How about the preservation performance of copper profiles

Copper, one of the earliest metals discovered in human history, is somewhat hard, extremely tough, resistant to wear and has good ductility, as well as good heat and electrical conductivity. Therefore, the copper profile produced after copper processing is good and easy to process. Compared to iron and aluminum, copper profiles are relatively rare elements, and copper profiles have good preservation properties.

Copper profiles have many valuable physical and chemical properties. The main point is that its electrical conductivity is much higher than other base metals and iron, only silver exceeds it. Similarly, its thermal conductivity is much higher than other metals except silver. Copper profiles are generally highly resistant to corrosion, as evidenced by their use in architecture and sculpture over thousands of years.

When copper profiles are exposed to air for a period of time, they undergo oxidation. The surface can form light green copper film once the film is formed, will have powerful protective effect to the internal metal, copper profile has the characteristic of resisting organic acid and alkali (except ammonia water), because this can be buried underground or immersed in water and not corroded.

From the above, the advantages of copper profile as a home decoration profile is very prominent, although the light green copper film formed after oxidation in the air has a strong protective effect, but because of its beauty is unbearable, so in the usual copper profile maintenance needs to work a little.
