Monel® Alloy K 500

Monel® Alloy K 500 is a nickel-copper super alloy with characteristics and corrosion resistance same as the Monel® Alloy 400. Due to the addition of aluminum and titanium Monel® Alloy K 500 offers greater strength and hardness than Monel® Alloy 400. In age-hardened condition, it has greater possibility towards stress corrosion cracking in some environments.
