| Tellurium Copper | 
 | We offer tellurium copper (Copper No. C14500), which is widely used in forgings, screw machine products and parts, which requires extensive machining, high conductivity and corrosion resistance. Also applied in motor and switch parts, electrical connectors, plumbing fittings, soldering coppers, welding torch tips, transistor bases and furnace brazed articles. We make our tellurium copper in various quality standards such as CDA 145. Various properties and specifications are given below:
Nominal Chemical Composition % by weight
| Copper (incl. Silver) | Tellurium | | 99.47 | 0.55 |
