Olin Brass Alloy C42200 (Tradename: Lubronze) is a copper-zinc-tin alloy (tin brass). The mechanical properties and performance of C42200 are very similar to those of high-zinc brass alloys with the added benefit of improved resistance to stress relaxation. It is also a cost-effective alternative to phosphor bronze. This datasheet provides information on composition and physical properties. It also includes information on corrosion resistance as well as forming. Filing Code: Cu-904. Producer or source: Olin Brass GBC Metals, LLC.
