Monel

Monel is a family of nickel-copper alloys known for their excellent corrosion resistance and good mechanical strength.

Monel 400

• Composition: ~67% Ni, 28–30% Cu, small amounts of Fe, Mn, C
• Properties: Excellent corrosion resistance in seawater and chemical environments, good mechanical strength

2. Monel K-500

• Composition: Similar to Monel 400, but with aluminum and titanium additions
• Properties: Higher strength and hardness due to age-hardening capability, retains corrosion resistance

3. Monel R-405

• Composition: Modified version for improved corrosion resistance in acidic environments
• Properties: Resistant to stress corrosion cracking and high-temperature corrosion
