Up to 50% stronger by design and material specification
"CarbonLafer is a Tungsten carbide based multi-layered amorphous WC/C coating, suitable for any applications where it is necessary to reduce friction between mechanical components and where the objective is to reduce the use of lubricants. Its main characteristic is that it has an extremely low friction coefficient, strong adhesion and sufficient hardness to support important mechanical duties. We dont recomend to use the non treated option from Brena and dont sell it!
