Flintstone 2020

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.
