The melting point of bronze alloys vary depending on the ratio of copper to other metals. The range of melting point temperatures ranges from 1,190 to 1,675 degrees Fahrenheit. Metals such as aluminum, manganese, tin, arsenic and lead are combined to form different bronze alloys.
The alloy of copper and zinc is historically referred to as brass instead of bronze. The discovery of an alloying another metal with copper to create a more durable material during the Chalcolithic period was a revolutionary technological improvement. The earliest known bronze items have been dated to 4500 B.C., originating in Serbia. Other sites in Iran and Iraq have yielded bronze artifacts that are at least five centuries younger.
