The tooling that is built on critical and scarce raw materials (CRMs) occupies over 80 percent of the entire global tooling market just in metal cutting area. The CRM-containing tooling is divided into three major material groups: Cemented carbide, polycrystalline diamond and cBN, and tool steels, in the descending order of importance and CRM impact. Consequently, a huge consumption of tooling leads to significant use of these critical and scarce raw materials, tungsten and cobalt globally.
Flintstone2020 aims to provide a perspective for the replacement of two important CRMs – tungsten (W) and cobalt (Co) – which are the main constituents for two important classes of hard materials (cemented carbides/WC-Co, and PCD/diamond-Co), by developing innovative alternative solutions for tooling operating under extreme conditions in the following application areas:
1. Machining ferritic and perlitic materials (steels and irons);
2. Machining austenitic materials (stainless steels and superalloys);
3. Machining titanium alloys and other special materials (composite materials);
4. Machining martensitic materials (hardened steels);
5. Cutting and processing rock and concrete.
