Refractory Metals Properties | What Makes Refractory Metals So Unique?

0 Comment

Refractory Metals Properties Refractory metals mainly include tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium and titanium. Actually, the melting point of rhenium also is extremely high, but its reserves are too rare, most used in high-temperature alloy parts of the jet engine. Among them, the most common refractory metals are tungsten, tantalum, molybdenum, niobium. In this […]
