A method for making an aluminum substrate that is subjected to repeated impaction more wear resistant. The method comprises applying at least about 0.005 inch thick coating of an amorphous composition directly to only portions of this substrate, preferably after it is shaped into a product for transporting consumable materials. The coating composition to which steel, aluminum, PTFE and/or polyethylene may be added, can be thermally sprayed to the substrate surface.

Method for making aluminum sheet and plate products more wear resistant

A container module for intermodal transportation and temporary storage of dry flowable product includes a pressure tank supported by hanger plates welded to end frames of a support frame defining a standardized container envelope. The pressure tank has a wall with a flat top center section and short flat side sections joined by upper cylindrical intermediate sections and lower cylindrical sections below the flat side sections which blend into a plurality of intersecting, downwardly discharging hoppers. Elongated beam members extending along each side of the support frame tie the hoppers together to resist bending of the suspended tank.

A single hull or doubled hull boat manufactured from stretch formed aluminum alloy. Alloys of the AA 6000 series alloys are particularly suited for forming of small to medium sized water vessels.

Boat manufactured from formable aluminum

The present invention is directed to the enabling formability of the 6000 series alloys for the manufacture of small to medium sized water vessels.

An elongated metal frame structure for connecting a large elongated container to a vehicle employed in transporting the container. The frame comprises a plurality of aluminum alloy tubes connected together at certain corners of the frame by corner assemblies. The assemblies comprise a 'standard' cast iron or steel fitting and at least one steel member connected to one face of the fitting. The exterior surfaces of each steel member are coated with materials that are effective in electrically separating the steel member from an aluminum tube of the frame when the corner assemblies and aluminum tubes are assembled together. The size of the steel members in cross section with the materials applied to the surfaces of the steel member is such that the steel member can slip into the end of the aluminum tube located at a corner of the frame.
