Carbide cutter inserts will extend tool life. F for 30 minutes. Coolant can be used. Material also can be cut using high-speed abrasive cutoff wheels. As a result of the material's characteristics and especially its low thermal expansion, very close tolerances and fine finishes can be held.
Joint strength is close to that of parent material.
One disadvantage is that it should be done in a controlled atmosphere, which is not too practical for most users. If parts are finished, there may be some distortion from the process. Typically .002 clearance between parts to be joined is required. As the part gets larger, more clearance is required. Parts should be as clean as possible, sand blasting is sometimes used, both parts are fluxed, carefully heated until solder flows.
