Copper alloy acrylic will fade in water. The fading of copper alloy acrylic depends on the maintenance method. Proper maintenance can ensure that the color will not fade for at least 3 years. The discoloration of copper alloy is mainly due to the natural oxidation of electroplating layer, which will also appear when exposed to air during wearing. Therefore, in the process of daily maintenance, we must avoid bumping and touching chemical products.
