| Tellurium Copper Tellurium Copper has become the recognized material for use where high electrical conductivity must be combined with machinability. |
|
| The
normal tellurium content of about 0.5% the properties of the alloy arevery similar to
those of pure copper, but the machinability is comparable with that of free cutting brass.
It is, however, more resistant to corrosion and has, therefore, successfully replaced
brass for machine parts and fittings in mines and similar corrosive environments.
Tellurium copper is specially suitable for the manufacture of electrical instruments and
equipments where accuracy of machined dimensions, good surface and freedom from burrs are
primary considerations. Data Sheet:
