Monel is a high-performance nickel-copper alloy known for its excellent resistance to corrosion, especially in marine and chemical environments. Composed primarily of nickel (up to 67%) and copper, Monel offers outstanding strength, toughness, and durability, even at high temperatures and under extreme conditions. The most common grades, Monel 400 and Monel K500, are widely used in industries such as Oil & Gas, Marine, Chemical Processing, Aerospace, and Power Generation. Monel is ideal for manufacturing elbows, tees, reducers, caps, flanges (ASTM B564), fasteners (ASTM B164), and bolts & nuts, making it a preferred choice for critical applications where corrosion resistance and reliability are essential.
