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.
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
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)
