What Are The Differences Between Copper And Brass?

By definition, brass is an alloy of copper and zinc. If it is composed of only these two elements, it is ordinary brass, but if it is composed of these two and other elements, it is special brass. Copper is a relatively pure copper, because the color of copper appears purplish red, so copper is also called red copper.

The difference in appearance color: we observe copper and brass will find that the color of brass is generally golden and shiny, but the color of copper is rose red and shiny, so we can also distinguish from their appearance color

The difference in composition: the composition of copper is mainly copper, and the content of copper can be as high as 99.9%, but the composition of brass has copper and zinc, relatively special brass may also have other magazines, so we can also be very good to distinguish from the composition.

Strength difference: the strength of copper and brass is different, we can distinguish from the strength, the composition of brass is more so the strength of brass is generally relatively high, but the composition of copper is mainly copper, basically no other impurities, so the strength of copper is relatively low.

The difference in density: the density of brass is 8.52-8.62, the density of copper is 8.9-8.95, so the density of copper and brass is relatively large, the density of brass is small.

Conductivity difference: due to contain copper in the copper and brass components, so the copper and brass can conduct electricity, but copper and brass components and difference, so the conductivity of the copper and brass is different, the composition of brass is more so some relatively low conductivity, the composition of copper is copper, so the conductivity is higher.

The difference between corrosion resistance and cutting performance: the corrosion resistance of brass is slightly worse, but the cutting performance is better than the price, the corrosion resistance of copper is better, but the cutting performance is poor.

The difference in price: the price of red copper is more expensive than that of brass.
