| Suggestions for processing : The best relation of the rates of feed for drilling and turning are between 0.1 and 0.5 mm/n. For milling the value per cutter is between 0.05 and 0.1 mm Cutting tools are recommended, which are used for
short chip breaking materials |

disadvantages |
| ++ high-tensile material ++ continuous high stability - even in the centre of thick plates ++ very good cutting quality ++ to erode (copper-electrode) + anodic oxidation for protection, + to nickel-plate chemically, + to coat galvanization |
- low corrosion - resisting - internal stresses (warping possible) - welding, soldering |
|
|
Explanation : ++ = very good, + = good to sufficient, - = not suitable |
