MITSUBISHI MATERIALS CORPORATION Metalworking Solutions Company (Company President: Tetsuya Tanaka, Address: Marunouchi, Chiyoda-ku, Tokyo) has released additional inserts to the MC5100 series of coated carbide grades for cast iron turning. These new additions will go on sale on April 15^th.

MC5100 is a series of CVD coated carbide grades that supports a wide range of machining needs. There is a choice of a grade with high wear resistance, a grade for general turning of grey cast iron and a grade with excellent fracture resistance for heavy interrupted machining. 

These three grades are the MC5105, which exhibits outstanding wear resistance during high speed cutting of gray cast iron at speeds up to 1000 m/min. The MC5115 grade that suppresses abnormal cutting edge damage during ductile cast iron turning and achieves both excellent wear and fracture resistance, and the MC5125 grade that demonstrates excellent fracture resistance during heavy interrupted cutting of high-strength ductile cast iron.

Key features of the MC5100 series for cast iron turning

1. All three grades use Super nano-texture technology to achieve the industry’s highest level of crystal orientation control of the Al²O³ coating layer.
    
2. MC5105 exhibits outstanding wear resistance with a top layer of the thickest coating, combined with a high hardness carbide base material.
    
3. MC5115 achieves excellent durability with the Al²O³ layer that displays excellent abrasion resistance and also features a new adhesion layer that has improved resistance to peeling.
    
4. MC5125 has excellent stability due to the microstructure of the intermediate layer that is highly suitable for ductile cast iron. Additionally, this grade features a TiCN layer that is ideal for coping with heavy interrupted cutting.
