High-Performance Material for Extreme Heat and Wear

Our Cobalt-Based Alloy Powder offers excellent combined performance in high-temperature wear and thermal shock resistance. The chemical composition follows the Co-27Cr-4.5W-1.1C formulation, delivering a cladding layer hardness of 41 to 47 HRC. This powder is similar to cobalt chrome powder but differs in tungsten and carbon content, making it suitable for different wear and heat resistance conditions. It is widely used in nuclear valve sealing surfaces, aircraft engine combustors, chemical high-temperature reactors, and hot extrusion dies. Our powder is produced using gas atomization with a spherical ratio above 93%, ensuring stable powder feeding and dense cladding layer quality. Our Cobalt-Based Alloy Powder meets the highest quality standards for critical applications.

Low Oxygen Content for Reliable Performance

The particle size range of this powder is 45 to 150 micrometers. The oxygen content is controlled below 170 parts per million. The flowability does not exceed 16 seconds per 50 grams, and the apparent density ranges from 4.3 to 4.7 grams per cubic centimeter. Cobalt-based alloy powder offers excellent thermal fatigue and hot corrosion resistance at temperatures above 600 degrees Celsius. Our technicians can evaluate the suitability of this powder based on your service temperature, media, and stress conditions. If you need higher hardness or better high-temperature performance, we can also recommend other formulations in the same series. Our Cobalt-Based Alloy Powder delivers reliability in extreme environments.

Process Verification and Small-Quantity Orders

Cobalt-based alloy powder is typically used in applications requiring extremely high reliability. Before formal procurement, we can conduct process verification for you. You can send your workpieces to our factory, and our engineers will complete cladding trials according to your technical requirements. We provide complete process parameter reports. After equipment delivery, we offer remote process guidance to ensure you achieve the same cladding quality as the sample trials during mass production. We support small-quantity orders with a minimum order quantity of 1 kilogram. Order our Cobalt-Based Alloy Powder with confidence.
