PerforMet™Alloy Piston Rings High Thermal Conductivity Improve Engine Performance
Materion’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:
|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|
