Advanced Materials Laboratory

We create unique metallic and inorganic materials through process innovation using our original ultra-high pressure and powder metallurgy technologies. We contribute to the expansion of our business in industrial materials and other business fields through the development of highly functional materials and parts including cemented carbide cutting tools, diamonds, ceramics, sintered ferrous alloy parts, and special steel wires.

Powder metallurgy

We have developed cemented carbide and cermet for cutting tools and sintered ferrous alloy and aluminum alloy parts for automobiles. We are now working on the development of magnetic materials (magnetic cores and magnets) and related products which contribute to the higher performance of motors and sensors.

Ultra-high pressure technologies

We have developed a sintered diamond, a sintered CBN (cubic boron nitride) as well as a synthesized single crystal diamond employing our high pressure techniques. We are now working on the development of nano-polycrystalline diamond and applied products, which consist of nano-sized crystals and are harder than natural diamond.
