Tantalum Tungsten Alloys

Oasis Materials Technology provides tantalum tungsten alloy shaped and machined product upon your request.

Category:

We provide tantalum tungsten alloy shaped and machined product upon your request.
We can provide all items by Ta-2.5W, but thin foil is not available for Ta-10W. Ta-10W has poor ductility and machinability cause the high content of tungsten.
