C38000 low-leaded architectural bronze is a wrought alloy that works well in architectural applications. While called bronze, the alloy is brass with a rich, golden luster that heightens the looks of a building's interior and exterior. It resists corrosion well when not used in marine applications.
C38000 is commonly used for architecture and builders' hardware. Specific applications include:
Diversified Bronze has solid and cored bronze bars and other shapes available. Talk with a representative to discuss your specific needs.
C38000 is made up of 55-60% copper, 36.35-43.5% zinc, 1.5-2.5% lead, 0.5% aluminum, 0.35% iron, and 0.3% tin. The best welding techniques include:
