What started many years ago in the political corridors in the US, has risen as a priority project for almost all material development laboratories across the globe
Being automotive such a globalized industry, a concern that has sprung up on a specific market, can quickly become into a worldwide trend if it is properly justified by a greater good.
A clear example of it can be seen on the friction industry. What started many years ago in Washington and California, when copper considered as main cause for the extinction of salmon and rainbow trout, due to its neurotoxic behaviour in fish , has become into a priority project for almost all material development laboratories across the globe. Nevertheless, even there are still some grey areas to clarify, it is clear that the main brake system & vehicle manufacturers are already requiring copper-free formulations.
Friction industry is going on this lead but that’s not an easy job, as not a single solution has emerged as direct replacement for this material with unique properties. Engineers and friction material formulators must come up with new strategies to replace this non-ferrous metal if they want to stay on the run.
