Stellite® cobalt base alloys consist of complex carbides in an alloy matrix. They are resistant to wear, galling and corrosion and retain these properties at high temperatures. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.

Satin Finish: Visually speaking, a satin finish is comparatively more subtle and has less marks than a brushed finish. In terms of texture, it should actually feel smooth like a regular polish. Brushed Finish: A brushed finish is more rustic, with heavier definition on the visible strokes. When a brushed finish is touched, you should be able to feel the stroke marks.

Corrosion resistance of the currently used 316L stainless steel, cobalt-chromium, and titanium-based implant alloys relies on their passivation by a thin surface layer of oxide. Stainless steel is the least corrosion resistant, and it is used for temporary implants only. The titanium and Co-Cr alloys do not corrode in the body; ...

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Twist Drills. General Description: Twist drill bits are the most common type of drill bit and are used for everyday drilling in all types of material. They are also the most confusing due to the sheer number of size, tip, and material specifications. Length Designations: The length of a twist drill has much to do with its rigidity - a shorter bit will be stronger and less likely to wander or ...

Cobalt poisoning can occur when you are exposed to large amounts of it. There are three basic ways that cobalt can cause poisoning. You can swallow it, breathe it into your lungs, or have it come in constant contact with your skin. Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants.
