Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation). A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings[ and the Statue of Liberty. Copper tarnishes when exposed to some sulfur compounds, with which it reacts to form various copper sulfides.
UNS C12000 is a copper alloy that is composed of copper, iron, and manganese. This alloy has excellent mechanical properties and is used in a variety of applications due to its corrosion resistance, heat resistance, and machinability. It’s also relatively easy to weld, making it a versatile material for many industries. Let’s take a closer look at the composition, properties, uses, corrosion resistance, heat resistance, heat treatment, and machining of Copper C120.
