Compared with silver mirrors, copper-free mirrors are of a higher grade. After the Silver Mirror is plated with silver, a layer of copper will be plated to protect it to prevent the mirror from being damaged and easily scratched. The copper-free mirror is to replace the copper protective film with a passivation protective film, making the mirror more environmentally friendly and durable. The passivation protective film of the copper-free mirror makes the mirror more wear-resistant, and is superior to ordinary silver mirrors in adhesion and corrosion resistance.
In addition, we also sell Silver Mirror glass, silver mirror commonly known as waterproof mirror, mercury mirror, silver-plated mirror on glass surface, glass mirror, mirror glass, etc. Silver mirrors are widely used in furniture, handicrafts, decoration, bathroom mirrors, cosmetic mirrors, optical mirrors, and car rearview mirrors.
