1. Cost is less. 2. Light weight when compared to COPPER BB. 3. Lot of free electrons. 4. Safety: no theft occur.

thanks Imayavaramban about the answer, but aside from these advantages there are some disadvantages for sure and needs more complicated technology to produce it compared with the pure busbars, e.g. in the switchgear boxes when copper clad aluminum (CCA) is replaced instead of Cu the size of the boxes and the location should be extended and it might be costly. do you think the cost would be less? thanks again

Not significantly
