AlTiN Coating Properties
AlTiN combines high surface hardness with elevated oxidation resistance, helping protect cutting tools during demanding machining operations.
Coating Color
Dark Gray
A distinctive dark finish commonly associated with high-performance AlTiN-coated cutting tools.
Surface Hardness
3,500 HV ± 200
High coating hardness helps resist abrasive wear and protect the cutting edge during demanding machining operations.
Oxidation Temperature
Up to 1,400°F
Elevated oxidation resistance supports machining operations that generate substantial heat at the cutting edge.
Applications for AlTiN Coatings
AlTiN is recommended for machining applications involving elevated cutting temperatures, hard or abrasive materials, stainless steel, and demanding continuous or interrupted cuts.
High-Speed Machining
AlTiN’s oxidation resistance makes it suitable for machining at elevated cutting speeds where substantial heat is generated at the tool-workpiece interface.
Hard Machining
High surface hardness helps protect cutting edges from abrasive wear when machining hardened and difficult workpiece materials.
Stainless-Steel Machining
AlTiN is recommended for stainless-steel machining at conventional or elevated cutting speeds where heat and tool wear are concerns.
Dry Machining
The coating’s thermal stability allows many materials to be machined without coolant when the tooling, material, and cutting conditions are appropriate.
Continuous Cutting
North Star’s nano-layer structure is suitable for operations where the cutting edge remains continuously engaged with the workpiece.
Interrupted Cutting
The nano-layer coating structure is also suited for cuts where the tool repeatedly enters and exits the workpiece.
Why Choose AlTiN Coating?
AlTiN provides a hard, thermally stable surface for cutting tools operating under high heat, abrasive wear, and demanding cutting conditions.
High Oxidation Resistance
AlTiN resists oxidation at temperatures up to approximately 1,400°F, helping the coating remain protective as cutting temperatures rise.
Exceptional Surface Hardness
A hardness of approximately 3,500 HV helps the coating resist abrasive wear and protect cutting-edge geometry.
Supports Elevated Cutting Speeds
Its thermal stability makes AlTiN appropriate for many applications using elevated speeds and feeds, subject to the tool and workpiece material.
Dry-Machining Capability
AlTiN can be used to machine many materials without coolant when the overall process and tooling conditions support dry machining.
Nano-Layer Coating Structure
North Star’s nano-layer film structure is designed to provide dependable performance across both continuous and interrupted cutting conditions.
Versatile Machining Performance
AlTiN can support drills, end mills, milling inserts, and other cutting tools used for high-speed, hard, and stainless-steel machining.
