Cast Iron (GG25, GGG40, GGG60)

Cast iron refers to a group of iron alloys that have a high percentage of carbon (> 2 %) and silicon (> 1.5 %) as well as e.g. manganese, chrome or nickel. Grey iron contains carbon in the form of graphite.  

Cast iron with flake graphite (GGL/GJL) 

The graphite structure defined as lamellar graphite determines the characteristic properties of this material group e.g. strength, machinability, wear resistance, damping characteristics, heat conductivity, etc. 

Cast iron with spheroidal graphite (GGG/GJS) 

Due to the spherical formation of the graphite, the ductile cast iron acquires special properties compared to the flake graphite; tensile strength, yield strength and E-module are improved, expansion and impact strength are increased.

Machining allowance

 For a perfect surface you need to calculate with minimum machining allowance which you can find in the frames below:

Base size diameter Minimum machining allowance on diameter
up to 100 mm 5-8 mm
up to 200 mm 8-12 mm
up to 350 mm 15-16 mm
up to 500 mm 16-20 mm

The spread of the machining allowances is result of different factory standards and is not part of the european standards.
