Characteristics of GGG40

GGG40 is the most commonly used nodular cast iron alloy and has a predominantly ferritic structure. This cast iron offers excellent machinability combined with good impact resistance, high electrical conductivity, good elongation properties and magnetic permeability. The material cannot be welded.

Because GGG40 is extremely tough, it is suitable for components that are subjected to large forces; e.g. levers, chain links, housings, brake shoes and connecting rods.
