Aluminum / diecast automobile parts welding

Hello,
I am looking for the best weld procedures for welding some of these die cast aluminum automobile parts.
I think the parts have a mixture of tin, aluminum and magnesium. Any help or ideas will be very much appreciated.
Thanks,
Gary

Gary,
Welcome to the forum!
I have repaired a carburetor once with Crown Royal Kirkrod. Carburetors have a high zinc content and it worked for them. You have mentioned there is a mixture of tin, so I am not sure this will work, but you could give it a try. To give a better answer, what parts exactly are you wanting to weld? If it is a intake or something like that, this may not be the correct filler.
The major drawback is Kirkrod it VERY expensive for only one pound! I was also provided a junk carb to practice on before lighting up on the real thing. When it says it has a low melting point- it means it. It took some practice until I was ready for the real thing. Clean the material really good and don't breath this stuff.
Here are the specs provided by Crown.

I am very familiar with the aluminum rod, I use a boat load of it for repairing aluminum propellers. Works great as I have finally mastered the procedure after 30 years doing it for my business.
I did use this stuff for the repair of this automobile part. It was with 1/16"
Thanks for the replies.

i have done toyota, honda, ford, opel(gm) vauxhall (gm) saab, fiat oil pans and some cosworth cylinder heads, all done with 4047.
I like to preheat 150-400celsius, preheat burns off oil and contaminants, helps alot.
But the "thing" in my mind is the 4047 fillerrod, wets in so nice and can handle more porosity than 4043.
(ill do all cast alum parts with 4047)
Some times ill preheat "too hot" and let it cool some time before welding, just to burn off oil and crap out of the casting.

Thanks for all your replies!
This part is a steering wheel column part made of ZAMAK. It's off an old 1958 Cadillac. Was sent in from Sweden to be reworked by some old car buff restoration place. That's how I ended up with it
