Product Description

Tellurium Copper Core Characteristics

⚡

High Electrical and Thermal Conductivity: Tellurium copper conductivity can reach more than 90% IACS, close to the level of pure copper, while having excellent heat dissipation capacity, suitable for high-load electrical components.

⚙️

Excellent Machining Performance: The addition of tellurium significantly improves cutting performance, machining complex precision parts and reducing tool wear.

🔥

Resistance to Softening and High Temperature: The strength is still maintained in high temperature environment, and the long-term working temperature can reach 200°C or more.

🛡️

Corrosion Resistance and Oxidation Resistance: The surface forms a dense oxide film, resistant to moisture, acid and alkali environment corrosion.

Main Application Field

📍 Electronic Connector: 5G base station, new energy vehicle battery connection piece
📍 Switch Components: Relay, circuit breaker contact
📍 Welding Electrode: Resistance welding head, spot welding electrode
📍 Heat Conduction Element: Radiator substrate, semiconductor package

Why Tellurium Copper?

Compared to ordinary copper alloys, tellurium copper can reduce machining time by more than 30% in precision machining scenarios, while extending part life by 2-3 times. Its balanced cost performance meets the development trend of lightweight and efficient industrial equipment.

Frequently Asked Questions

What are the main components of copper tellurium?

Tellurium copper usually contains more than 99% copper (Cu), tellurium (Te) 0.4-0.7%, some models add phosphorus (P) to improve the deoxidation effect.

Does the electrical conductivity of copper tellurium decrease due to processing?

Through the precise temperature-controlled thermal treatment process, copper tellurium can recover more than 95% conductivity after cold processing to ensure stable performance.

What surface treatments is tellurium copper suitable for?

Support silver plating, nickel plating, passivation and other processing, it is recommended to degreasing and pickling before pretreatment to improve adhesion.

How to distinguish copper tellurium from copper chromium zirconium?

Tellurium copper has better cutting ability and lower cost, while chromium zirconium copper (CuCrZr) focuses on high-strength wear resistance scenarios.

What is the corrosion resistance of copper tellurium?

Corrosion resistance in conventional industrial environment is better than pure copper, but strong acid and alkali environment is recommended to use with surface coating.

What parameters are required when ordering copper tellurium?

It is necessary to specify the alloy grade (such as C14500), state (hard/semi-hard), dimensional tolerance and testing standard (ASTM/GB).
