High-Strength Monel K500 Sheets – Perfect for Extreme Conditions

Monel K500 sheets are high-strength, nickel-copper alloy materials designed for extreme environments where corrosion resistance, durability, and mechanical strength are essential. Combining the exceptional corrosion resistance of Monel 400 with added strength and hardness from aluminum and titanium precipitation hardening, Monel K500 sheets are widely used in marine, aerospace, chemical processing, and oil & gas industries.

Material Overview – Monel K500 (UNS N05500)

Monel K500 is a nickel-based alloy with enhanced properties due to the addition of aluminum (Al) and titanium (Ti), which significantly improve mechanical strength, wear resistance, and hardness through an age-hardening process.

Chemical Composition of Monel K500

• Nickel (Ni): 63.0% min
• Copper (Cu): 27.0-33.0%
• Aluminum (Al): 2.30-3.15%
• Titanium (Ti): 0.35-0.85%
• Iron (Fe): ≤ 2.0%
• Manganese (Mn): ≤ 1.5%
• Carbon (C): ≤ 0.25%
• Silicon (Si): ≤ 0.50%
• Sulfur (S): ≤ 0.010%

Key Properties of Monel K500 Sheets

✔ High Strength & Hardness: Up to twice the strength of Monel 400 due to age-hardening treatment.
✔ Superior Corrosion Resistance: Outstanding resistance to seawater, acidic, and alkaline environments.
✔ Excellent Wear & Erosion Resistance: Ideal for high-stress applications in harsh industrial conditions.
