Characteristics GG25 is the most common flake cast iron grade. It offers a good combination of strength and wear resistance. It is recommended for uses where a balance is required between mechanical and characteristics and machinability. Cast iron with flake graphite, predominant pearlitic structure. Heat treatment is not recommended.

Characteristics GGG40 is the most common used nodular cast iron. Nodular cast iron has predominately a ferritic structure. Offers superior machinability combined with optimal impact, fatigue, electrical conductivity and magnetic permeability. For use beneath 0°C on a special grade (GGG40.3 or EN-GJC400-18-LT) can be produced with a very high impact test value.
