In the current widespread use of copper plate there are two main: copper and brass plate. These two copper plate in fact, in addition to the surface color is different, in fact, in the composition, function and usefulness are not the same, let’s take a look at what are not the same.
Purple copper copper content in 99.9%, the rest is a number of trace alloying elements, while brass belongs to the copper-zinc alloy, in which the copper content of only 60% or so, but also contains other alloys, because of this composition, so it also determines the price of purple copper plate is a little higher than the price of brass plate.
Copper plate has a high conductivity, bright surface, and brass plate because of copper-zinc alloy, so it is lower than the conductivity of copper, but has good corrosion resistance!
Copper plate because of his good conductivity will generally be used for conductive, thermally conductive device manufacturing, brass because of its corrosion resistance is generally used in high-grade decoration industry, can also be used for electronics, electrical appliances this piece.
