The term “bronze” should be understood as a raw of several double or multicomponent alloys based on copper, where tin, manganese, aluminum or other element are used as main alloying element. Due to this reason bronze can be called a tin bronze, manganese bronze, aluminum bronze, etc. However an alloy of copper and zinc (brass) or nickel can not be called a bronze.
Tin bronze is the most famous type. This alloy is one of the first explored by humans. Bronze has a much greater hardness compared to pure copper; it is strong enough and melts at lower temperatures. Tin in all grades of tin bronze is the main alloying element and its content is second in terms of volume after copper. In modern bronze additives like plumb, zinc, arsenic and other take the third place. Tin bronze except stamps with low tin content is difficult to pressure, in particular, forging, stamping, rolling, cutting and grinding. Therefore in general bronze is a casting metal which allows using it in complex by configuration castings including artistic casting - so these qualities are not inferior to any other metal.
Tin bronze is widely used in the production of bells, in numerous variations of interior antique design items, furniture, accessories, sculptures and monuments. Until the XIX century bronze was also used for casting cannon weapons, the so-called "gunmetal".
