Bronze, typically referring to tin bronze, is a copper-tin alloy containing approximately 88% Copper and 12% Tin by mass, and one of the oldest deliberately produced alloys in human history. It is harder and more resistant to corrosion than pure copper, casts with excellent detail reproduction, and develops a characteristic warm reddish-brown patina with age. In the modern age its primary applications are in bearings, bushings, marine hardware, bells, and statuary, where its corrosion resistance and acoustic properties remain unmatched by cheaper alternatives. However, in an age long gone, bronze was the only material from which swords, spearpoints and plate armour would have been made of.
