K5 & K5B special Copper-Nickel-Aluminium alloys

CuNi14Al2, CuNi14Mn4Al3

K5 is a wrought copper nickel aluminium CuNi14Al2/ CuNi14Al3 (NFL14-702) 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.
