1. one kind is forged copper alloy, basic composition is (by weight):

  • 1-2.5% nickel;

    The 0.5-2.0% cobalt, nickel and cobalt total content are 1.7-4.3%, nickel is 1.01;

    1 to 2.6;

    1 with the ratio of the weight percentage of cobalt;

    0.5-1.5% silicon, (Ni+Co)/weight ratio of Si is 3.5;

    1 to 6;

    1;

    Maximum 0.025% zinc;

    Maximum 0.08% chromium;
