Tungsten can be very difficult to fabricate because of its high hardness and low ductility. 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 that the metal remains at this temperature throughout the entire forming process. The use of cold tooling which rapidly chills the metal can be as harmful as not preheating the material. The best method for machining that involves metal removal is E.D.M. The following conventional methods can also be used with great care: Grinding, forming, joining, milling, riveting, spinning, stamping, and turning.
|Cutting Speed||132 ft per minute|
|Grinding (Use aluminum oxide or silicon carbide wheels with medium hardness.)|
|Wheel Type||silicon carbide; hardness j to l ; gram size 100-120|
|Speed||12 ft per second|
|Milling (When milling Tungsten, the following is recommended)|
|Cutting speed||73 feet per minute|
|Forming (When spinning, bending or stamping note the following)|
|Temperature||1000° – 1500° F|
