The most common applications for metallic antimony are in alloys with lead and tin, which have improved properties for solders, bullets, and plain bearings. It improves the rigidity of lead-alloy plates in lead–acid batteries. Antimony trioxide is a prominent additive for halogen-containing flame retardants.
Pewter (/ ˈ p juː t ər /) is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. [1] In the past, it was an alloy of tin and lead, but most modern pewter, in order to prevent lead poisoning, is not made with lead.
Lead alloyed with a small amount of tin fills out moulds more uniformly than pure lead. Tin also increases the hardness of cast bullets up to a maximum at about eight to ten percent tin. Tin is relatively expensive, so many modern alloys rely upon antimony to increase hardness while retaining the casting advantages of a minimal addition of tin ...
Some of the main alloying elements are optionally listed after the alloy names. ... (lead, tin) Wood's metal (lead, tin ... antimony, lead; used for bearing surfaces ...
To add to the confusion, lead bore a close relation to antimony: both elements commonly occur as sulfides (galena and stibnite), often together. Pliny incorrectly wrote that stibnite would give lead on heating, instead of antimony. [161]
While there was plenty of the expected elements on the shards (four of which were glass and one of which was ceramic)—including nickel, copper, zin, tin, antimony, gold, mercury, and lead ...
A sort made from type metal. In printing, type metal refers to the metal alloys used in traditional typefounding and hot metal typesetting.Historically, type metal was an alloy of lead, tin and antimony in different proportions depending on the application, be it individual character mechanical casting for hand setting, mechanical line casting or individual character mechanical typesetting and ...
Tin is the 49th most abundant element in Earth's crust, representing 2 ppm compared with 75 ppm for zinc, 50 ppm for copper, and 14 ppm for lead. [56] Tin does not occur as the native element but must be extracted from various ores. Cassiterite (SnO
