ZINC ALLOYS FOR ELECTROCHEMICAL BATTERY CANS

摘要

(A) Zinc alloys, for electrochemical cell housings, contain apart from zinc and impurities, 0.05-0.8% Pb and (i) 0.005-1% Al + 0.0005-0.1% rare earth metal(s), (ii) 0.005-1% Mn or (iii) 0.005-1.5% Al+ rare earth metal(s) + Mn. (B) Also claimed are (a) a cast part of one of the Zn alloys, for forming into an electrochemical cell housing; (b) rolled strip of one of the Zn alloys, for punching into blanks; (c) a blank of one of the Zn alloys, for extruding to a cell housing; and (d) an electrochemical cell housing made of one of the Zn alloys.
