What is Python Scales?
Python Scales is titanium carbonitride (TiCN). Adding carbon to titanium nitride raises hardness and lowers friction versus TiN, producing a tough, highly wear-resistant layer. Crystallume PVD deposits it multilayered to manage brittleness in cutting, and it performs well on titanium and nickel-based alloys — best run with coolant.
Best for: High hardness and abrasion resistance, especially with coolant.
Key properties
- Higher hardness & lower friction than TiN
- Deposited multilayered for toughness in cutting
- Strong abrasion resistance
