WHY BRONZE

What Is Bronze?


To understand what bronze is, we need to understand what an alloy is. An alloy is a metal made by combining two or more other metals. Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminum, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility, or machinability. The archaeological period where bronze was the hardest metal in widespread use is known as the Bronze Age. In the ancient Near East, this began with the rise of Sumer in the 4th millennium BC, with India and China starting to use bronze around the same time; everywhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BC and reaching most of Eurasia by about 500 BC, though bronze continued to be much more widely used than it is in modern times.

Silicon bronze is a low-lead brass alloy that is generally composed of 96 percent copper. The remainder can be made from silicon and a variety of other alloys such as manganese, tin, iron, or zinc. Silicon Bronze is known for its easy pouring ability, appealing surface finish and superior corrosion resistant properties, even when submerged in liquids and chemicals. Silicon Bronze was originally developed for the chemical industry in the early 20th century and later expanded due to its good casting characteristics.
