[sdiy] Soldering to Aluminum

[karl dalen]

I could'nt believe my eyes on what Ken wrote so I tried it out
yesterday, and,, no it didnt work out, i sugest that still
aluminium have a higher melting point, i underdstand that
the whole idea is about tinning the surface of the objects
before joining them with a solid tinn joint! 

What a dissapointment! :-(

Perhaps you used a torch Ken! 
Or perhaps i didt all the way wrong!!

I know that there are some flusses wich are used for
soldering aluminium and stailess steels but oil didt do it!
I have read that a typical alu solder contains: 18% tin, 80% 
lead and 2% silver and requires higher temp then a typical
soldeing iron can give!
