Hafnium Wire (Hf Wire) Description

Hafnium Wire (Hf Wire) has good corrosion resistance and high strength. Hafnium is a silvery ductile metal. It has almost the same chemical properties as zirconium, including corrosion-resistant. As hafnium has a great ability to shed electrons into the air and has a high melting point, it is the crucial component of the electrode in plasma cutting. Thus hafnium wire became an important consumption for metal fabrication industries. High purity hafnium wire has better durability in plasma cutting and a reliable source for low-cost high purity hafnium is important to make competitive plasma cutting 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.
