ALLOY K500 is a Ni-Cu alloy with age-hardening properties imparted by alloying additions of aluminium and titanium. Its basic composition is similar to that of ALLOY400 but the alloying additions make it age hardenable under
controlled conditions of temperature and time.

Characteristics of ALLOY K500

  • excellent corrosion resistance in an extensive range of natural and chemical environments
  • excellent resistance to chloride-ion stress-corrosion cracking
  • very high strength and hardness After age-hardening

Alloy K-500 has approximately twice the tensile strength and triple the yield strength of Alloy 400. The strength of Alloy K-500 is maintained to 1200 degrees Fahrenheit, but stays ductile and tough down to temperatures of -400 degrees Fahrenheit. Alloy K-500 also stays non-magnetic to -200 degrees Fahrenheit.
Additional characteristics of Alloy K-500 include outstanding corrosion resistance in a wide range of chemical and marine surroundings, from salts and alkalis, non-oxidizing acids to pure water. Alloy K-500 is non-magnetic and spark resistant. It is also recommended that Alloy K-500 be annealed when it is welded and that any weldments be stress relieved prior to aging.
