Abstract
A method of making and the resulting metallurgical product for an apex seal design and/or opposing rubbing surface is disclosed; the seal has ingredients so that it is effective to inherently contain a lubricating film have a retrograde solubility curve so that small additions of chromium can precipitate to achieve a hardening of the matrix, and in some instances an independent graphite lubricant is admixed. A specific example of the composition is a copper-based alloy having 0.1-0.6% chromium and 0.5-1.5% by weight graphite.
