Both solutions are used in the Aluminium etch bath shown to the right. I must be written on which one is in. | Both solutions are used in the Aluminium etch bath shown to the right. I must be written on which one is in. Solution no. 1 is the most used solution for etchning oure aluminium. Solution no. 2 is primarily for etching aluminium mixed with a small percentage of silicon. | ||
