[Shop-talk] soldering/brazing aluminum tubing to steel tubing

    Interestingly, here is another version of pretty much the same chart... 
except this one says "No" to brazing aluminum and "carbon & low-alloy 
steels".

    As mentioned, rubber or silicone hoses would seem like a much better 
solution.
