Alloy wheels
In my previous post, we talked about steel wheels. Now it's time for alloy wheels. This type of wheel attracts many people with its very elegant design. Along with its design, its real strength is that it's very efficient, lighter than steel, and does its job very well. An alloy is a mixture of metal and other elements. The presence of elements such as aluminum and magnesium in its composition and the fact that almost no iron is used makes it lighter, and note that it cools faster than steel. Quick cooling is a very important function for performance.
During the 1960s, alloys made of magnesium were popular, but they were very brittle and due to their lack of ductility, they were easily damaged and cracked, and magnesium is a highly corrosive material.
After that, only aluminum alloy wheels took the place of magnesium and became widespread in motorsport competitions. Aluminum alloy itself was one of the preferred materials even in the 1920s, but its worldwide adaptation came after the 60s.
In 1924, the Bugatti type 35 car was the first in history to test aluminum alloy wheels.
