На основе никеля пайки металлов

Welding joints of Nickel-based Brazing Metals are with high strength in high-temperature and excellent corrosion resistance. Nickel base brazing metals are suitable for brazing stainless steel, heat-resistant steel and other high-temperature alloy which is always working under high temperature. It has been widely used in the welding of aerospace engines, heat exchangers, thin-walled stainless steel components and complex structure parts. It also can be used for brazing drilling tools, diamond products and handicrafts. In addition, nickel-based brazing metals can also be used in brazing components of which working temperature is near liquid nitrogen Type chemical composition Melting point Brazing temperature Particle size distribution Ni Cr B Si Fe C P BNi74CrSiB 13-15 2.75-3.5 4-5 4-5 0.6-0.9 - - 975-1038 1065-1205 -200 BNi75rSiB 13-15 2.75-3.5 4-5 4-5 0.06 - - 975-1075 1075-1205 -200 BNi82CrSiB 13-15 2.75-3.5 4-5 2.5-3.5 0.06 970-1000 1010-1175 -200 BNi92SiB 2.75-3.5 4-5 0.5 0.06 980-1000 1010-1175 -200 BNi93SiB 9.5-10.5 2.2-2.8 3-4 2-3 0.06 W:11.5-12.5 970-1075 1150-1200 -200 Ni71CrSi 18.5-19.5 9.75-10.5 0.10 1080-1135 1150-1205 -200 Ni89P 10-12 877 925-1025 -200.
