K5B® is a wrought copper nickel aluminum alloy CuNi14Al3 (NES835) 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.

  • High strength & Toughness
  • Outstanding resistance to marine corrosion & erosion
  • Excellent wear resistance
  • Good anti-fouling properties
  • Good machinability
  • Excellent galling resistance especially with stainless steels
  • Good thermal properties
  • No Hydrogen embrittlement
  • Low magnetic permeability
  • Galvanic compatibility with other copper alloys and stainless steel
  • High performance at both elevated and sub-zero temperatures -193 °F up to 572 °F
  • Dimensional stability

Lebronze Alloys manufacturing process for K5B® is fully integrated: internal processes include casting, hot and cold working stage, heat treatment and non-destructive testing. Being fully integrated ensures reactivity and complete traceability.
