K7 performance alloys for aerospace
  • ISO composition : CuNi14Al3Fe1

Product forms

K7 is a wrought copper nickel aluminum alloy CuNi14Al3Fe1 designed for high strength and high reliability applications. It is non-magnetic and resists mechanical wear, galling and marine corrosion.

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

K7 is used within the aerospace 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 Aerospace industry stringent requirements.

K7 Key Applications in Aerospace

K7 is mainly used in Aerospace, in heavily stressed airframe components.

K7 demonstrates an outstanding resistance to metal-to-metal wear, thus being suited for landing gear bushings and bearing bushings.

K7 is also used in many other systems, such as cargo system bushings, plane doors, actuating sleeves, control surface components, on many mechanical and electromechanical components.

Its wear, corrosion, temperature and pressure resistance allow K7 to be ideal for the manufacturing of long-lasting parts with optimized TCO.

K7 other Applications

K7 is also be used on helicopters, for flap systems and bushings.

Its characteristics allow K7 to be used without any, or with limited lubrication.
