Tantalum Tungsten Alloy Plate / TaW Sheet
We provide tantalum tungsten alloy plate, tantalum tungsten alloy sheet and extended tantalum tungsten rolling products.
We can provide all tantalum tungsten rolling products by Ta-2.5W, but thin tantalum tungsten foil is not available for Ta-10W. Ta-10W Alloy has poor ductility and machinability cause the high content of tungsten.
