Powder metallurgy is a metal forming process in which compacted metal powders are heated to just below their melting point. Although the process has been around for more than 100 years, over the past quarter-century it has been widely recognized as a superior method for making high-quality parts for a variety of important applications.

The hammering process welded and elongated the iron crystals. As in the blast furnace, slag acted as a flux to reduce oxidization while the iron was welded together. By working from the center outward, excess slag was squeezed to the ends of the bars. The result was the main product of the iron works, wrought iron merchant bars.
