The pistons are casted in permanent mold using Al-Si alloys that provide high resistance at elevated temperatures for use in petrol and diesel engines.<\/b>
\nSome pistons are made with a lamellar grey cast iron ring in correspondence of the first compression groove to limit the wear and a cooling channel (tunnel) in correspondence of the head of the piston in order to avoid an excessive overheating of the piston crown.
\nFor heavy duty application bushings may be introduced at the pin bore to support the contact pressures between the piston and the gudgeon pin.
\nTo limit the friction between piston and cylinder during operation of the engine it is possible to apply special graphite coatings on piston skirt.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>Forged Pistons<\/h2>\n
In the field of high performance engines (i.e. motorbikes, sports applications,\u2026) the modern state of art requires the use of drop-forged pistons.<\/b>
\nThese components are made with alloys obtained from the inverse extrusion of casted aluminum billets. The alloys used for these pistons are Al-Si alloys which unlike those used for casting pistons allow to achieve a finer structure which results in better mechanical properties.
\nThe use of forged pistons, in addition to allowing to obtain more resistant alloys, allows to have thinner resistant sections with a considerable advantage in terms of weight.
\nA special feature that can be employed on the forged pistons to limit the excessive wear of the first groove is the application of a coating of hard anodizing.
\nAlso in the forged pistons the application of coatings based on graphite is provided to limit the friction between piston and cylinder.<\/p>\n<\/div><\/div><\/div><\/div>![](\"https:\/\/www.duraldur.it\/wp-content\/uploads\/2018\/06\/pistoni-stampati-01.jpg\" "\\"Duraldur")

Diesel engines evolution and their related emission laws have pushed to achieve more strength engine components, pistons too. <\/b>
\nThe even more restrictive project constraints were the basis for a deep development of piston structure as generally known.
\nThe first step toward this new progress was the deployment of a steel crown piston that was introduced in the articulated piston into the diesel engine world.
