Welcome, TDyoh3908!

Did you check the literature on Internet? First Google page:
http://www.cleanroom.byu.edu/wet_etch.phtml
https://engineering.dartmouth.edu/microeng/processing/etching/Miscellaneous%20Etchants.pdf
http://vector.umd.edu/images/links/Handbook_of_Metal_Etchants.pdf

The final choice uses to depend on more constraints than the material to be etched. Like: not destroy the patterning mask nor the underlying materials, keep the wafers clean, and so on.
