Will ferric chloride etch aluminum?
Score: 4.4/5 (74 votes) Do NOT use ferric chloride on aluminum. Metal as thin as 24-gauge can be etched – just leave it in for less time than you would for thicker metal. If you want to etch both sides or etch really deeply, use 20-gauge metal or thicker.Does ferric chloride etch Aluminium?Acid etch...
