The Cermet owes its unique grey colour to the combination of a metallic zirconium matrix with highperformance ceramic inserts. Its implementation required a degree of rigour commensurate with that needed to create the materials themselves. Heating and pressing together very different kinds of materials at a high temperature without altering their respective qualities was a challenge.It proved even more difficult to obtain a homogeneous whole, as nickel and cobalt, which are normally used in this family of hard materials, were excluded in order to adhere to REACH standards, which ensure safety in the production and use of chemicals in the European industry.
