This has lead to the use of 0.02–0.05% calcium alloys for corrosion-resistant grids. Lead–calcium alloys have been shown to require some tin to adequately recover from deep discharge. The minimum tin content has been shown by Giess to be about 0.6% tin [12]. Many of the corrosion-resistant grid alloys contain 0.5–0.7% tin.

in a variety of downstream products and industries; its key properties are its ability to harden and strengthen certain metals. During World War II, antimony was key to U.S. production of tungsten steel and the hardening of lead bullets used in combat; at the time up to 90 percent of antimony demand was fulfilled through domestic production.
1. Introduction. Antimony-based opacifiers (i.e., lead antimonate yellow and calcium antimonate white) were used from the beginnings of glass production in the Near East and Egypt around 1500 BC through into the Roman period (Turner and Rooksby, 1959).Towards the end of the Roman period (i.e., from about 4th century AD onwards), …

Antimony is alloyed with other metals such as lead to increase its hardness and strength; its primary use is in antimonial lead, which is used in grid metal for lead acid storage batteries. (1) Other uses of antimony alloys are for solder, sheet and pipe, bearing metals, castings, and type metal. (1)

Boulangerite is a sulfosalt, a segment of sulfides where the antimony acts more like a metal than a non-metal and occupies a position where it is bonded to sulfurs. Boulangerite and jamesonite have been called feather ores. A variety of boulangerite is called "plumosite" due to its plumose (feathery) habit and was thought to be a different mineral.
