Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon, depending on the application. They are made using gravity cast or hydraulic forging processes, followed by heat treatment in an automatic HT implant with solubilization by quench in hot water. Machining is completed using CNC machines and diamond tools, achieving specific surface finishes for the intended application. Each piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A new Phosphate Coating is also available, offering increased hardness, light surface porosity, and superior adhesion qualities for enhanced coating durability. This product is 53.96mm with a dome head and a 0.78mm ring.
