The performance of a brazed joint depends on various factors, including the properties of the base materials, jointdesign, and the metallurgical interaction between the base metal and the filler metal.
To achieve maximum joint strength, an optimal joint clearance of 0.003 to 0.005 inches (0.076–0.127 mm) on each sideis recommended.
Even with wider gaps, sufficient strength can still be achieved depending on the final operating conditions.
Compared to other commercially available soft solders, zinc-based brazing alloys offer the highest strength. Whenproper joint design techniques are applied, their shear strength can typically exceed 18,000 PSI.

Post-braze cleaning of flux-cored bong da truc tiep hom nay brazing rod
Cesium-based flux and its residues are non-hygroscopic and non-corrosive, so post-braze cleaning is usually notrequired.
If cleaning is needed, use a 50/50 mixture of nitric acid and distilled water. Parts can be immersed and gentlyagitated if necessary.

How to store bong da truc tiep hom nay brazing rods with flux
Chalco guarantees a shelf life of 90 days from the shipping date when AL 822 is stored in its original, unopenedpackaging.
Ideal storage conditions are 65–75°F (18–24°C) in a clean, dry environment. If separation occurs, the brazing pastemay need to be remixed for consistency.
In practice, if no issues arise, the product can often be used beyond the 90-day period.
Flux-cored wire, when properly stored, can maintain full functionality for up to 2 years.
