By Wheel Master

Forging uses intense heat and pressure to transform a [solid} slug of alloy material into the final shape of a wheel. Forged aluminum is stronger than cast aluminum, yet less material is needed to produce the same "cast alloy wheel", which results in a lighter product. Because of the basic limitations inherent in forging, most forged wheels are two or three piece units. In two-piece construction, a centre is forged and welded or bolted into a spun or stamped outer rim. In a three-piece wheel, the centre is bolted to an inner and an outer rim half. This stands as an advantage of being easily customizable for a variety of widths and offsets.
