Eutecrod 1600FC (Eutectic - Castolin)

Hi, I recently bought a quantity of Silver solder that came along with several boxes of " Eutecrod 1600FC " flux coated "silver bearing" 3/32" rods. I like to know what I'm using and have been unable to find anything out regarding these rods. Not surprising given the phone number on the boxes is " Feltham 6571". While the flux coating is in a pretty poor state, I did try one on a piece of copper using just a Primus 2000 propane torch and it flowed beautifully. Any information regarding the content / use for, these rods would be welcome, Thanks.

Couldn't find the 1600FC but find lots of others. Maybe a call to the supplier is in order..

One description was talking about annealing at 1600°F - coincidence perhaps?

Eutecrod is/was a tradename used by Castolin/Eutectic Company.

1600 is described on page 72 of their data book as a high temperature, wide melting range, low silver content alloy. This book came into my posession in the early 70's when I worked for Johnson Matthey.

The information indicates to me that it is an alloy that cannot be neither sold legally nor "placed on the market" (ie given away) legally..

I would not expect it to have the brazing characteristics you have described. It doesn't do what it says on the tin!

Leave it with you. You seem to have bought a "pig in a poke!" Worse case scenario is that it could shorten your life expectancy.

Bargain?
