Turbo Braze supplies aluminum brazing alloys in paste, powder, wire and preforms. The most commonly used aluminum brazing alloy is our 718 alloy, which offers the best combination of melting temperature, joint strength, versatility and corrosion resistance.

716 BAlSi-3 4145 86 10 4 CU 970 521 1085 585 INFO
This filler metal is a general-purpose aluminum brazing alloy suitable for joining most aluminum alloys. It is also suitable for use when joining titanium, aluminum-copper and aluminum-copper-silicon, although consideration must be given to the potential for galvanic corrosion when brazing dissimilar metals. 716 has a wider melting range than the 718 brazing alloy which makes it useful for applications where large or inconsistent joints are common.

718 BAlSi-4 4185 88 12 - 1070 577 1080 582 INFO
This filler metal is a the most commonly used aluminum brazing alloy. It is suitable for joining all brazeable aluminum alloys using all common heating methods. This alloy is quite fluid when molten and exhibits excellent penetration of brazed joints. Color: Silver-Gray
Specific Gravity: 2.66
Density: .096 lb/in3
Electrical Conductivity: 41% IACS
Electrical Resistivity: -
719   76 10 4 Cu, 10 Zn 960 516 1040 560 INFO
This filler metal is suitable for joining most brazeable aluminum alloys when using flux. It is not suitable for vacuum brazing because of the potential to vaporize zinc. Has poorer corrosion resistance than either 716 or 718. Color: Silver-Gray
Specific Gravity: 2.91
Density: .105 lb/in3
Electrical Conductivity: 41% IACS
Electrical Resistivity: -
