New developments in braze-joining are presented. This technology will extend practical utilization of beryllium in fabrication of lightweight, exceptionally stiff components.
Consideration of structural beryllium brazements is discussed. Some examples are monocoque cylindrical and conical shapes, radiator assemblies, sheet metal brackets, and sandwich structures.
Beryllium exhibits attractive properties up to 1200 F. Special fabrication techniques are necessary, however, due to its metallurgical and mechanical peculiarities.
Data presented show the effect of filler metal interactions on stress levels attainable in properly brazed joints.
Beryllium is extremely versatile and is an unparalleled material of construction where strength/weight at elevated temperature is the criterion.
