ABSTRACT:
The present invention relates to copper-silicon-tin alloys having improved cleanability. These alloys consist essentially of from about 1.0% to about 5.0% tin, from about 1.0% to about 4.5% silicon, an element selected from the group consisting of from about 0.05% to about 0.5% magnesium and from about 0.01% to about 0.5% lithium, and the balance essentially copper. The alloys may also contain from about 0.01% to about 0.45% chromium.
