Tellurium Copper (also known as C14500 Copper) is a high-performance copper alloy that contains a small percentage of tellurium (typically 0.4–0.7%). This addition significantly improves the machinability of the copper while maintaining its excellent electrical and thermal conductivity. Tellurium copper is widely used in applications requiring precision machining, high conductivity, and corrosion resistance.
Key Properties
- Excellent Machinability: Tellurium enhances the alloy's machinability, making it easier to cut, drill, and shape compared to pure copper.
- High Electrical and Thermal Conductivity: Retains approximately 90% of the conductivity of pure copper, making it suitable for electrical applications.
- Corrosion Resistance: Resists corrosion in various environments, including atmospheric and mild chemical exposures.
- Good Strength and Durability: Offers better mechanical properties than pure copper, making it suitable for structural applications.
- Non-Sparking: Ideal for use in explosive or flammable environments due to its non-sparking properties.
Chemical Composition (Approximate)
Copper (Cu): 99.0–99.5%
Tellurium (Te): 0.4–0.7%
Other Elements: Trace amounts of phosphorus, iron, and lead (for improved machinability).
