Materials
Granite
The granite is used because of the following qualities:
- Dimensional stability: material free of internal tension
- Thermal stability: coefficient of linear expansion is much lower than for cast iron and steel
- Resistance to wear: the hardness guarantees durability
- Hardness: similar to tempered steel
- Acid resistant
- Nonmagnetic
- Electrical insulation
- Resistant to oxidization: rustproof, noncorrosive
