What is architectural bronze?
The term Architectural Bronze describes a metal alloy of copper, zinc and various other metals that contribute various qualities to the mix. The high proportion of the copper constituent imparts corrosion resistance and durability and the addition of manganese contributes tensile strength.
Does bronze have iron in it?
Aluminum bronze contains copper, around 6 to 12% aluminum, and sometimes other additions such as iron, nickel, manganese, and silicon. It is a high strength, corrosion-resistant, and tarnish-resistant alloy.
How can you tell real bronze?

What is the difference between 360 and 385 brass?
Alloy 385, more commonly known as architectural bronze, is often found in brass angles. It is often compared to Alloy 360 (also known as free cutting brass). The key difference here is that architectural bronze has les lead in it. The unique blend of metals makes architectural bronze good at resisting corrosion.
