GGG 40

  • Free from shrinkage, gas holes, sand and other tool wearing impurities
  • No pattern cost
  • Homogeneous and close grained structure
  • High fatigue strength
  • Exceptional dimensional stability
  • Low residual stresses

Our GGG 40 products has a ferritic structure, obtained via heat treatment
(130-190 HB), and is therefore used when machinability and a good
surface finish are the required characteristics.
Because of its ferritic structure it is recommended for uses requiring high
heat and/or electric conductivity, as well as good magnetic permeability.
GGG 40 possesses high ductility, as illustrated by its high percentage of
elongation.
