A more cost-efficient brazing filler metal - more than the nickel-based brazing alloys commonly used - was launched by Hoganas AB (www.hoganas.com).

Developed in close cooperaton with customers to ensure that it met their needs for brazing properties and finished component characteristics, BrazeLet F300 is geared towards high-temperature brazing of stainless steel applications, used in extreme environments. It also provides a number of property-related benefits: excellent flow properties, corrosion-resistance, and a joint strength comparable to the best nickel-based brazing alloys.

“Due the unique patent-pending iron-chromium alloy, we have succeeded in creating a brazing filler metal that utilizes iron's positive effects, while also retaining the important corrosion resistance and strength properties that are found in nickel-based brazing alloys,” said manager of the brazing market segment at Hoganas AB, Rose-Marie Yttergren.

“We see considerable potential in several sectors, such as heat exchangers for the automotive industry and in industrial applications,” Yttergren continued. “Exhaust emission control systems for diesel engines is also an interesting market for us, not least because requirements for emission control are being continuously tightened up, most recently with EU directive Euro 5 and in the USA, US 07.”
