Bronze Age took place over 5,000 years ago, but the metal bronze is still widely used for so many applications today. Bronze is still a material of choice for making statues and decorative features, but there is also a growing market for architectural bronzes, especially the bronze tube. It started back in the Middle Ages when bronze was commonly used for door and window frames. It may have gone out of fashion for a while, but architectural bronze has recently made a comeback.
Composition of Architectural Bronzes
In general, bronze tubes contain a mix of different metals with varying compositions. The secret to pieces used for architecture is the right composition of approximately 57% copper, 40% zinc, and around 3% of lead. This is the only type of bronze in the market that contains a high level of lead, which is why some people call architectural bronzes as “leaded brass”.
Compared to the other types of bronzes–statuary (97% copper) and commercial (90% copper) bronzes–architectural bronze has the least amount of copper. This also means that this type is more resistant to corrosion, has a polished “pink tin” that lasts longer, and is structurally stronger than the other types of bronze on the market.
