Tungsten alloy is a material having
difficulty in machining, especially cutting, so its machining is limited to
grinding by use of a diamond wheel, etc. or electro-discharge machining.
Although tungsten alloy mainly consists of tungsten, one of the hardest
materials, it can be machined with a cemented carbide tool. Tungsten alloy
shielding can be machined into various shapes by milling, end-milling, tapping,
etc.
