AL 822. High-strength, low-temperature. For aluminium-to-aluminium and aluminium-to-copper. 78: 22: Ag 72 Zn 28: 710/730 [8] – Ag72Zn. Ammonia-resistant. For joining ferrous and non-ferrous metals (steel, copper, brass...). Good flow properties. With stainless steel in humid environments risk of interfacial corrosion.
Brazing has many advantages over other metal-joining techniques, such as welding. Since brazing does not melt the base metal of the joint, it allows much tighter control over tolerances and produces a clean joint without the need for secondary finishing. Additionally, dissimilar metals and non-metals (i.e. metalized ceramics) can be brazed. [2]
Glidcop has also been used in hybrid circuit packages due to its compatibility with high temperature brazing, [3] and in particle accelerator components, such as radio frequency quadrupoles and compact X-ray absorbers for undulator beam lines, where the alloy may be subjected to high temperatures and high radiation simultaneously.
Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion.

Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil .
