U.S. Materials Atlas
Who actually makes it, who stocks it, and who can do it to your material. A sourcing reference for the American industrial base, built around the two questions a buyer actually has: I need to buy a thing, and I need someone to do a thing to my thing.
Metals
Bought as mill product and worked by deformation, casting and machining.
Composites
Bought as fiber, fabric, prepreg and core, and processed by layup, cure and infiltration.
Technical Ceramics
Harder than any metal and lighter than most, but brittle rather than ductile. Bought as powder, pressed and sintered to shape, then finished with diamond abrasive because nothing else cuts them.
High-Performance Polymers
Metal replacement where weight, friction or electrical isolation governs. Bought as resin to mould or as semi-finished stock shape to machine.
How this is organized
Products
Things you buy by the pound or the piece. Plate, bar and forgings in metals, prepreg, fabric and honeycomb core in composites. Every product page separates the companies that make it from the companies that stock it, because mill direct and distributor are different purchases with different lead times, minimums and traceability.
Services
Things done to material you already own. Hot isostatic pressing and vacuum heat treatment in metals, autoclave cure and fiber placement in composites. Each page lists the suppliers who perform it, with the certification and capacity notes that decide whether they can take the job at all.
