5086-H116 4" x 6" Test Panel
5086-H116 aluminum (AMS 4056) 4" x 6" test panels are available in a wide range of gauge thicknesses and surface finishes.
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.
Premium panels are cut to size, deburred, and then carefully inspected to ensure that at least one as-rolled side has zero detectable surface scratches or oxidation. Metaspec's standard is that if a visible scratch can be detected with a fingernail, then that side of the panel is not premium grade. The reverse side of the panel may have some detectable scratches – premium 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 also scrubbed with soft material to remove visible surface oxidation. 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 panels, but this high level of surface condition is not necessary for some applications.
Premium panels may also be polished or sanded on one or both sides, offering an even higher level of surface finish quality. Other services, including holes, stamping, or serializing, are available on request.
