what metal can withstand the most heat
Tungsten and Tungsten alloys are often used in high temperature filaments and heater coils. Niobium is a light weight heat resistant metal. The hardest material known is still Diamond (Mohs Hardness 10) Tungsten Carbide is one of the hardest and most durable metal alloys, Mohs 9. There are forms of Carbon Steel that do very well for strength and hardness.
Maraging steel is a member of the super-strong steel family. It is an alloyâa mixture of metalsâthat is heat-treated, a process that makes it very hard and tough. Maraging steel also has the ability to withstand pulling forces, or tension (tensile strength). It can absorb a lot of energy before it deforms.
There are also alloys which are  very corrosion resistant, such as stainlessâ¦ steel. Naturally  occurring corrosion resistant metals include aluminum, gold, and  titanium, with gold and titanium being the most corrosion  resistant.
