The raw material for this product is brass. One interesting fact about copper is that its "rust," unlike iron, is green. This green patina is known as "copper green," which is essentially copper oxide formed through a chemical reaction between copper and oxygen. To prevent such oxidation, a layer of chrome is applied to the surface. Chrome is highly stable, durable, and resistant to wear. It also offers an attractive, shiny appearance, which is why car door handles often have a chrome finish. A chrome-plated copper towel rail remains unblemished because it doesn't come into direct contact with air. However, customers occasionally report rust-like spots appearing in their homes. Here’s why this might happen: Firstly, if the chrome coating isn’t properly protected, it can become damaged over time, exposing the underlying brass to air. In a humid environment, this can lead to the formation of copper oxide, resembling rust. Secondly, failing to clean the surface regularly can result in the accumulation of grime and residues. Over time, these deposits can cause dark spots to appear, giving the impression of rust. Thirdly, poor-quality water containing high levels of metal ions can contribute to the problem. If left unwiped, these metal ions can interact with moisture and air, leading to rust-like discoloration. Additionally, areas that aren’t cleaned frequently—such as hard-to-reach corners or edges—can become breeding grounds for such issues. In summary, while chrome plating is designed to protect brass, certain factors like damage to the coating, lack of maintenance, or poor water quality can still lead to unwanted oxidation. Regular cleaning and proper care can help prevent these issues and keep your chrome-plated items looking their best. led strip lights ,custom led signs,light fixtures,landscape lighting HSONG LIGHTING CO,.
