Hafnium wire is a thin, high-purity wire made from the chemical element hafnium. Hafnium is a ductile, silver-grey metal that is similar in properties to zirconium, and is often found in minerals such as zirconium silicate.
Hafnium wire is commonly used in a variety of applications, including nuclear reactors, aerospace and defense industries, and chemical processing equipment. Its high melting point, corrosion resistance, and low neutron absorption make it an ideal material for use in nuclear reactors, where it is used as a control rod material.
In aerospace and defense industries, hafnium wire is used as a coating material for rocket and missile components due to its ability to withstand high temperatures and its resistance to corrosion. It is also used in electrical and electronic applications, such as cathodes for plasma cutting torches and vacuum tubes.
