aluminum coated hafnium, but rather Al2Hf on the surface. Formation of intermetallic materials by using ball mills is common (mechanical alloying, MA).8 The high-energy impacts of the milling balls break-up the starting powders and generates the intermetallic species as intermediates during the production of amorphous alloys.

Ball End Mills | McMaster-Carr
Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

Aluminum powder (Arno Hahma; Gerald L. Hurst; Tom Perigrin)
Milled aluminum is made by performing the same process in a ball mill. The action is less compressive. It is said that stamped aluminum is denser, and gives a different reaction than the milled. ¥ Flake aluminum can also be made by the expensive process of gluing aluminum foil to sheets of paper and hammering it flatter and flatter.

That's why charcoal is typically added during the ball milling process. It is likely that if very finely powdered aluminum wasn't covered in charcoal, that it could prove to be pyrophoric.

SOP: Reactive Chemicals | PennEHRS
A self-heating substance is a solid or liquid substance, other than a pyrophoric substance, which, by reaction with air and without energy supply, is liable to self-heat; this substance differs from a pyrophoric substance in that it will ignite only when in large amounts (kilograms) and after long periods of time (hours or days).
