Form:

This specification establishes the procedures used to produce a hard anodic coating on magnesium alloys and the properties of the coating.

Application:

This coating has been used typically to provide corrosion resistance and abrasion resistance to sand-cast magnesium alloys, but usage is not limited to such applications.

Classification:

Anodic finishes are classified by coating thickness as follows:

Class 1 Thin Coating: Coating thickness shall be in the range of 0.0002 to 0.0004 inch (5 to 10 µm) and produce a dimensional buildup on the part of 0.0001 to 0.0002 inch (2.5 to 5 µm).

Class 2 Thick Coating: Coating thickness shall be in the range of 0.0008 to 0.0010 inch (20 to 25 µm) and produce a dimensional buildup on the part of 0.0004 to 0.0005 inch (10 to 12.7 µm).

If a class is not specified, Class 1 shall be supplied.

Safety-Hazardous Materials:

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
