What is mil-a-8625?
Military specification MIL-A-8625 is the model spec for many components that need anodized for the military and/or aerospace industry. The specification covers all the requirements needed for six types and two classes of electrolytically formed anodic coatings on aluminum and aluminum alloys.
Is anodized aluminum RoHS compliant?
While a metal itself does not contain hexavalent chrome, there are anodizing processes and conversion coating processes available that leave it hexavalent-free and RoHS compliant.
Is chromic acid anodizing RoHS compliant?
The following treatments are not RoHS compliant or may not be RoHS compliant: Dichromate sealed sulphuric anodising. Chromic anodising.
What RoHS means?
Restriction of Certain Hazardous Substances
What is RoHS? RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment. This restriction is anchored in EU Directive 2011/65 / EU.
Is trivalent chromate RoHS compliant?
The Trivalent Chromium Process (TCP) provides a non hexavalent chromate conversion coating compliant with RoHS, ELV and WEEE directives. It compares favorably with the hexavalent coatings providing a conversion coating that fulfills the corrosion, paint and electrical requirements of the different specifications.
Is yellow zinc RoHS compliant?
Only trivalent yellow zinc plating is compliant to the Restriction of Hazardous Substances (RoHS) directive, which bans the use of certain substances such as the carcinogenic*, hexavalent chromium (used in the hexavalent yellow plating process), due to health and environmental concerns.
What is the Mil-a-8625f anodic coating specification?
MIL-A-8625F, MILITARY SPECIFICATION: ANODIC COATINGS FOR ALUMINUM AND ALUMINUM ALLOYS (10 SEP 1993)., This specification covers the requirements for six types and two classes of electrolytically formed anodic coatings on aluminum and aluminum alloys for non-architectural applications (see 6.1).
What is the Mil-a-8625f Amendment?
MILITARY SPECIFICATION ANODIC COATINGS FOR ALUMINUM AND ALUMINUM ALLOYS This amendment forms a part of MIL-A-8625F, dated 10 September 1993, and is approved for use by all Departments and Agencies of the Department of Defense.
Are alloy aluminum ANSI 6061-T6 or 5052-H32 RoHS compliant?
Are Alloy aluminum ANSI 6061-T6 or 5052-H32 RoHS compliant? A. As far as I can tell via the directive the material, as is, is RoHS compliant. If it has a chem. film containing Hex chrome it would not comply.
What is the difference between ROHs and reach?
Other standards like REACH may effect what chemicals you can use in a process within the European Union, but RoHS is primarily about recycling and is concerned with what is actually in/on the parts you ship into Europe. Assuming reasonable rinsing, a deoxidizer used before anodizing should be non-detectable in the finished product. A. Hi all.
