It is not an exaggeration to say that the technical capabilities of Mitsubishi Materials enable us to use aircraft safely. Our coated cemented carbide grades are used for machining engine and other components that use superalloys with heat and pressure resistance.
A superalloy is a type of difficult to cut material that is prone to damage from wear and welding during machining. Recently, tools with higher efficiency and longer lifetimes are required as the market size of the aircraft industry is expected to expand. We have developed an innovative coating technology named “Al-Rich coating” to meet this demand. This coating technology provides extremely superior wear and welding resistance for superalloy machining. As a result, we supply tools with long lifetimes and superior cutting performance to the world.
Our mission going forward is to further enhance Al-Rich coating and to supply society with coated cemented carbide grades that achieve ultralong lifetimes and ultrafast machining, excit- ing our customers. Our Al-Rich coating will contribute to the further development of the aircraft industry.

MV9005 is a product with Al-Rich coating and is the only tool for turning in the world that has adopted CVD-AlTiN coating. It shows an excellent lifetime that is around three times longer than conventional products, and is expected to enhance machining efficiency significantly as it supports high- speed machining.
