alfin ring for piston casting

Binzhou Fudi Machinery (salt core and alfin ring)

* Usual hardness is 120-160HB
* High Wear Resistance Nickel Alloy
* According to the diameter we agree on
* Application for Gasoline and Diesel Engine Piston
Pistons with our ALFIN rings provide comparative qualities as those made in Germany, Japan and Britain.
We offer Nickel Piston Ring Carriers and those with internal cooling channel and salt core, respectively. With this new technology, the engine can run at higher speed, higher compression pressure, produce more power, but without increasing piston working temperature, thus enhance engine performance and prolong piston lifespan and reduce emission.
