Alloy

In the context of bicycles, “alloy” generally refers to aluminum alloys, which are mixtures of aluminum with other metals like magnesium, silicon, or zinc. These alloys are used in bicycle frames and components because they offer a good balance of strength, lightness, and affordability compared to pure aluminum or other metals. While other metals like titanium and steel can also be alloyed, “alloy” on a bike usually means aluminum alloy.
