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