Tellurium Copper Sheet

Product descriptions

Tellurium Copper, classified under the ASTM standard grade C14500, is a high-performance alloy that combines exceptional machinability with outstanding electrical and thermal conductivity. It also offers excellent corrosion resistance and electrical erosion resistance. This material is highly versatile, with excellent cold and hot working properties, allowing it to be forged, cast, extruded, drawn, and stamped. Tellurium copper can be processed into various forms, including plates, sheets, rods, wires, tubes, and custom-shaped profiles.

 

Tellurium Copper Sheets can be categorized based on different grades, such as brass plates, red copper plates, bronze plates, and cupronickel plates. These sheets are further divided into hot-rolled plates and cold-rolled plates. Hot-rolled plates typically range in thickness from 0.1 to 200 mm, while cold-rolled plates have thicknesses between 0.2 and 100 mm. The maximum width of these sheets can reach 2500 mm, and lengths can extend up to 6000 mm, making them suitable for a wide range of industrial applications.

 

 

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.
