Silicone copper bronze MIG wire for cast iron and dissimilar metals

[OllyO]

Hi all,
Does anyone have any experience using the above MIG wire?
I'm interested to see if it could be used on thin cast iron repairs/ welding steel to cast iron.
I know the lower melting point of the filler facilitates use of lower heat on machine and perhaps coupled with some preheat this could prove effective?
I generally use ferro nickel MMA or braze but am interested to try this wire just out of interest really

Have just come across the article on this site detailing cast iron repairs using the above filler wire with MIG
Would still be interested to read anyone else's thoughts

never tried migging c.i. but the roll of wire would cost a lot,ok if you have a lot to do.

SILICON - a metallic element

SILICONE - an elastomer sticky gunge to seal your bath with

Quite important to get the right one

@malcolm wrote the original article I believe.

Not too sure but he might be able to help you out

Ha ha, that'll be why the weld didn't hold then!

Nick- 90% of my work is CI so worth investing in if good process. Spool looks like £200 ish so would work out cheaper than box of nik sticks I reckon
