Machining Tungsten & Pure Tungsten - Cutting - …
Tungsten is a strong, hard, crack-sensitive metal that is usually brittle at room temperature. It requires special handling and skill beyond that necessary for most metals and alloys. It is important to remember when working with Tungsten is that it must be cut or formed at temperatures well above its transition temperature. Failure to do this may result in cracking or lamination. Care should be taken to insure …
