Unwrought lead.

Containing by weight antimony as the principal other element This subheading includes lead-antimony alloys used mainly for the manufacture of accumulator plates (Pb 92 to 94 %, Sb 6 to 8 %) and ternary alloys (lead-antimony-tin) in which the weight of antimony exceeds that of tin, used for printing type (Pb 55 to 88 %, Sb 10 to 30 %, Sn 2 to 25 %). Antimony makes lead harder and more brittle.

Other This subheading includes: 1.  lead-tin-antimony alloys with up to 20 % of tin and 10 % of antimony used as anti-friction alloys; 2.  lead-tin alloys used for soldering; 3.  lead-arsenic alloys (arsenic hardens lead and makes it easier to obtain spherical lead shot).
