Monel Flat Washers - Corrosion-Resistant Nickel-Copper Alloy Washers

Monel flat washers are made from a nickel-copper alloy renowned for its exceptional corrosion resistance in seawater, hydrofluoric acid, and other aggressive chemical environments. They are the preferred choice for marine, chemical processing, and offshore applications where stainless steel is insufficient.

Superior Washer & Gasket Corp manufactures Monel washers in standard and custom sizes with ISO 9001:2015 certified quality control. Our specialty metal washer capabilities include Monel, Inconel, phosphor bronze, and other high-performance alloys-all made in the U.S.A. with material certifications available.
