Description

Alloy K500 is a precipitation age hardenable nickel-copper alloy. The alloy is non magnetic to temperatures less than -101°C. The combination of low magnetic permeability, high strength and good corrosion resistance has been used to advantage in a number of applications, notably oil-well surveying equipment and electronic components. The low temperature properties of Alloy K500 are outstanding. Tensile and yield strengths increase with decrease in temperature while ductility and toughness are virtually unimpaired. No ductile-to-brittle transformation occurs even at temperatures as low as -200°C Thus the alloy is suitable for many cryogenic applications.
