Nickel Filler Metals
Joining Heat Resistant Nickel-Based Alloys and Stainless Steel
Nickel-based materials are best used for the joining of stainless steel and Ni (nickel) based heat resistant alloys. Nickel-based brazing alloys are suited for brazing and heat treating combination operations.

| Hi-Temp 721 Similar to Hi-Temp 720 but of particular interest where higher carbon content is not permissible. Slower slow than Hi-Temp 720. |
1790 | 977 | 1970 | 1077 | 3.1 | 14 | 4.5 | 73.84 | 4.5 | 0.06 C |
BNi-1A | ||||
| Hi-Temp 820 Widely used low melting filler metal for furnace brazing aircraft parts, medical devices and other food handling components. Good flow generous fillets, low base metal penetration are characteristics of this filler metal. |
1780 | 971 | 1830 | 999 | 3.1 | 7 | 3 | 82.34 | 4.5 | 0.06 C |
BNi-2, AMS 4777 | ||||
| Hi-Temp 910 Flows freely and less sensitive to atmosphere dryness than the other filler metals. Better for tight/longer joints. |
1800 | 982 | 1900 | 1038 | 3.1 | 1.5 | 90.84 | 4.5 | 0.06 C |
BNi-3, AMS 4778 | |||||
| Hi-Temp 930 For stainless steels, Ni & Co base alloys with thin sections--jet engine parts and chemical equpment. More sluggish and is better for wide gap applictions. |
1800 | 982 | 1950 | 1066 | 1.85 | 1.5 | 93.09 | 3.5 | 0.06 C |
BNi-4, AMS 4779 | |||||
| Hi-Temp 932 For stainless steels, Ni, & Co base alloys with thin sections--jet engine parts and chemical equpment. For uses that demand high temp properties and good corrosion resistance at low processing temperatures. |

BNi-6 | ||||||||
| Hi-Temp 933 Often used for brazing honeycomb structures, thin-walled tube assemblies, and for nuclear applications where boron can't be used. The addition of chromium gives it better high temperature and corrosion properties than Hi-Temp 932. |
