Tin Coating Steel Isuzu Piston For Pneumatic Cylinders
4JB1 Alfin Pistons Auto Parts 8-94433-177-1
Piston Type
Steel-insert piston
Steel-insert piston allows more uniform thermal expansion and tight fitting clearance.
ALFIN piston
ALFIN is inserted within the ring grooves when casting. ALFIN is made of special austenitic cast iron. It is tightly bonded metallically to piston body and counteracts the wear in the top ring groove. ALFIN pistons are commonly used in diesel engines.
Cooling channel piston
Cooling channel pistons effectively reduce piston body working and groove land temperature under high temperature working condition.
One piece casting piston
Compared to common five-pieces casting, one piece casting technology is better in efficiency and appearance, it also reduces casting flaws.
Compares piston
The sealing and guiding functions of the piston are separated from one another. The upper part is made of cast iron and the lower part is made of aluminum. The two parts is joined by bolts. The piston can perform with not only maximum strength and heat resistance, but also low wear values and optimum conditions for meeting future emission standards.
Forged piston
The forged piston allows smaller cross sections and lower piston weight. This kind of piston is installed primarily in sports car engines and heavy-duty fast-running engines.
Piston Technology
Tin Coating
Tin is coated by electro analysis or heat dipping at thickness between 0.001 and 0.003mm. Tin is characterized as soft and oil-friendly which improves running-in efficiency of piston and liner. This coating is most commonly used.
