Introduction to Self-Fluxing Alloy Powder
Self-fluxing alloy powders are a specialized category of metal powders designed for thermal spray applications, particularly in environments requiring high wear and corrosion resistance. These powders typically consist of a base of nickel or cobalt alloyed with elements such as chromium, boron, silicon, and iron. The unique property of self-fluxing powders is their ability to melt and flow during spraying, forming dense, metallurgically bonded coatings without the need for external flux.
In the B2B industrial sector, self-fluxing alloy powders are widely used for hardfacing, surface engineering, and component repair across multiple verticals such as:
- Oil & Gas
- Aerospace
- Power Generation
- Mining
- Automotive Manufacturing
- Marine Engineering
With the rise of additive manufacturing and thermal spray technologies, the demand for high-quality self-fluxing powders continues to surge. Industrial buyers, OEMs, and contract manufacturers are increasingly seeking reliable suppliers capable of delivering consistent, high-performance powders in bulk.
Shanghai Truer Technology Co., Ltd. is one such trusted metal powder manufacturer and solution provider, offering advanced additive manufacturing materials, including a range of self-fluxing alloy powders tailored for critical applications.
