Is chromate conversion coating thick?
No. The coating is extremely thin—typically 0.00001″ to 0.00004″—and has negligible impact on part dimensions.
What’s the difference between clear and yellow coatings?
Yellow (hexavalent) offers stronger corrosion resistance. Clear (trivalent) is RoHS compliant and better for environmental regulations.
Does it affect conductivity?
No. In fact, it preserves aluminum’s natural conductivity, making it ideal for EMI and RFI shielding.
Can it serve as the final finish?
Yes. It can be used as a standalone finish in non-cosmetic or electrically sensitive applications.
Is chromate conversion coating RoHS compliant?
Only trivalent (Type II) coatings meet RoHS standards. We offer both Type I (hexavalent) and Type II options based on your specifications.
