ASTM D2649 Anodized Aluminum Test Panels

Aluminum test panels used in ASTM D2649 (Corrosion Characteristics of Solid Film Lubricants). The test panels are made of 2024 aluminum and measure 3" x 6" x 0.020". The test panels are anodized in accordance with ASTM D1730 Type C Method 2 before testing. Two panels (one coated with the test film lubricant) are assembled at a 90° angle inside an aluminum channel and are fixed in place for the duration of the test. Two more panels (both uncoated) are also assembled and included in the test as a check on the test panel condition.

Metaspec provides these test panels with an as rolled surface finish or with the ASTM D1730 coating (inquire for availability). Customized test panels are available on request.

Regular test panels are PVC-coated on both sides, cut to size, deburred, and packed in bundles. These panels may have some minor surface defects and will have mill oil on the surface, as these are the sheets in “as-received” condition from the aluminum mill.
Pre-cleaned panels are cut to size, deburred, and wiped and cleaned on both sides with solvent per ASTM D609 to remove mill oil and fingerprints. The panels are also scrubbed with soft material to remove visible surface oxidation. Pre-cleaned panels have an as-rolled surface finish, which may have minor scratches or surface defects. The panels are interleaved in plastic to protect the surface. These panels are not PVC coated when shipped, making the panels ready to use for most applications.
Premium polished panels are cut to size, deburred, and polished with a very fine sanding belt to remove any visible defects on one side. The reverse side of the panel may have some detectable scratches – premium polished panels are only premium on one side, not both. The panels are wiped and cleaned on both sides with solvent per ASTM D609 to remove mill oil and fingerprints. The panels are interleaved in plastic to protect the surface. These panels are not PVC coated when shipped, making the panels ready to use. Most Metaspec customers prefer our premium polished panels, but this high level of surface condition is not necessary for some applications.
