Properly caring for copper and bronze will truly bring out the beauty in all your projects. Not only that, but these maintenance tips will also ensure that your creations will last for many years to come.
How Resistant Are They?
Many craftsmen and contractors work with copper and its alloys because of their known resistant properties. They are suited for freshwater and marine applications, as they can fight corrosion well, and won’t exhibit rust. Even for outdoor installations like statues, gates, window frames, and the like, these metals can withstand weather exposure as well as weak acids and sulfur-containing compounds.
Effects of Certain Compounds
Stress corrosion cracking (SCC) may occur on the surface of bronze and copper when they are exposed to compounds containing ammonia. In some cases, chlorine, like those found in bleach and strong acids can also damage the surface of the metal. Generally, if the alloy has a high zinc content, it is more susceptible to SCC, and this degradation may eventually lead to the weakening of the metal.
How to Keep Them Clean
Metal craft experts say that proper care for copper, brass, or bronze sheets can be simple and hassle-free. After working with these metals, a lacquer or oil-based coat may be applied to protect the surface and create a beautiful finish. Cleaning these alloys does not need to be done frequently, perhaps once every few months. Avoid using strong polishing solutions that contain ammonia, and always consult with your metal supplier to know about the correct brands for a particular alloy you are using.
