NC4 - CA18 is a wrought aluminium bronze CuAl10Ni5Fe4 (C63000, C63200, C95510, CW307G, AMS4640, AMS4880) with  very good resistance to sea-water corrosion, saline mist and oxidation.

It offers high strength, hardness, good fatigue as well as toughness and excellent resistance to wear, shock and 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 is a wrought aluminium bronze CuAl10Ni5Fe4 (BSB23, DTD197A) commonly 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.

  • Two-phase aluminium copper alloy
  • 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 is a wrought aluminium bronze CuAl11Ni5Fe5 (AMS4590, C63020, C95520, AMS4881, CW308G, AMS4590) with 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)
