    摘要: We provide a new copper microalloy with high-conductivity, excellent heat resistance and high strain strength, which can be obtained by conventional continuous or semi-continuous casting, which essentially consists of at least one element selected from the following list:______________________________________ 5-800 mg/Kg Pb (lead) 10-100 mg/Kg Sb (antimony) 5-1000 mg/Kg Ag (silver) 5-700 mg/Kg Sn (tin) 1-25 mg/Kg Cd (cadmium) 1-30 mg/Kg Bi (bismuth) 20-500 mg/Kg Zn (zinc) 10-400 mg/Kg Fe (iron) 15-500 mg/Kg Ni (nickel) 1-15 mg/Kg S (sulfur) ______________________________________ in all cases, with 20-500 mg/Kg O (oxygen). The alloy is suitable for all the applications that require an electrical conductivity similar to that of pure copper, but with a better heat resistance, better mechanical properties and lower standard deviation values in strain strength. Specifically, it can be used for electric wires with high mechanical requirements and/or high annealing temperatures, for high-risk applications and for electrical wires and components in the electronic and micro-electronic industry.

    摘要: A Cu-Pb system composite bearing has three layers including a backing metal, a bearing alloy layer formed on the backing metal, and an overlay formed on the bearing alloy layer. The Cu-Pb bearing alloy contains 2 to 10% Ni and 0.05 to 1.0% B. An example of the composition of the Cu-Pb system bearing alloy consists of 0.5 to 8% Sn, 15 to 30% Pb, 0.2% or less P, 2 to 10% Ni, 0.05 to 1.0% B and the balance of Cu and unavoidable impurities. The Cu-Pb bearing alloy must have a hardness over HV80. Ni and B contained in the bearing alloy decrease the affinity of the Cu-Pb bearing alloy for tin in the overlay of a tin-containing lead alloy. The corrosion resistance of the bearing is improved by plating the both surfaces of the composite bearing with Sn, Pb or an alloy thereof.
