These days some alloys of aluminium are equally safe as copper and can be directly replaced with copper for electrical wiring
. Copper Clad Aluminum short-formed as CCA is composite wire which comprises of aluminium core clad with ETP copper. Although this material consists of 90% aluminium, it has electrical properties that are equivalent to copper. Many Aluminium Wire Suppliers produce broad line, round, flat, square and also rectangular aluminium wire that are copper clad. This type of electrical wiring is extensively used in many applications and has some advantages of being light weight when compared to aluminium.
