Aluminum's light weight, superior heat dissipation, and seemingly endless design variations make it the material of choice for most buyers. Aluminum wheels can be manufactured in many ways, and each method offers advantages.

• One-piece cast wheels

  Pouring molten aluminum into a mold creates a cast wheel. The metal then takes the mold's shape as it cools and hardens. There are three types of casting methods: low pressure/gravity, counter pressure, and high counter pressure molding (HCM). Each method has its place in today's market. A wheel manufacturer will select a particular method according to the weight, strength, and finish that they have specified for that design. Naturally, the more sophisticated and costly methods produce lighter and stronger wheels but at a higher price.

   

• Forged / Billet wheels

  The two words "forged" and "billet" have become synonymous. However, the manufacturing process is called forging, while the material used is a billet. Billet is the term used for a solid piece of dense aluminum. The forge, a huge machine that exerts thousands of pounds of pressure on the metal, basically presses or rolls the billet into its fundamental form. This forging is then machined to a final finish. This process allows wheels to be built with much less material. This results in lighter weight and unique designs, because the process creates a much stronger wheel than other methods.

   

• Multi-piece wheels

  The processes mentioned above can be combined to produce a wheel of a particular strength and weight at a particular price. For example, some wheels have a cast aluminum center, welded to a steel outer, or barrel. Another type of two-piece construction features a billet center welded to a rolled outer (extruded aluminum rolled into a hoop). Still other wheels feature a split outer so that widths and offsets can be made to custom specifications. This last method is the three-piece type construction. In this type of wheel, the center can be cast, billet or forged, and is usually attached to the outer assembly by special screws or rivets.
