The following comparative descriptions are provided for braze materials in this guide to aid in the selection of a braze alloy for a specific application: Joint Strength n n Good: Recommended for low stress service conditions or where joint stress is not a factor. n n Excellent: Recommended for ser- vice conditions where joint stress is a primary design factor. Ductility n n Good: Recommended for service conditions where joint ductility is not a primary consideration or not a factor. n n Excellent: Recommended for ser- vice conditions where joint ductility is a primary design factor or for joints where extensive post-braze uploads/Geographie/ braze-material-guide-oerlikon.pdf
