COPPER ALLOY AND METHOD FOR PRODUCTION THEREOF |
摘要 |
<p>A copper alloy, having Sn 3.0 to 13.0 mass%, with the balance being Cu and unavoidable impurities, which copper alloy contains crystal grains whose diameter is 1.0 to 2.0 µm, and wherein the copper alloy has a precipitate X having a diameter of 1 to 50 nm and a density of 10 6 to 10 10 per mm 2 , and a precipitate Y having a diameter of 50 to 500 nm and a density of 10 4 to 10 8 per mm 2 ; and a method of producing the copper alloy, including the steps of: cold-working the recrystallized structure with an average crystal grain diameter of 1 to 15 µm at a working ratio of 40 to 70%; and heating the resultant to obtain a recrystallized structure with a crystal grain diameter of 1 to 2 µm.</p> |
