BrazeLet® F300

BrazeLet® F300 is a unique stainless iron-chromium-based brazing filler metal for applications operating in extreme environments. Its unique chemical composition delivers similar corrosion resistance and joint strength properties to high-performing nickel-based filler metals. However, it is a more cost-effective alternative thanks to the use of less costly metals.

BrazeLet F300 has excellent wetting properties, low brazing temperature and creates a uniform joint with high strength and high corrosion- and oxidation resistance, making it suitable for heat exchanger applications in industry and the automotive sector.

The first choice for the increasing demand of copper-free brazing, e.g. for drinking water applications and oil coolers.
