1-Monel 400: Backed by excellent resistance to corrosion and high-strength, this nickel-copper alloy is the most popular among all Monel alloys.
2-Monel 401: It is a copper-nickel based alloy which is designed for specialized electronic applications. Plus, the Monel 401 alloy houses a low coefficient in terms of temperature resistance.
3-Monel R-405: This free-machining variant of the Alloy 400 houses controlled sulfur that acts as an efficient chip breaker while machining.
4-Monel K-500: This alloy made from nickel and copper is precipitation-hardened. It also comes with low permeability, which isn’t magnetic when kept under -150oF.
