PURPOSE:To decrease Sb content of lead alloy and accomplish a cast product of good workmanship free from crazes by including metals in specific proportion by weight. CONSTITUTION:Lead alloy is used to a storage battery, the composition being 1.6-3.5% Sb, 0.2% or less As, 0.06-1.0% Sn, 0.002-0.08% Cu, 0.006-0.1% Se, and lead as remainder. This ensures that no casting crazes are generated even with less Sb content, and provides good performance when it is used to a battery. |
