Recognized among metal workers by its alloy code of C385, architectural bronze has truly made a name for itself in terms of versatility and reliability. It is made of approximately 57% copper, 40% zinc, and about 3% lead.
Excellent Physical Properties
Fabricators and sculptors adore this alloy because of its high machinability rating. When it is worked at high temperatures, such as with projects that require forging and pressing, it is elastic enough to be shaped into any form as one pleases. This is why artists can bend and shape this bronze into flowers, leaves, vines, and more. Aside from that, C385 is resistant to the effects of industrial and marine atmospheres. It will not corrode easily when it comes in contact with weak acids, thus making it ideal for outdoor decorations.
What Should Be Avoided
Though it is a very resilient copper alloy, architectural bronze still exhibits physical limitations. For instance, if this metal is to be used on outdoor structures like monuments, gates, posts, and the like, care should be taken against exposure to acid rain and bird droppings. For indoor installations of bronze, such as stair rails, door knobs, and similar, avoid using ammonia-containing products when cleaning them.
Should you need more data about the strengths and limitations of bronze bars, sheets, tubing, or other forms of brass, don’t hesitate to reach out to experts. These metal suppliers possess years of experience in providing their clients the right types of alloys that best fit their needs. Whatever size or gauge you require, they will most certainly have it in stock.
