Co45 Self-Fluxing Powder
Cobalt-base self-fluxing powder with wear, corrosion and heat resistance.
Material overview
The Self-Fluxing Alloy Powders catalog describes Co45 Self-Fluxing Powder as follows: Cobalt-base self-fluxing powder with wear, corrosion and heat resistance. Reviewers should evaluate HRC 45-55, retains hardness at high temperature, and excellent corrosion and thermal shock. The grade record lists High-temperature valves, engine components, hot-working tools, and pump and chemical parts among typical applications. The dataset currently includes 10 property records covering chemical composition, mechanical properties, and physical properties. Standards and form records reference GB/T 15007 and Powder. Final supply conditions remain subject to specification, inspection, and export-control review.
