Yup, http://www.ati-intl.com/alumsold.htm, Kester make the stuff too. 
Tin/zinc solder that melts
at 390 C, used with special flux. I've had zero success with the stuff but 
I probably gave up too
quick.
I use cold weld compounds for joining aluminum because they are so much 
easier. J-B Weld
is the best http://www.jbweld.net/ . I've used Pro Weld too.
