PerforMet™Alloy Piston Rings High Thermal Conductivity Improve Engine Performance

Piston DiagramMaterion’s PerforMet alloy, a new piston ring material, has high thermal conductivity to manage heat buildup in the piston better than conventional piston ring materials. We manufacture piston rings with improved heat management to significantly reduce piston temperatures which, in turn, means reduced end-gas temperatures, improved knock resistance and enhanced engine efficiency. 

Our team of engineers can help with custom Piston Rings with advanced material specification and tight performance tolerance requirements. PerforMet piston rings have additional attributes that optimize engine performance, including:

Attribute

Benefit

Ability to function without a coating  Reduced cost; fewer failure modes
Lower modulus Improved conformability to the bore / liner
Lower coefficient of friction Reduced groove and liner wear
Coefficient of thermal expansion more nearly matching aluminum Reduced blowby derived from reduced ring groove clearances
