Q. Bronze is an alloy of:
Answer: Copper & tin
Notes: Bronze is an alloy consisting primarily of copper, commonly with about 12% 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. It was particularly significant in antiquity so much that bronze age was named after that alloy.
