The copper clad aluminum button is one of the metal buttons. In many clothes, copper clad aluminum buttons have been widely used.
First, the characteristics and quality indicators of copper clad aluminum buttons
Copper Clad Aluminum Buttons Due to the use of H62 brass as the surface material, its color is similar to the color of 18K gold, so it has a strong decorative, and after an excellent surface treatment method, it can ensure long-term use without discoloration rust. In addition, the copper surface of the copper-clad aluminum buttons is very thin, with very little copper. At the same time, the copper-clad aluminum buttons are made of aluminum alloy, which ensures the mechanical strength of the buttons. The absolute strength of the buckle handle can reach more than 300N, so that the copper clad aluminum button can be used under any condition without falling off the button phenomenon.
Second, anti-corrosion treatment of copper clad aluminum buttons
The basic method of anti-corrosion of copper is to use bright acid polishing to make the surface of H62 brass display its brightness close to 18K gold. The protective film is then immersed or sprayed on the surface with a repeated coating method. The bottom layer of the impregnated paint is a paint type with good sealing performance to improve its protective performance; the sprayed part requires the use of a paint with high hardness in order to improve the abrasion resistance of the paint film and prolong its use time, thereby ensuring the long-term use of the buttons. Will not change color and rust.
