TP1 copper is a specific designation used in Chinese standards, specifically GB/T 8890-2018, and it corresponds to a high-purity copper material. Here are the key details about TP1 copper bar:

Composition: TP1 copper is characterized by its high purity, typically with a copper content of 99.95% or higher. It contains minimal amounts of impurities, ensuring excellent electrical and thermal conductivity.

Properties:

1. High Electrical Conductivity: TP1 copper exhibits exceptional electrical conductivity, making it suitable for applications where efficient electrical transmission is crucial.

2. Good Thermal Conductivity: It also possesses good thermal conductivity, which is beneficial in heat transfer applications.

3. Corrosion Resistance: TP1 copper has good resistance to corrosion in various environments, although not as high as oxygen-free copper (OFC) due to its slightly higher impurity content compared to OFC grades.

4. Machinability: It is relatively easy to machine and fabricate into different shapes and components.

5. Non-Magnetic: TP1 copper is non-magnetic, which can be advantageous in certain applications.

Applications:

1. Electrical and Electronics: TP1 copper is used in electrical wiring, bus bars, connectors, and other components where high electrical conductivity is essential.

2. Heat Transfer: It finds applications in heat exchangers, HVAC systems, radiators, and other thermal management applications.

3. Industrial: TP1 copper is utilized in various industrial sectors, including plumbing, roofing, and equipment where corrosion resistance and high conductivity are required.

4. Art and Craftsmanship: Its purity and workability make TP1 copper suitable for decorative applications, sculptures, jewelry, and architectural elements.

Standards: TP1 copper complies with Chinese national standards (GB/T 8890-2018), which specify the chemical composition, mechanical properties, and manufacturing requirements for high-purity copper materials.
