So you know a lot more about metals than I do. I wouldn't have caught that at all: Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability. https://en.wikipedia.org/wiki/Bronze https://en.wikipedia.org/wiki/Bronze
