Abstract (en)
[origin: EP0384862A1] CuSn alloys partially deoxidised with Mg- or with Ca- for use in electrical and/or heat conductors. Weight composition of these alloys: - Sn content of between 200 and 1200 ppm - a residual Mg (or Ca) content lower than 10 ppm, the Mg or the Ca being in oxide form - oxygen content lower than 100 ppm - metallic impurities content lower than 40 ppm - copper constitutes the remainder. The invention also relates to a process comprising a partial deoxidation with Mg or with Ca, which enables these alloys to be obtained.
