What Is Commercial Bronze?
C22000 or 220 bronze, most commonly called commercial bronze, is a copper alloy composed of 90% copper and 10% zinc. Available in sheets and plates, this alloy has a reddish color due to its high copper content.
The composition of commercial bronze gives this metal a more “traditional” look, as it is fairly close in ratio to early forms of bronze. The metal is still favored for its classic appearance, durability, and resistance to deterioration, making it a popular choice across many industries.
Commercial Bronze Uses
Commercial bronze is less popular than other copper alloys in the architectural industry, but it is commonly used for elevators and escalators, and sometimes in entryways. It is also a popular wrought metal, and used for fasteners, rivets, and bolts.
Bronze is also common for ornamentation, decoration, and artwork, particularly sculptures. The natural patina that it forms over time is often seen as an attractive feature of this metal, as its appearance transforms to a rich brown or even a greenish hue.
Properties
Commercial bronze has several practical properties. Chief among these is its excellent malleability, which gives it a high capacity for being cold worked. It also has good strength and hardness, corrosion resistance, and ductility.
Cleaning Bronze
If dirt and grime have marred the surface of commercial bronze, this metal can be restored and cleaned using a solution of 50% lacquer thinners and 50% water. When cleaning commercial bronze, clean only with the direction of the grain, rather than against the grain. Use a lint-free cloth to clean the surface, then rinse the metal, and finally wipe dry with another clean, lint-free cloth.
