Brazing-beryllium, specialized process for unusual ...
Brazing-beryllium is well established because other joining techniques are less successful. Welded joints have low strength and ductility because of a brittle, coarse grained microstructure. A 38% Aluminum-Beryllium alloy is ductile and weldable , but can be brazed, although the filler metals should be based on zinc or aluminum, having lower brazing temperature than silver-copper alloys.

28-11-1995 · These and similar aluminum-beryllium alloys have low weight, high stiffness, high thermal transfer, a low coefficient of thermal expansion, high heat capacitance, a high fatigue strength and good corrosion protection. The industry presently uses the same processes for the brazing of aluminum-beryllium alloy parts as it uses for aluminum parts.
Beryllium - Wikipedia
Beryllium heeft maar één stabiel isotoop 9 Be. Onder invloed van de kosmische straling waaraan onze atmosfeer blootstaat wordt een kleine hoeveelheid van het radioactieve isotoop 10 Be gevormd. Dit proces is vergelijkbaar met de vorming van 14 C, maar 10 Be heeft een veel langere vervaltijd.Het kan daarom gebruikt worden om geologische processen zoals erosie en vorming van aardlagen te volgen.
Brazing - Wikipedia
Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much ...

Introduction to Furnace Brazing - Air Products & Chemicals
furnace brazing What is brazing? The term “brazing” can be applied to any process which joins metals (of the same or dissimilar composition) through the use of heat and a filler metal with a melting temperature above 840° F (450° C), but below the melting point of the metals being joined. In furnace brazing, temperatures of 2050° to 2100° F
