The following alloys, principally lead, are used for various purposes:
This contains 8 parts of bismuth, 9 of tin, and 38 to 40 of lead.
Tin, 40 parts; lead, 45 parts; copper, 15 parts.
Lead, 84 parts; antimony, 16 parts.
Lead, 86 parts; antimony, 14 parts.
Lead, 87 parts; antimony, 12 parts; copper, 1 part.
Lead, 81 parts; antimony, 14 parts; tin, 5 parts.
Lead, 73 parts; antimony, 17 parts; zinc, 10 parts.
Tin, 53 parts; lead, 43 parts; antimony, 4 parts.
Hard lead is made of lead, 84 parts; antimony, 16 parts.
Tin............... 35 parts
Lead.............. 250 parts
Copper............ 2.5 parts
Zinc............... 0.5 part
This alloy has a fine white color, and can be readily rolled into thin sheets. For that reason it is well adapted for lining tea chests and for the production of tobacco and chocolate wrappers. The copper and zinc are used in the form of fine shavings. The alloy should be immediately cast into thin plates, which can then be passed through rolls.
