Nickel Alloy

Commercially pure grades ( or low alloy nickel) such as Nickel 200 and Nickel 201 have excellent corrosion resistance. Nickel alloys generally contain .38% to 76% nickel. Nickel alloys such as Hastelloy, lnconel, and Wacspaloy are classified as superalloys.

Titanium Alloy

Highest strength-to-weight ratio of all metals with good corrosion resistance as well. High thermal resistance that contributes to poor ma.ch inability.

Cobalt Alloy

Generally contains .35% to 65% cobalt. Although not typically as strong as nickel alloys, they retain their strength at higher temperatures.

Tungsten Alloy

Used for high temperature applications due to its very high melting point. High strength at elevated temperatures, but tends to be brittle at low temperatures. Poor oxidation resistance.
