-Editor. The difference to me, as a chemist in my former life, is that bronze is mainly copper plus tin (not zinc) in various proportions, and brass is mainly a copper-zinc alloy. For example, cartridge case (brass) cents contained zinc, and thereafter both tin and zinc (like the early bronze small cents).

It may well be that any bimetallic alloy of copper with either tin or zinc might is called bronze in some circles. But I'm pretty sure that the term 'brass' should connote zinc, rather than tin, as the major component with copper (but usually along with some tin).

Brass and Bronze are metal alloys used extensively in everyday objects. While brass is an alloy of copper and zinc, bronze is an alloy consisting mainly of copper, combined most often with tin, but at times also with other metals.

Other names [edit]. Aside from cupronickel, many other terms exist which describe the same material. Still registered as tradenames are Alpaka or Alpacca' (registered trademark), Argentan Minargent, and the French term name Cuivre blanc.

Composition. Brass is any alloy of copper and zinc. Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminum, or silicon. Properties. Higher malleability than zinc or copper.

I suspect you will hear from several people about the comment in the last The E-Sylum about Copper vs Bronze vs Brass, in which Dick Johnson wrote that bronze is copper mixed with zinc. Though these metals do cause numismatists a lot of trouble, he is dead wrong about bronze and zinc.

Bronze is an ancient alloy of copper and another metallic element, tin --- not zinc. The Bronze Age was named for the widespread use of this alloy in ancient times, both in Europe and Asia. Coins and objects made bronze, when new, are reddish brown or chocolate brown in color.

Cupronickel or copper-nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese.

which describes the difference between the copper alloys bronze and brass?
Bronze is mainly copper plus tin (not zinc) in various proportions, and brass is mainly a copper-zinc alloy.
