Hafnium Wire

Hafnium (Hf) is a shiny/silvery and ductile metal that is corrosion-resistant and chemically similar to the zirconium. It is an important material in the atomic energy industry and it can be used as the cathode of the X-ray tube in the electrical industry. Hafnium wire is drawn from high-purity hafnium metal. 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. Hafnium can also be used as the adding elements in heat-resistant alloys, such as tungsten, molybdenum and tantalum alloys. We can offer the hafnium wire (Hf Wire) with various dimensions.
