Method for producing lead-containing copper alloy water supply equipment, casting de-leaded water supply equipment and water supply equipment |
| abstract |
An object of the present invention is to manufacture a lead-containing copper alloy water supply device having an excellent appearance while sufficiently reducing the amount of lead eluted into water from the inner peripheral surface of a water passage. A deleading step (S20) is performed before a cutting step (S30), in which a casting (10) is immersed in a de-leading liquid to delead the outer peripheral surface of the casting (10) and the inner peripheral surface of a water passage (10a).
