In addition to their melting points (greater than °C), these metals exhibit excellent tensile strength, hardness, and densities, and are both electrically and heat-conducting, making them ideal. Hexonmetal is a specialized supplier of high melting metal as like Molybdenum, Zirconium, Tungsten, Hafnium, Nickel and Tantalum.

These kinds of metal is use for various fields as aerospace, automotive, Chemical process, defense and military, electronic & electrical, Titanium for biomedical, nuclear, oil and gas, thin-film Molybdenum is a less effective strengthener than tangsten as an alloding addition to tantalum.

The technology of niobium and its alloys is affected accordingly. The alloys of niobium are strengthened by dispersion- hardening and/or solid-solution mechanisms. Tungsten- and tantalum-rich alloys of the W-Ta-MoNb system were studied for   Refractory Metals.
