Inferior material: inferior copper and zinc alloy
- If made of inferior copper and zinc alloy, the faucets’ll be more vulnerable to cracks, trachoma, and other defects. The plating layer’ll be more vulnerable to pitting, blistering, and poor adhesion to the coating. The appearance of the coating is severely corroded or even the coating falls off after a period of time. What’s more, there’ll be a lot of toxic heavy metal precipitation, it’ll be harmful to the health.
High-quality material: selected 59 copper and high-grade low lead copper
- Copper is the best material for faucet manufacturing currently, almost all mainstream brands are copper faucets. The main components of a copper faucet are copper and zinc, commonly known as brass. A little of lead has to be added throughout the production of copper ingots or rods to improve the cutting performance of brass. If the faucet is completely lead-free, it won’t only have difficulties in cutting and poor casting and forging performance, but also crack after it’s made into a finished product, because of its poor stress corrosion resistance.
