Hi all,
Once again I would need your light. Really, I received an antenna drawing (which will go to space) made of Hard Brass. I have to perform some mechanical and thermal analysis and I had a look in my book to get the mechanical properties but I have data for the following:
Red Brass (85% Cu), Low Brass (80% Cu), Copper Brass (70% Cu) and Yellow Brass (65% Cu) but nothing about Hard Brass... Does anyone know what is the copper content of Hard Brass?
Finally, I know that Brass is TVAC compatible but I am wondering if there is some constraint while using this material (apart from corrosion cracking which I am aware of) since this is the first time I have seen it on a flight hardware.
Best regards,
Franck
