A trimetal pad is made to be able to take advantage of the benefits of white metals, lead bronze.

Trimetal bearing have a sheet steel base ranging from 1 to 10 ml, a layer of lead bronze and sintered and soldered on top (can be replaced by copper lead) over 0.3 to 1.5 mm.

Copper-lead is an alloy of copper and lead, often with added tin, nickel and antimony, used as an anti-friction alloy.

A trimetal bearing is finished with a layer of white alloy, which serves as a friction metal, over 0.02 to 0.025 mm, which is protected from corrosion by an indium flash (made by electrolysis).

All trimetal bearing are shaped using a press. In the event of an accident on the trimetal bearing, the white metal melts, but the lead bronze serves to limit the damage.

Trimetallic bearing consist of a steel shell, a friction layer, a stop layer and an anti-friction layer. The anti-friction layer is usually based on lead bronze and galvanically applied. Trimetallic bearing are mainly used in engines subject to high loads such as large piston pin rings, connecting rods bearings, main bearings and crankshaft bearings.
