| 摘要 |
The invention relates to a lubricant-compatible copper alloy comprising, in weight percentages: 54-65% copper, 2.5-5.0% aluminium, 1.0-3.0% silicon, 2.0-4.0% nickel, 0.1-1-5% iron, ≤ 1.5% manganese, ≤ 1.5% tin, ≤ 1.5% chrome, and ≤ 0.8% lead, the remainder being zinc along with unavoidable further impurities, free silicon being present with at least 0.4% in the alloy matrix or in silicon-containing non-silicide phases. A method for producing such a copper alloy comprises a thermal treatment step that is carried out such that the proportion of free silicon in the matrix or in silicon-containing non-silicide phases corresponds to at least 0.4%. The invention also relates to a gear comprising at least one gear component produced from such a copper alloy. |
