K5 & K5B special Copper-Nickel-Aluminium alloys

CuNi14Mn4Al2, CuNi14Al3

  • ISO composition : CuNi14Mn4Al2, CuNi14Al3
  • Other norms : NES835 /DEF STAN 02-835, ASNA 6127A, GAM MM11, NFL 14 702

K5 - X316 is a wrought copper nickel aluminium CuNi14Al3/ CuNi14Al2 (NFL14702, ASNA 6127A, GAM MM11) with very high mechanical properties, good impact and fatigue resistance, non-sparkling on impact. It is strictly amagnetic. K5 is used for the  Aerospace industry and Electrical engineering applications. 

K5B® is a wrought copper nickel aluminum alloy CuNi14Mn4Al2 designed for high strength applications in seawater environment.

It is non-magnetic and resists mechanical wear, galling, stress relaxation, corrosion and erosion.

It is easily machined into complex components, whilst being environmentally friendly being both lead and beryllium free.

K5B® is used within the Oil & Gas industry thanks to its outstanding physical and mechanical properties in many varied components.

Lebronze alloys has developed a full range of Copper Nickel Aluminum matching the Oil & Gas industry stringent requirements.

K5B® is compliant with the norm NES835 / DEF STAN 02-835.
