Question

for making bronze statues which metals are used with their proportion​

Answer 1

★The ratio of copper to tin in bronze varies depending on the application. For sculpture it is usually 90% copper and 10% tin. Bronze is resistant to corrosion, very hard and tough. Sculptors cannot work with bronze in the same way as stone.

★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.
