[Amps] how to recognize beryllium

[Dan Sawyer]

All, how can beryllium be recognized?

First: I know it is found in rf transistor tops; is it found in 
transistor mounts? An rf transistor mount has been scratched and needs 
to be resurfaced. The part is an mrf 150, however it would be 
interesting to know in general.

Second: I have a heat sink with 'heavy' heat spreader. What are common 
spreader alloys.

Third: Is care required to work with beryllium alloys?

Thanks,
