fields metal
« on: October 10, 2009, 12:45:28 PM »
i've found out about fields metal!!

my grandad used some of this stuff in sixties, i can remember him telling me about this metal they used to fill gaps, he swore it was melted with hot water.
too my shame, i didn't believe him :( :( :(

i've found out about it now, melts at 61 deg, is not soft like lead.

anyone used this stuff?

its 576 +vat a kilo :doh: :doh: :doh: :doh: :doh:
if i'd thought it through, i'd have never tried it

Commonly known in this country as Cerrobend, but not a filler, but an aid to bending, and I think it contains a large amount of antimony.

I used it when working at R-R to help bend up custom SS window frames.

It is now known under another name that you can buy it under, but unfortunately I can't recall what it is.

I can say though, it is nowhere near the price you have quoted.

Yes Cerrobend is the stuff, we use to use it to take casts of die forms to check them on a projector.

When I finally get to make  my boiler for my loco I'd like to try making some stainless steel supper heating tubes they need a tight 360 bend that I'll try doing with cerrobend.

Cheers

The one I know is called Wood's metal. Info here, along with similar types including Cerrobend. http://en.wikipedia.org/wiki/Wood%27s_metal

Wood's metal available here - http://www.tiranti.co.uk/product.asp?Product=1494
From probably the smallest, dampest and most untidy workshop in Bradford, West Yorks, England, if not the world..

Thanks for the links lads.

Tiranti, I never thought about them, but should have. I used to use them years ago for silicone mould material.

Looks like I got the formula wrong, but it is for doing exactly the same job as the more expensive one if you are bending tubes etc.

If you go to Mc Master-Carr and look up the cerrobend  they list and sell a number of assorted working temperature alloys of it form the cheap stuff to the exotic.

http://www.mcmaster.com/#cerro-alloys/=40g368

They list the info on some real low temp alloys.
They don't ship out of the US any more Home land etc. but they will give you the info to find it locally
