Aluminum alloy wheels have gradually become popular, becoming the first choice for more people. Is the aluminum alloy wheel forging or casting?

In fact, aluminum alloy wheels are forged and cast, but the aluminum alloy wheels with different manufacturing methods are different in many ways. Forging wheels have high production costs, high prices, and relatively good quality. Forging wheels are made of steel molds, softened aluminum blocks, and stamped. The structure of the internal molecules is constantly changing, and the pressure is more under pressure under high temperature. The manufacturing process of forging wheels is complex and fine, and the design is better.

On the other hand, the cast aluminum alloy wheels formed by casting aluminum liquids in sand -shaped can be produced in large quantities after cooling. Compared with the precision forging wheels, the manufacturing process will be more rough, which makes the cost lower and the price is lower. However, some heavy cars will first choose forging wheels. After all, quality is king, and travel safety is the most important.

Alloy wheel

In the automotive industry, alloy wheels are wheels made of aluminum or magnesium and its alloy. Alloy is a mixture of metal and other elements. They usually have higher strength than pure metals, while pure metals are usually softer and more ductile. Aluminum or magnesium alloys are usually lighter at the same intensity, providing better thermal conductivity, and usually have a better appearance than steel wheels. Although steel is the most commonly used material in wheels and is an iron and carbon alloy, the term “alloy wheel” is usually used to make a non -ferrous alloy wheels made of the following materials.

The earliest light alloy wheels were made of magnesium alloy. Although it is not popular among ordinary transportation, it is still popular throughout the 1960s, although the number is very limited. In the mid-to-late 1960s, aluminum castings were improved, making the wheels less crispy and safer. Prior to this, most aluminum wheels were low, and the extension rate was usually between 2-3%. Because the light-alloy wheels were usually made of magnesium at that time, these early wheels faulty was later blamed for low ductility of magnesium alloy, and in many cases, these wheels were aluminum wheels with poor casting quality. Once these improvements of aluminum castings are widely used, the aluminum wheels replace magnesium alloys and become low-cost and high-performance racing wheels.
