Alfin Ring
Alfin Ring is inserted in the top ring groove of the piston or in some designs the top two ring grooves are inserted with Alfin Rings.
Top ring carrier with Austenitic special Iron casted rings [Non-magnetic] popularly known as Al-Fin type , to provide high wear resistance for longer life than normal pistons. This ring groove means higher degree of wear resistant. These pistons are recommended for Heavy Duty Diesel Engines with turbo charger.
These are used in manufacturing of pistons with Ring groove inserts. These Ni Resist rings with high Nickel percentage, are cast in the piston by metallurgical bonding. This is particularly resistant to wear due to friction pounding. This is advantageous at high operating temperatures and pressures
Alfin Ring is machined from Centrifugal Casted Sleeve, There is no casting defect and blow holes in the Centrifugal Casting.
Chrome grooving is applied to these grooves and wear in the excess of 1mm can be recovered. Wear in the lower grooves is eliminated by sophisticated aluminum welding techniques, approved by LRS, followed by anodizing using the Ox grooving method.
In this way it is usually possible for all grooves to be returned to standard size.
All machining is done by CNC machines and Special Purpose
