Cobalt-Based Alloys Precision Balls Description

Material selection

Our company's finished balls are made of high-quality cobalt-chromium-tungsten alloy materials, cast by high-precision molds, and mirror-polished. We strictly control the proportion of ingredients, size, minimum tolerance, surface finish, and other standard requirements, and will conduct quality control and performance testing before delivery.

Features

Cobalt-Based Alloys Balls have a series of excellent properties such as high hardness, high compressive strength, good toughness, fatigue resistance, corrosion resistance, wear resistance, high dimensional accuracy, high-temperature resistance, low thermal expansion coefficient, good biocompatibility, and long service life.

Application

Cobalt-Based Alloys Precision Balls are mainly used as wear-resistant parts for valves, pumps, bearings, and various industrial equipment. They can be widely used in aerospace, petroleum processing, marine engineering, industrial machinery, medical equipment, electronic devices, scientific research, jewelry decoration, and other fields.

Grade

Stellite 6 - High carbon, high chromium, high tungsten, with good wear resistance and mechanical properties, often used to make cutting tools, nozzles, and valves.

Stellite 12 - High chromium content, excellent corrosion resistance, suitable for food processing equipment or marine engineering applications.

Stellite 20 - Combines excellent wear resistance and corrosion resistance, especially suitable for valves, pump bodies, and other components that need to resist corrosive media.

We can provide customized services on different grades and sizes.
