Chemical Film vs. Anodize

It’s been a while since we’ve posted, so we figured we would give you a post relative to what we have seen recently in manufacturing. For some reason, we have been seeing a lot of engineers who are calling out the incorrect finish for their parts, and we want to help set the issue straight! Simply put, chemical film (also known as┬áchromate conversion, yellow iridite, or alodine) and anodize are NOT the same thing. Most people assume that they may have similarities, that they can be used interchangeably, but this is not the case for most instances.
