Wholesale Monel K500 Round Bars – Factory Direct & Competitive Pricing

Introduction to Monel K500 Round Bars

Monel K500 round bars are high-performance nickel-copper alloy bars known for their exceptional strength, corrosion resistance, and durability. As an advanced variant of Monel 400, Monel K500 offers improved mechanical properties due to precipitation hardening. These bars are widely used in industries such as marine, aerospace, oil & gas, and chemical processing, where resistance to extreme environments is crucial.

Material Overview - Monel K500 (UNS N05500)

Monel K500 is a nickel-copper alloy that includes small additions of aluminum and titanium. Through age hardening, this alloy achieves superior mechanical properties while maintaining excellent resistance to corrosion in harsh environments, including seawater and chemical exposure.

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%
