Tantalum Tungsten Alloy

Category:

We provide tantalum tungsten alloy with shaped and machined products upon your request. All products as pure tantalum are available by Ta-2.5W, but thin foil is not available for Ta-10W. Ta-10W has poor ductility and machinability cause of the high content of tungsten.
