Cobalt Powder

Cobalt Powder Description

Cobalt powder is a key ingredient in superhard alloy. Its three forms are reduced, electrolytic, and atomized. It determines the bonding property, strength, and toughness of superhard alloy.

Cobalt-based alloy powder is hard alloy powder that resists wear, corrosion, and oxidation at high temperatures. Cobalt is the main ingredient, it also contains chromium and tungsten, and a small amount of nickel, molybdenum, silicon, carbon, niobium and tantalum making up the remainder.

These cobalt alloy powders are used in welding processes that create overlays and also in spray welding processes. These techniques can also be used to create casting and powder metallurgy components, such as high-temperature pressure valves, sawtooth and helical rotor.

Our customers are mostly alloy fabrication and coating companies from all over the world. They ordered a large quantity of cobalt powder from us. AEM is a supplier of high-density powders with customized sizes. If you didn't find the size you need, please email us. If you have any questions about powders, please contact us. We'll be happy to help you out.

Cobalt metal powder is designed and manufactured for use in high-quality cemented carbide and related products. The hard metal industry demands Cobalt spherical powder that meets high purity, fine particle size, and consistent particle size distribution standards.

Cobalt atomized powder is used to make Diamond Tools. Some of the most common Diamond Tools that are made with Cobalt include Diamond Segments, Tool Wires, Tool Blades, and more. These tools are used for cutting stones like Marble and Granite.

Spherical Cobalt Based Alloy Powder is a high-strength, high-temperature resistant alloy powder. It is mainly used in the 3D Printing industry, as well as in other high-temperature and wear-resistant applications. The main components of the alloy are cobalt, nickel, and chromium.

The addition of these elements makes the alloy more resistant to corrosion and wear. In addition, the spherical shape of the powder helps to reduce friction and improve the flow of liquids and gases. As a result, Spherical Cobalt Based Alloy Powder is an essential material for many industries.

Chemical Composition of Cobalt-based Alloy Powder

Cobalt-based alloys usually have tungsten and carbon in them. The carbon makes the alloy harder. This happens because the carbon doesn't dissolve in the cobalt very well.

All of these hard parts make the alloy stronger at temperatures that are less than 800 degrees Celsius. The Cobalt-Chromium-Tungsten-Carbide alloys usually have excellent properties like being resistant to high temperatures, oxidation, and thermal fatigue.

When the temperature of Cobalt is below 417 degrees Celsius, it has a hexagonal-closed-packed (HCP) crystal structure which makes it wear resistant. However, when the temperature rises above 417 degrees Celsius, Cobalt transforms from HCP to FCC (face-centered-cubic) crystal structure.This can cause thermal stress and can lead to cracking in the coating or overlay if not preheated to 500-600 degrees Celsius.
