Mill Finish Aluminum, the Natural Appearance of Aluminum

AJ Oster stocks a complete inventory of mill finish aluminum sheet and coil. Mill finish aluminum is the natural appearance of aluminum as it comes from the rolling mill. We primarily stock mill finish aluminum in common alloys, but can source any aluminum alloy with our extensive mill connections.

A.J. Oster offers aluminum sheet and foil gauges in a wide variety of alloys, tempers and finishes. These products can be supplied in both coils and cut lengths. We also supply brazing alloys and clad metals.

AJ Oster’s mill finish aluminum products are designed to capitalize on the metal’s many unique characteristics, including low density and light weight, high reflectivity, good conductivity, UV and solar light resistance, weather resistance, high elasticity and exceptional strength.
