Översikt

BNi-7 powder är en nickelbaserad hårdlödningslegering som erbjuder exceptional Korrosion motstånd och oxidationsstabilitet at high temperatures. It is designed for brazing applications where korrosionsbeständighet och hög termisk stabilitet are critical. Unlike other nickel-based brazing alloys, BNi-7 has a relatively låg smältpunkt, making it easier to work with on temperature-sensitive components.

What sets BNi-7 powder apart from other alloys is its low boron and silicon content, which translates to a low melting range och minimal joint erosion during brazing. The result is a smooth, clean joint that doesn’t compromise the integrity of the base materials.

Key Properties : Summary

• Smältintervall: 970°C – 1000°C
• Sammansättning: Primarily nickel (Ni), with small amounts of phosphorus (P), chromium (Cr), and silicon (Si)
• Motståndskraft mot korrosion: High resistance to oxiderande och minska miljöerna
• Tillämpningar: Idealisk för flyg- och rymdindustrin, fordonsindustrin, kraftproduktion, medicintekniska produkter, och mer
