Monel

Monel is a group of nickel alloys that contain copper, iron, and small amounts of other elements such as manganese, silicon, and carbon. Monel alloys are known for their excellent corrosion resistance, high strength, and good mechanical properties at elevated temperatures. Here is a brief description of Monel products such as pipe, tube, flange, fastener, fittings, and round bar
