Characteristics of GGG40<\/h2>\n<\/div><\/div>

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.<\/p>\n

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.<\/p>\n<\/div><\/div>
