A material handler formed from isotropic textured aluminum sheet rolled by rolls indented with spherical media, such as steel ball bearings, producing a sheet with a low coefficient of friction relative to particulate matter like flour. The slippery sheeting may be used to make tanks, silos, conduits and guides to facilitate storage and flow of the particulate matter.

Apparatus and method for imparting selected topographies to aluminum sheet metal and application there for

Steel tooling for die-casting low iron content aluminum alloys is surface treated with a layer of CrN applied to a thickness of at least 4 microns, and preferably 5-10 microns, by physical vapor deposition (PVD), and preferably a steered are evaporation PVD process. The CrN protects the steel tooling from dissolution and erosion by the highly active molten aluminum.

CRN coated die-casting tools for casting low aluminum iron alloys and
