Thermostatic faucets are commonly used faucets at home. Generally speaking, the main body of the faucet is brass. The quality of electroplating with brass faucets is the best guarantee. Consumers can use the method of estimated weight to identify when purchasing, brass is heavier and harder, and zinc alloy is lighter and softer. The quality of the faucet should not be judged by weight alone, so it is generally better to have a test certificate.
After the faucet is ground and polished, the surface should be plated with nickel or chrome to prevent oxidation of the faucet. After nickel or chrome plating, the faucet should be tested with neutral hydrochloric acid. After the test, the coating should be free of rust within a certain period of time. When consumers buy, it is best to place the faucet in a well-lit place for viewing. The surface of the faucet should be as bright as a mirror, without any oxidation spots, burn marks, no pores, no bubbles, no leakage plating, and uniform color; There is no burr or sand when you touch it by hand; after pressing the faucet with your finger, the fingerprint will spread out quickly, and it is not easy to attach dirt.
