Really, I thought steel can be either Iron or Aluminium as CAST is a combination of Carbon, Alloy, Stainless and Tool?

Wut? There's nothing cast about it.There's no alloy either, you know how expensive that'd be? lol

It's regular carbon content steel, sheet steel pressed & welded together.

Right. I didn't think about the price of it. Yes true.
One welder told me that it has either cast Fe or cast Al, so he is wrong indeed.

Cast iron is traditionally very strong, but is brittle when stressed. Hence hub & control arms can be made from it, but not long structures like a chassis. The chassis needs to be able to flex or 'elastically' deform/reform as they call it. Plus a cast iron chassis would weigh a ton.

Aluminium is much the same, flex it & it'll snap where steel will bend.

A ton for a chassis, sh*t, by the time you put on the rest of the body you'd have one heavy car

Appreciate your explanation very much Bennoz. This stupid welder asked that stupid question. He claims that he has 30 years of welding exp.

There is a small (3") crack on the chassis. That's what needed repair.

Gumtree is not a problem mate. Search around. This is not the first time I use Gumtree.

From memory you have to super-heat the entire cast to stop that?
Not a welder, so not certain..

Assuming you're trying to weld mild steel to it?

Mild steel to Cast Iron is very low carbon to very high carbon steel. The weld pool will have high cooling rates, resulting in a brittle weld, prone to cracking. If you really need to bodge something up, you really have to preheat the CI.

The only recommended method to welding something to CI is brazing - so you don't disrupt the metallurgy of the CI. It's almost like gluing something to it. Not something you'd use on a high stress application.
