Modern zinc alloy wash basin faucets strike a balance of strength, durability, and affordability, making them a popular choice for many consumers. Such faucets often contain a combination of zinc, copper, and other metals. Zinc alloys are often used in faucet manufacturing because they are strong, corrosion-resistant, and easy to cast and form.

The exact composition of the zinc alloy used in a particular faucet can vary depending on the manufacturer and the specific design of the faucet. However, most modern zinc alloy faucets are made from a mix of zinc and copper, with trace amounts of other metals such as nickel, chromium, and manganese.

The percentages of zinc and copper in the alloy can vary depending on the desired strength, durability and aesthetic properties of the final product. Generally speaking, the higher the copper content, the stronger and more durable the faucet. However, higher copper content can also make the faucet more expensive.
