C63000, AMS4590 and other Aluminium Bronzes

CuAl10Ni5Fe4, CuAl11Ni5Fe5

NC4 / CA18 : CuAl10Ni5Fe4 (C63000, C63200, C95510, CW307G, AMS4640, AMS4880) wrought aluminium bronze

It offers very good resistance to sea-water corrosion, saline mist and oxidation, also high strength, hardness, good fatigue as well as toughness and excellent resistance to wear, shock, abrasion.

C63000/ AMS4640 is commonly used in the Aerospace industry for landing gear bushes and bearings but also in Marine industry for distributor bodies, screws, forged parts.

CA104 / CA1 / CA2 : CuAl10Ni5Fe4 (BSB23, DTD197A) two-phase, wrought aluminium copper

Widely used in the United Kingdom. Mainly used for its high strength and excellent resistance to erosion, seawater corrosion and many other aggressive environments, it offers very good wear and abrasion resistance, an ability to withstand shock loading and keeps its properties at cryogenic temperatures.

  • Transformation by extrusion, forging or die stamping

  • Suitable for hot forming (800 to 950°C). Not suitable for cold forming

  • Good behaviour at arc welding, MIG and TIG welding. Not suitable for acetylene welding and soft solder

  • Machinability: 30% free-cutting brass

NCS / CA2: CuAl11Ni5Fe5 (AMS4590, C63020, C95520, AMS4881, CW308G) wrought aluminium bronze

It exhibits high mechanical properties, oxidation resistant, saline mist corrosion resistant used in Aerospace industry (rings, bushings and bearings for landing gears, mechanical parts) but also in the Hydraulic industry (pump blocks).

Lebronze alloys manufacturing process for NC4, CA104 ans NCS is fully integrated.

Optimize your TCO!

In addition to casting and treating these materials with great quality standards and customized features on request, we also apply our large range of forming processes to these alloys:

  • Hollow bars drilling and rings cutting servces can be added for our customers convenience and/or cost optimisation
  • These aluminium bronze materials can be hot transformed with our facilities for forging & hot stamping: either to provide near-net-shape blanks to customers, or to obtain finished forgings 
  • We also offer parts machining, for instance for the Aerospace industries

We partner with customers to tailor the optimal industrial route of each component: depending on the needed design, and the respective industrial capacities of our customer in combination with our large range of processes. Near net-shape products mean more material recycling, less machining time, less machining tooling & energy: good for the economics and the environment!
