China Zinc Alloy Bibcock suppliers Zinc lock bibcock Zinc lock bibcock is made by zinc alloy, the price is cheaper more than brass bibcock, but the quality is not well than brass bibcock. Zinc alloy characteristics 1. Relatively significant ratio. 2. Good casting performance, can die-cast complex shape, thin-walled precision parts, smooth casting surface. 3. Surface treatment can be conducted: electroplating, spraying, painting, polishing, grinding, etc. 4. No iron absorption during melting and die-casting, no corrosion and compression type, and no adhesive mold. 5. Good room temperature mechanical performance and wear resistance. 6. Low melting point, melting at 385鈩? easy to die-cast molding.
