Abstract: The present invention relates to a zinc wrought alloy with improved machinability as compared to known wrought alloys, as well as semifinished products, forgings, turned parts, locks, screw connections, locking cylinders, sleeves, fittings, pressed parts, pneumatic parts, hydraulic parts, mountings, valves and ball valves that comprise a zinc wrought alloy according to the invention.

Abstract: The invention is directed to a zinc powder or zinc alloy powder for alkaline batteries, which powder has a grain size distribution wherein 60 to 100 wt.-% of the particles, relative to the zinc powder or zinc alloy powder, have a diameter of from 40 to 140 ?m. The invention is also directed to an alkaline battery.

Abstract: The invention relates to zinc powders or zinc alloy powders with an inhomogeneous bulk density distribution depending on the particle size, wherein the difference of the bulk density measured according to ASTM B212 in the particle size range smaller than 75 ?m and that in the particle size range greater than 150 ?m is at least 0.5 g/cm3, and the mean bulk density of the powder, measured according to ASTM B212, ranges from 1.8 to 4.0 g/cm3. The invention is also directed to mixtures of said zinc powders or zinc alloy powders and to an alkaline battery including said powders.
