Dear friends
I have tried to electroetch 1050 aluminum alloy by 5ml phosphoric acid + 95ml H2o under 1 to 10 volts. However, it was a complete failure even after etching for 6 min.

Please help me if you know how to overcome this problem.

Thank you very much
Best regards

What does failure mean?
All you wish to do is electroetching aluminum?
Why not NaOH http://www.youtube.com/watch?v=E5QXOynT-Fs
Is the oxide layer thin? I usually get at least electrolysis and some etching with tap water. Are any bubbles coming out?
Are you sure you used the right polarity?

A few startup questions.
