While copper is not as widely used as iron or steel, it offers numerous advantages that these metals cannot match. Pure copper has exceptional electrical and thermal conductivity, making it essential in the manufacturing of electrical machines, wiring, and more.
Red copper is an extremely pure metal, typically produced through the electrolytic refining of raw copper.
Red copper is very malleable; a drop of pure copper can be stretched to 2,000 meters and can be flattened thinner than a sheet of paper, even becoming transparent, drifting in the wind.
Brass is an alloy of copper and zinc. The color of brass varies depending on the zinc content. If the zinc content is between 18% and 20%, the brass appears red; between 20% and 30%, it is brownish-yellow; between 30% and 42%, it takes on a light yellow hue; and between 50% and 60%, it shows a bright yellow color. In industrial applications, brass typically contains 45% zinc or less.
Black copper is an alloy of copper and tin, sometimes including zinc, used primarily for casting statues. While many metals contract when cold, black copper expands. Its high resistance to wear makes it ideal for manufacturing ball bearings.
Nickel-brass alloys create white copper, which is used to produce shiny, rust-resistant containers.
