Product Introduction
About this item:
As hafnium has a great ability to shed electrons into the air and has a high melting point, the main industrial application of hafnium wire is as a plasma emitter for plasma-cutting machine electrodes. West-Ti supplies the hafnium wire (Hf Wire) with various dimensions.

Applications
Used for producing superalloys
Used as solder
Used as a plasma emitter in plasma cutting
Used in plasma cutting electrode (Cut hafnium wire could be inserted into copper parts to make a cutting tip for the plasma cutter).
Recently, scientists at Intel and IBM found that hafnium-based compounds can be applied in gate insulators to make the processors even smaller.
