Commonly used base materials for Die Castings for Faucet Hardware include zinc alloy, aluminum alloy, and copper alloy, which are selected according to specific application scenarios and requirements:
Zinc alloy: It is cost-effective, easy to die-cast, and has good surface processability, making it suitable for mid-to-low-end faucet bodies or handles. However, its corrosion resistance is average, so surface anti-corrosion treatment is required.
Aluminum alloy: It is lightweight, has better water resistance than zinc alloy, and exhibits good fluidity during die-casting. It is suitable for faucets where light weight is a priority (e.g., bathtub faucets). However, its strength is relatively low, so a reasonable wall thickness design is necessary.
Copper alloy: It has excellent corrosion resistance and high strength, and also possesses a natural metallic texture. It is used for high-end faucets or parts that bear pressure for a long time (e.g., water inlets). However, it has a high cost and is slightly more difficult to die-cast.
For daily household use, zinc alloy or aluminum alloy is sufficient to meet basic needs; for high-end scenarios or applications with strict water quality requirements, copper alloy is the preferred choice.
