Monel K-500 Sheets & Plates

What are Monel K-500 Sheets & Plates?

Monel K-500 (UNS N05500) is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance of Monel 400 with enhanced strength and hardness. It is strengthened by the addition of aluminum and titanium.

Key Functions:

• Provide high strength and durability in harsh environments
• Resist corrosion in marine and chemical applications
• Perform efficiently under high stress and pressure
• Ensure long-term reliability in critical applications

Chemical Composition of Monel K-500

Typical Composition:

• Nickel (Ni): 63% – 70%
• Copper (Cu): 27% – 33%
• Aluminum (Al): 2.3% – 3.15%
• Titanium (Ti): 0.35% – 0.85%
• Iron (Fe): ≤ 2%
• Manganese (Mn): ≤ 1.5%

The addition of aluminum and titanium enables precipitation hardening, significantly improving strength.
