aluminum to steel?

Two words.......... Galvanic corrosion.

what about using like a keystone repop of the stocker? wouldnt it be steel?

I have seen it done before in the semi trailer industry. A local company had a custom product for flatbed trailers that they sold and installed. The product was aluminum.. so when it came to instaling on a steel trailer they had what they called a bimetal. It was a strip that was half steel and half aluminum. Both sides were weldable.

aluminum foil tape...duh

my boss went to a welding show were they were showing off new products and I am almost certain he mention a welder that can weld aluminum to steel,  but it cost like $15,000 or something ridiculis like that. It was a mig and tig in one. But again I am not shure.He did bring back some pop cans that were fully welded together by the same welder that was pretty dam cool.

if your that worried about the galvanic corrosion then use panel bond to bond a thin sheet of abs to the hood then bond the other part to the abs. the abs will act as an insulator between the 2.

There's some stuff you can get at boat shops called Tech Bond.  It's supposed to bond pretty much anything to anything else. supposedly you can even drill and tap it.  Still hfta do soething for the corrosion.

--------------------------------------------- Originally posted by standardbyker88 what about using like a keystone repop of the stocker? wouldnt it be steel? --------------------------------------------- that would be seriously the best way to go about this.  my stock hood is aluminum and i have an aftermarket oem replacement hood that is steel.  aftermarket companies are all about the cheapest way to copy and sell a factory part so they generally use steel over aluminum.  call your local aftermarket parts store (like keystone) and ask them. if they dont know, go down there with a magnet and ask to see one!   aside from that i also like the idea someone said about takin the steel part to someone and having the shape made in aluminum.   you could mess around with glues and bondo and glass which all will technically work, but it just depends on how well you want it to last.

Hey man, I am not sure on that year F-150, but i was able to get a stock hood on mine with a little motor mount work and doing a different air cleaner arrangement.  Also I like the aftermarket steel cowl hood idea, that would use esentially no filler. Good luck to my fellow F-150 brethren. JR

JR --------------------------------------------- my truck is a 97 but the whole front is a 2000 style. my hood is a stock hood just aftermarket. before we bodydropped it my friend rearended someone in it thats the only reason i got new sheet metal. i just have an aftermarket intake and trim some of the ribs inside the hood. (sorry didnt mean to make this about my truck!) but yeah i think just find a steel hood or a steel cowl.
