Device
Composers, as they are called, are assembled from two or three parts. The bolts of steel or titanium are used to attach them. Because titanium is free from corrosion, bolts of this metal are preferable. The drive can be divided into such elements as the rim and the drive itself. Different methods of producing composite disks are used. Thus, the rim is rivated, and the method of hot casting is used to make the disc. The bulk of a composite disk, in turn, can be whole or split.
Varieties
The composite disks include the so-called spinner-drive disks. Such discs consist of a carrier and a decorative part. They are bound by a bearings that allows the disc to spin both on motion and its decorative part when it stops. It's about inertia, because of the edges of the decorative disk, and it's a little bit of iron.
First of all, the composite structure is needed to reduce the weight of the disk. Here's an example: the composite disk r18 weighs approximately five kilograms, and the regular disk is twice as much.
Another impersonal virtue of such discs is their repairability. The removable rim, if damaged, can be replaced with a new one without purchasing the disk itself. However, the bulk disks are less prone to wear.
