- 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
GGG 60 has a structure that is predominantly pearlitic (>50%) in the core,
which makes it specially recommended for applications requiring high
resistance to wear and maximum strength.
The average hardness values fall within the range 200-260 HB.
