C14500 Tellurium Copper (Deoxidized Grades) has applications in the production of hot forged products, high-speed screw machine products and parts requiring high conductivity, extensive machining, corrosion resistance, copper colour, or a combination of these. The addition of tellurium enhances the strength of the copper alloy and assists in chip breakage, allowing for much higher machining speeds and ultimately longer tool life than with pure copper in high-speed screw machines.

Typical Applications:

• Gas cutting nozzles
• High-speed automatic screw machines
• Electrical Switches on power semiconductors
• Welding Torch tips
• Transformer & Circuit-breaker terminals
• Fasteners
• Production of hot forged products

C14700 Sulphur Copper is a free machining sulfur copper alloy. The addition of sulfur to the alloy makes copper sulphide that acts as a chip breaker and serves as the base for free machining capacity.

The properties of sulfur copper combined with the high retention of electrical and thermal conductivity values and makes the alloy suitable for various applications. The alloy can be machined at high speeds and results in less tool wearing.

The addition of phosphorus while manufacturing makes the alloy de-oxidised, which in turn provides resistance from hydrogen embrittlement. The alloy is appreciated for corrosion resistance, good formability and easy soldering.
