P-Series TriMetal Construction:

• Steel-backed foundation for rigidity and dimensional stability
• Intermediate copper-lead alloy layer for load-bearing strength
• Electroplated lead-tin-copper overlay for superior surface conformability and wear-in characteristics
• TriMetal design has been the industry standard since the original patent on the cast copper-lead composition
