The stars are made of aluminum alloy 7075T651 (and not the analogue B95T1). It is from 7075T651 that the lightest and at the same time wear-resistant sprockets are produced by the world's best manufacturers. Processing is carried out on a high-precision 3-axis CNC machine.
This allows you to achieve high accuracy of the tooth profile, which in turn affects its resource. Also, to increase the resource, the stars have cuts between the teeth - the so-called mud scrapers.
