The tungsten alloy part contains 0.1 to 3 wt % of the Hf (hafnium) component in terms of HfC (hafnium carbide), and thereby characteristics such as emission characteristics and a strength can be improved. That is, when the content of the Hf component is less than 0.1 wt % in terms of HfC, the addition effect of the Hf component is insufficient.

Titanium carbide is the binary compound and is an extremely hard refractory ceramic material ( Mohs 9-9.5) similar to tungsten carbide. It is the only carbide in the titanium – carbon system. Like Tungsten Carbide (WC) and Tantalum Carbide (TaC), it is also an important component of cemented carbides used for cutting tools.

Tantalum carbide (TaC) and hafnium carbide (HfC) are of particular interest due to their high melting temperatures (>4000 K) which are the highest reported among all known inorganic materials 1,2,3. They are known to form a continuous solid solution over the whole range of compositions.
