C35330 a dezincification-resistant machining brass, is particularly suitable for use in warm, acidic waters. This material passes the dezincification test according to ISO 6509. For the manufacture of hot-stamped parts C35330 with better hot-working properties is recommended. To achieve dezincification resistance a heat treatment may be necessary after hot working.
