Copper Slag Sand Blasting: Pros And Cons
The process involves combining copper slag with air and applying it with very high force to the surface. The force with which the copper slag is released onto the surface easily removes dirt, rust, paint, and coatings. Due to the violent impact, a surface profile is created that can be used as a new adhesion layer.
