Abstract Wieland C24000, also known as low brass, is an 80Cu-20Zn alloy. Low brass, named for its relatively low zinc content, is a choice of many design engineers for applications where strength and formability are required. Due to its higher zinc content (compared to red brass), low brass develops a beautiful antique brass color when chemically treated, making it ideal for many decorative or architectural applications. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on corrosion resistance as well as casting and heat treating. Filing Code: Cu-927. Producer or source: Wieland Rolled Products NA (formerly Olin Brass).
