Our company's copper clad steel uses a welding process. Welding is not the same as plating. Welding is the combination of copper strip and steel by high temperature and high pressure to achieve bimetal metallurgical bonding. We use international quality low carbon steel wire and 99.99999% high performance pure copper belt. Therefore, the welded copper clad steel has both high strength of steel and high electrical conductivity of pure copper. The outer copper strip protects the steel well and therefore has excellent corrosion resistance.
The anti-theft advantage is obvious. As we all know, copper theft is already very common. Because copper-clad steel does not have the value of recycling, thieves will not steal copper-clad steel. Therefore, the use of copper-clad steel instead of pure copper can prevent theft and property.
