Pistons are produced from cast or forged, high-temperature resistant aluminum silicon alloys. There are three basic types of aluminium piston alloys. The standard piston alloy is a eutectic Al-12%Si alloy containing in addition approx. 1% each of Cu, Ni and Mg.
Why are engine pistons made of Aluminium alloys?
Solution(By Examveda Team) Engine pistons are usually made of aluminium alloy because it Is lighter Aluminium alloy are used because they are lighter.
Which aluminium alloy is used for casting?
The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4.0–13%) contribute to give good casting characteristics.
Are all pistons aluminum?
All modern engine pistons are made from an aluminum alloy. The alloy behaves somewhat differently under use according to how the piston is made, so an understanding of the manufacturing process is important.
Which cycle is mostly used in high compression engines?
In such a case, a better approach for modelling the situation will be to assume heat addition initially at constant volume and then at constant pressure. That is why dual combustion cycle is used.
How is piston manufactured?
Process of Manufacture : The majority of pistons are produced by gravity die casting process. Forged Pistons : They are made from higher strength aluminum alloy billets which are pressed into their basic shape rather than poured.
What material are motorcycle pistons made from?
Materials that are most commonly used for manufacturing pistons include: cast iron, alloy steel and aluminium alloys, aluminium- silicon (Al-Si) alloys and aluminium-copper (Al-Cu) alloys. Aluminium alloys are distinguished by good formability during casting and good machinability (machine cutting).
How is aluminum cast for hi performance pistons?
Casting aluminum for today’s Hi-Performance pistons is a demanding science. All castings are cast on Semi Automatic & Fully Automated die casting machine in multipart permanent steel molds. Melts are subject to modification, nucleation, degassing, etc. using FOSECO fluxes. Melt preparation varies from different alloys.

How are pistons graded in cast and alloys?
The pistons are subject to visual inspection and grading as per customers requirements. The pistons are graded for size and weight as specified by the customer. The pistons are colours coded or sizes engraved on the pistons crown for clear identification at the time of assembly at the customers end.
What kind of machine is used to cast aluminum?
Strict compliance to national and international standards of aluminum alloys is maintained prior to accepting the raw material. Casting aluminum for today’s Hi-Performance pistons is a demanding science. All castings are cast on Semi Automatic & Fully Automated die casting machine in multipart permanent steel molds.
