1) Titanium (Ti) - Often described as a "sponge" due to the porosity within its structure and on its surface during formation. Titanium alloys have high corrosion resistance, are very tough, can withstand high temperatures, and have a high tensile strength-to-weight ratio. They are easy to weld, manufacture and are very effective in challenging industrial applications.
2) Tungsten (W) - a steel-gray or silver-white refractory metal. Tungsten has hardness, high temperature resistance, and can be used as a base metal or support element for alloys.
3) Stainless Steel alloy - Stainless steel, an alloy family known for its corrosion resistance and high temperature resistance, is an iron-based alloy containing 10.5% or more chromium and other elements such as nickel and molybdenum. Steel alloys are highly resistant to heat. The aerospace, automotive and construction industries use this material to make specific components, such as pressure vessels or boilers.
4) Niobium (Nb) - formerly known as niobium (Cb), used in steel alloys with hardness properties similar to titanium (similar to iron) and ductility similar to iron). It is usually alloyed with tungsten and has excellent heat resistance. The metal is commonly found in surgical equipment as well as jet engines and aircraft turbines.
5) Molybdenum (Mo) - Molybdenum is often used in steel alloys including stainless steel. It offers enhanced strength, durability and resistance to corrosion, wear and high temperatures. Its malleability and softness make it ideal for special mechanical and military applications.
6) Nickel (Ni) alloy - Nickel has excellent strength, is ductile and malleable, and has excellent oxidation resistance and corrosion resistance. Nickel is often used in stainless steel alloys to increase strength. Nickel alloys are some of the most heat-resistant metals.
7) Tantalum (Ta) - Tantalum has high density, melting point and acid resistance. Its surface has a layer of oxide film, corrosion resistance. This material is often combined with other metals to create superalloys.
