Bright Dip aluminum anodizing achieves a highly electro polish finish similar to the quality of aluminum plating. In contrast to aluminum plating, Bright Dip aluminum anodizing is a chemical process that brightens aluminum and does not leave deposits on the surface of the part. The degree of brightness is dependent on the type of alloy as well as the surface finish of the part. With some aluminum cleaning chemicals and aluminum plating pre-treatment cleaners make it more possible to achieve a reflective, mirror type of finish.
