Sumitomo launches AC5005S for exotic alloys

Sumitomo Electric Industries, Ltd. has developed and launched a new high-efficiency turning grade AC5005S for exotic alloys such as Ni (nickel)-based heat-resistant alloys and hard-to-cut stainless steel.
Many hard-to-cut materials such as Ni (nickel) base alloys, Co (cobalt) base alloys, Ti (titanium) base alloys, which have excellent thermal and corrosion resistance, are frequently used for equipment and parts in the aircraft and medical industries, and the demand for tools capable of machining these alloys is rising year by year.

On the other hand, exotic alloys have high-temperature strength causing cutting tool edges to become very hot during cutting, resulting in shortened tool life and requiring the cutting conditions to be adjusted. To resolve these issues, the company has developed the new AC5005S grade, which realizes stable and long tool life at high-efficiency conditions 1.5× the conventional grades in exotic alloy turning.

The AC5000S Series currently comprises three grades. This series contributes to the reduction of machining costs by reducing the frequency of tool changes and tool usage through higher efficiency and longer tool life.
