Nickelbraze™ filler metals are used to join stainless steel, nickel and cobalt base alloys. They provide exceptional resistance to chemical corrosion and oxidation coupled with high strength at elevated temperatures. These alloys are widely used particularly within the aerospace, automotive and nuclear industries using vacuum or controlled atmosphere brazing methods. These products are available as pastes, powders or tapes. Several can be supplied in rapidly solidified foil form.
Nickel Based Brazing Filler Metals
Nickelbraze™ HTN1
Melting Range
980 - 1060°C
This general purpose nickel based brazing filler metal produces high strength, oxidation and corrosion resistant joints. It is used in highly stressed components and aero-engine applications.

EN1044:1999
NI101
Nickelbraze™ HTN1A
Melting Range
980 - 1070°C
Nickelbraze™ HTN1A has restricted carbon content and is used for similar applications to HTN1 such as aero-engine and nuclear components.

NI1A1
Nickelbraze™ HTN2
Melting Range
970 - 1000°C
This filler metal is the first choice for many applications except for very thin walled assemblies. Good alloy flow allows joint clearances of 0.025-0.1mm. Widely used for automotive EGR parts.

NI102
Nickelbraze™ HTN3
Melting Range
980 - 1040°C
Nickelbraze™ HTN3 is again similar to HTN1 but finds applications in marginal brazing atmospheres offering good flow where tight joint tolerances are encountered.

4778/BNi-3
EN1044:1999
NI103
Nickelbraze™ HTN4
Melting Range
980 - 1070°C
This alloy composition produces a wide melting range which can produce large, ductile fillets. It is suitable for brazing components where tight joint tolerances are not possible.

4779/BNi-4
EN1044:1999
NI104
Nickelbraze™ HTN5
Melting Range
1080 - 1135°C
This product is used for high strength, oxidation resistant joints that can operate at elevated temperatures. It is used in aerospace, automotive catalyst and heat exchanger applications.

BNi-6
EN1044:1999
NI106
Nickelbraze™ HTN7
This filler metal is used on thin walled structures and on high temperature components. It shows low erosion on iron and nickel alloys. Contact joint gaps are required.
AMS/AWS A5.8
BNi-7
EN1044:1999
NI107
Nickelbraze™ HTN61
This filler metal is widely used for automotive EGR components. It wets well on stainless steel, has good joint strength and offers good resistance to chemical attack.
