High Temp Alloys
In general, high temperature alloys, or superalloys/hi-temp alloys, are metals intended to sustain their strength well above room temperatures and function between 500°F and 2200°F. High temp alloys offer surface stability, environmental endurance, and resistance to oxidation. They use hi temp alloys, for example, in manufacturing boiler drums, tubing for water boilers, pumps, pressure vessels, collectors, aircraft engines, and high-temperature turbines. Of all the hi temp alloys, tungsten holds the highest melting point at 3,422°C. This equates to 6,192°F. Rhenium alloys with tungsten to improve its high temperature strength and corrosion resistance. When electric arcs are needed, thorium is used as an alloying compound.
