CW724R, also known by the trade name Cuphin, is a lead-free brass alloy containing silicon (Si) and phosphorus (P). The alloy is dezincification-resistant and offers excellent corrosion resistance, making it particularly suitable for components in contact with drinking water, such as valves, fittings, and faucets.

With its combination of strength, formability, and environmentally friendly composition, CW724R serves as an ideal alternative to traditional leaded brasses. It complies with current EU regulations for lead-free materials used in plumbing, energy, and water applications.
