TP1 copper bars arrive at your facility factory-fresh and ready for production, whether for precision machining, electrical assembly, or structural fabrication.
