Development and Sales of PCD Grade SUMIDIA™ DA1090 for Machining of Cemented Carbide, Hard Brittle Material, and Aluminum Composites

Sumitomo Electric Industries, Ltd. (Head office: Chuo-ku, Osaka, President: Osamu Inoue, hereafter "our company") has developed and launched the PCD*² Grade SUMIDIA™ DA1090 for machining of cemented carbide, hard brittle materials*¹ and aluminum composites for sale as of November 2024.

SUMIDIA™ is a PCD sintered material made by sintering diamond, the hardest material, with a binder under high pressure and high temperature. As a tool material, it can be used in a wide range of applications like machining of aluminum alloys, as well as hard-to-cut materials such as cemented carbide and hard brittle materials.

Cutting tool edges are put under heavy load when machining cemented carbide used in molds or milling of aluminum alloy and cast iron composite material used in automotive parts, as such, tool materials with higher wear and fracture resistance are required.

In response to these needs, our company has newly developed and launched the PCD grade SUMIDIA™ DA1090, which balances excellent wear resistance and fracture resistance to achieve stable performance in high-load machining.

PCD Grade SUMIDIA™ DA1090 for Machining of Cemented Carbide, Hard Brittle Material and Aluminum Composites

1. Features
SUMIDIA™ DA1090 is a grade for machining cemented carbide, hard brittle materials and aluminum composites with improved wear resistance and fracture resistance through increasing the density of the sintered structure and enhancing the bonding strength between its particles, obtained through our proprietary sintering process. This grade achieves even greater stability than conventional grades in the roughing of cemented carbide and milling of aluminum alloy and cast iron composite material.

2. Lineup
ISO Turning/Milling Inserts DA1090 37 Cat. Nos.

3. Sales Plan
120 million JPY/year in the first year, 300 million JPY/year after 3 years

4. Standard Price
8,960 to 17,900 JPY (excluding tax)/pc

*1 Hard brittle material
Materials characterized by high hardness and brittleness, such as cemented carbide, ceramics, quartz glass, zirconia and so on.

*2 PCD (polycrystalline diamond)
A material made by sintering diamond microcrystals together with metal, such as cobalt, at high temperature and high pressure.
