Bronze is an alloy consisting primarily of 88% copper and 12% tin, often with the addition of other metals (such as aluminium, manganese, nickel or zinc). Bronze has high corrosion resistance, and whilst bronze develops a patina, it does not oxidise beyond the surface. A number of ‘living’ finishes can be achieved with a Bronze ironmongery finish. Products that are intended to naturally oxidise and patina over a period of time, forming part of the characteristic of this beautiful finish.
