ISO 513 group N (Non-ferrous metals & non-metallics): workpiece materials, grades and selection
What ISO 513 group N covers
| Group | N — Non-ferrous metals & non-metallics (identification colour: green) |
|---|---|
| Workpiece materials | Aluminium alloys, copper, brass, bronze; also plastics, composites and other non-metallics. |
| Application band | N01 (fine finishing) – N30 (roughing) |
| Grade behaviour | Low cutting temperatures, but built-up edge on soft materials and abrasive fibres in composites. Very high speeds are common. |
| Typical coating family | Often uncoated or polished; where coatings are used they are thin PVD or DLC types. Diamond coatings appear in composites. |
| Selection guidance | Choose sharp, polished edges and high rake geometries; avoid grades with additives that smear on aluminium. |
Group definition, identification colour and band numbering per ISO 513 (classification of carbides by use). Behaviour and coating notes are general engineering guidance, not manufacturer cutting data.
