Description
AS-352 DZR Brass is a copper-zinc alloy with arsenic and lead additions, designed for applications where resistance to dezincification is important. This makes it suitable for plumbing environments where brass components may be exposed to water and long-term service conditions.
The alloy is commonly used for rod, wire, and bar products, with H02 and O60 listed as common tempers. Typical applications include plumbers’ brass goods, plumbing fittings, and related machined brass components.
