To bond metal to metal, what would you use?

[Acheron]

Bonding a piece of metal to a cylinder head, only a small piece about the size of a 5p.

Epoxy resin? (this might also come in handy for the hole in my radiator) or some other substance?

[YoungOne]

Epoxy probably not good with heat.

[Globs]

A welder?
Or drill, tap and bolt.

Belzona 1111 super metal, if you don't go with 1111 they will have another product to suit.

I'd solder it

But i've got the kit to do that

When getting your jb weld pick up some k-seal for your rad, if it's only a pinhole.

If it's aluminum, I wouldn't bother.

Tiger Seal. Evil stuff.

Belzona is fantastic stuff, when we rebuilt the tractor engine, the recesses in the block that the O-rings at the base of the liners sit in had rusted away, resulting in the water running straight into the oil.
We moulded and rebuilt the recesses out of belzona. TBH I was only half expecting it to last more than 5 minutes, but 6 years on its still fine!

Chemical metal.

isn't chemical metal just ordinary plastic pudding with metallic filler materials ?

[Liquid Knight]

I've used it as a "get me home" repair on a cracked exhaust manifold before and forgotten about it for a month. It's a higher temprature compount than the usual fillers and bondo type products. You can get a VHT version as well.

This is excellent stuff. I've used it on heads, sumps and pressurised oil feeds (To block off a broken one). Highly recommended for pressure/Temperature applications. The fitting is threaded in but the top 1/2 of the thread had broken away, for over half the depth and that meant there was no sealing face.

The discharge from between a hookers legs? Surely quite sticky...

Epoxy resin (Araldite, Devcon, Etc.) softens with heat, so probably not good for cylinder heads or radiators.
