  • High-conductivity copper microalloys obtained by conventional continuous or semi-continuous casting
    Patent number: 6103188
    Abstract: 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.
