Stellite Jonalloy
Is a cast alloy, comprised principally of cobalt. It bridges the gap between HS ( high speed steel ) and HW ( carbide ).
The fine grain structure and physical properties makes it especially recommended and widely used for cutting operations in:
- most solid woods ( soft and medium )
( except exotics )
- metals
It also finds considerable use for wear part.
Characteristics
- Wear resistant
- Heat resistant ( until 814°C / 1497°F )
- Non-magnetic
- Rust-proof and highly corrosion-resistant
- Low coefficient of friction
- Highly resistant to shocks
