Etchants for Aluminum

Highly acidic etchants are used for oxide removal and etching aluminum in preparation for plating and metal finishing processes.  Therefore, etchants for aluminum are crucial to aluminum plating and finishing applications.

Our solutions are available in the following packaging sizes:

  • 5-gallon pails
  • 55-gallon drums
  • 300-gallon totes
