USING A BRONZE WITH VARIOUS COPPER AND ALUMINUM-BASED LEAD ELEMENTS AS BEARING MATERIAL

摘要

Use of a spray-compacted copper-aluminum bronze containing 10-16 wt.% aluminum, 1-5 wt.% iron, 1-5 wt.% manganese, 1-5 wt.% cobalt, maximum 1 wt.% silicon, lead and/or tin, and a balance of copper as a bearing material in engine construction. Preferred Features: The bronze contains (in wt.%) 14.5-15.2 aluminum, 4-5 iron, 1.8-2.3 manganese, 1.8-2.3 cobalt and a balance of copper. The alloying elements are homogeneously distributed with low segregation. The bronze has a uniform Brinell hardness over the length and cross-section in the region of HB 30 of 380-420.
