Car Rims Buford GA

The term, car rim refers to the wheels of an automobile. The standard wheels found on most automobiles are basic steel wheels, and many car owners opt to purchase upgraded wheels from the manufacturer or from aftermarket suppliers. Custom car rims are often made of aluminum and magnesium alloys, and are available in a wide range of styles and sizes for most automobiles.

There is a good variety of ways of constructing wheels. Most alloy wheels are made in one, two or three-piece construction types. One piece is just what it says, a wheel made in a mold as a single piece. Two piece wheels are made of two separate pieces (center and barrel) that are usually welded or bolted together. Three-piece wheels are made of three separate pieces. They have a center, and inside rim half, and an outside rim half. They are bolted together using the highest quality fasteners.

Manufacturing method is very important in the overall quality and performance of a wheel. Here are the most common types of manufacturing techniques employed:

Forging

Considered to be the best manufacturing technique, forging allows for the compression of an aluminum billet (one solid piece of aluminum) into an aluminum wheel using over 13 million pounds of pressure combined with heat. This produces a wheel that is both stronger and lighter then your standard aluminum wheel.

A subset of forging is called roll forging. In this process, a metal blank is run through rollers with impressions sunk in to their surface giving the wheel its final shape. This allows the wheel to be produced with less aluminum, reducing weight but maintaining strength.

Low Pressure Casting

This is the most common form of rim manufacturing. Much like a casting, liquid metal is poured into a mold and allowed to harden until the finished wheel is cool enough to be taken out of the casting.

Counter Pressure Casting

Opposite to low pressure casting, the liquid metal is not poured, rather it is sucked into the mold using a vacuum. This reduces impurities making the wheel much stronger than a low-pressure cast rim.

The main differences between alloy and steel rims lie in their durability and strength. Most high-performance wheels are made of an alloy and composed of aluminum, and other metallic substances. By using alloy wheels, you not only improve the looks of your vehicle but also the performance. The extra strength provides longevity as well as effecting tire wear in a positive manner.

The weight reduction will improve steering response and handling, as well as help improve acceleration and braking.
