It should be noted that it is effective on most metals such as <strong>steel<\/strong>, <strong>aluminum<\/strong>, <strong>copper<\/strong> or <strong>silver<\/strong>.

Surface irregularities are thus evenly dissolved.   <\/p>\n\n<p style=\"font-style:normal;font-weight:400\">This method achieves unequalled levels of finish, with roughness below <strong>0.01 micrometers<\/strong>. <strong>Precision <\/strong>and <strong>automation <\/strong>make it the process of choice for <strong>highly technical parts<\/strong>.<\/p>\n\n<p style=\"font-style:normal;font-weight:400\">Alternatively, <strong>chemical polishing<\/strong> involves controlled chemical reactions.
