Oftentimes, materials in their purest forms don’t provide the exact qualities needed, cannot be easily plated or machined, or are far too expensive for an entire job. This is where the creation and use of alloy metals can be beneficial.
In the case of TeCu, Tellurium is added to the pure copper material, and it evenly fills throughout the microstructure of the copper. This precipitate causes the copper to become more easily machinable, without effecting its ductility and only slightly affecting its malleability.
Aside from pure chrome, Tellurium Copper is a far better conductor of electricity than popular copper substrates Brass and Bronze. However, it should be noted that TeCu is not as physically strong as other copper substrates like brass, bronze, and phosphor bronze. However, its softness and machinability provide the substrates with their own niche in the manufacturing industry.
