Pro Tip: For best results, clean all surfaces before heating. Use flux on brass or dissimilar metals to prevent oxidation and ensure strong joints.
FAQ: Do I need flux with Sil-Can 5?
Not for copper-to-copper joints — it’s self-fluxing. For copper-to-brass or other metals, use a proper brazing flux.
FAQ: How is 5% silver different from 15%?
5% silver offers a good balance of cost and performance but has a slightly higher melting range and lower ductility than 15% silver alloys.
