Metal, Powdered

Name:
Metal, Powdered
Detailed information:
Metals are produced in powdered form for a variety of uses in several industries. In this form they are the raw materials for powder metallurgy in which the powders are pressed in molds and heated (sintered) at high temperature. Metal powders range in size from −325 mesh (0.045–0.060 mm “diameter”) to +100 mesh and are available in practically all industrial metals. They are produced by machining, milling, shotting, granulation, atomizing, condensation, reduction, chemical precipitation, or electrodeposition. Their properties and purities vary with the method of preparation.

Hazard:

Dangerous fire risk, especially as dust. Toxic by inhalation.

Use:

Electric, automotive, machinery, tool and refractory-metal industries; paint pigments, flares and incendiary bombs, brazing materials, calorizing, metal-spraying, metallurgical agents; heat-generating agents, catalysts, etc.
