Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% Silicon, depending on the application. They are made using gravity casting or hydraulic forging, with a heat treatment process involving solubilization by quenching in hot water. Machining is done with the latest CNC machines and diamond tools to achieve specific surface finishes. Each piston undergoes rigorous quality control. Vertex pistons have a Molybdenum Bisulphite black coating for break-in and reduced friction. A new Phosphate Coating offers increased hardness, light surface porosity, and superior adhesion, extending coating durability. This piston is a replica part with a single ring, a 53.93mm bore, and is Grade B.

FULL DESCRIPTION

Vertex Grade B Single Ring Replica Piston

The Vertex Grade B 53.93mm single ring replica piston is engineered to restore engine performance and reliability. Manufactured using advanced Low-Ex (low expansion) aluminium alloys, these pistons are specifically designed to withstand the high-stress demands of high-performance engines while maintaining precise tolerances.

Advanced Manufacturing and Material Quality

Vertex utilizes a sophisticated gravity cast or hydraulic forging process to create high-strength piston blanks. The material structure is further refined through a state-of-the-art heat treatment process, which includes solubilization and a specialized water quench to ensure maximum durability and consistent material density.

Precision Engineering and Friction Reduction

Each piston is finished using precision CNC machining and industrial diamond tools to achieve an exact surface finish tailored to the application. To optimize engine efficiency and longevity, this piston features two distinct coatings:

  • Molybdenum Bisulphite Coating: A specialized black coating that assists during the initial break-in period and reduces internal friction during cylinder operation.
  • Phosphate Coating: Inspired by Formula One technology, this all-over coating increases surface hardness and provides light porosity. This improves the adhesion of the Molybdenum coating, resulting in significantly extended durability.

Key Features

  • Grade B piston specification with a 53.93mm diameter.
  • Single ring design for high-performance applications.
  • Engineered from high-quality Silicon-charged aluminium alloys.
  • Subjected to rigorous manual and automatic quality control inspections.
  • Advanced thermal treatment for superior structural integrity.
