Product Description
Unlike traditional ceramics that tend to be hard and brittle, Zirconia has high strength, wear resistance, and flexibility far beyond those of most other technical ceramics. Zirconia is a very strong technical ceramic with excellent properties in hardness and corrosion resistance, all without the typical property of ceramics - brittleness. Its unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics with metals like steel. Due to Zirconia's properties it is sometimes referred to as the "Ceramic steel".

Piston rings are manufactured and classified on the basis of function and usability. The primary usage of the Piston Ring is to seal the chamber (where the piston is moving), which can be a combustion chamber of a 2 stroke or a 4 stroke engine. Marine engines have three or more types of rings fitted on the circumference of the piston.
The piston ring is an essential piston part, and its numbers and functionality differ depending on the type and capacity of the engine.
In 2-stroke large engines, compression type piston rings are used to seal the combustion chamber and wiper rings are installed below them to wipe the deposits from the liner and distribute oil on the liner surface.
