The Australian market is a special one, which is a country with many coastal cities, so the corrosion resistance requirements of the metal fittings are relatively high. Generally, the copper parts used are required to be materials with anti-dezincification function.
The copper parts supplied by Tucai to the Australian market are mainly CW602N, and there are also low lead resistant copper for dezincification, such as CW511L and CW724R(please consult the sales staff for this demand).
WMK certification requires products to pass AS4020, AS2345 and AS3499 simultaneously
