Has 1050 rod been replaced by 1070???
- Thread starter gatesy
- Start date
I don't think it's replaced it, at least not across the board but if it was the case then we're only talking a change from 99.5% ally to 99.7%. Some (most?) manufacturers still list 1050, others don't- my usual source used to supply 1050 SIF now it's ESAB 1070. The only 1xxx wire EWM list is 1450 which is Ti stabilised, thread on it here... http://www.mig-welding.co.uk/forum/showthread.php?t=29036
Commercially pure aluminooom in the US is usually/most commonly 1100 AFAIK.
All the 1xxx series are a min of 99% ally, the last two numbers (only for the 1xxx series) denote fractional purity beyond 99.0%. The second digit refers to modifications, i'm guessing in the case of 1xxx what's permisible with regards to the remaining impurities?
As far as i've been able to work out for the common alloys...
we have 1050 where they have 1100
we have 3103, they have 3003
we have 5251 they have 5052
we have 6082 they have 6061
what we call 7020 they call 7005
I think everything else is about the same i.e. we both use 5083 and 2024

Thats the same as I had, Asked for 1050 SIF and got quoted for 1070 ESAB, although I do have an old carton of ESAB that is 1050!!!! I did see 1070 in one catalogue that in the description also had 1050!!! Seeing as I do a fair bit of fuel tank work and have always used 1050 I was wanting to make sure 1070 would be ok. Could the change from 1050 to 1070 be because the manufacturers are finder their material is more pure, as the 99.5 and 99.7 are minimum percentages????

I suppose it could be they just changed the designation as they're consistantly hitting a min of 99.7% purity these days. The ESAB group bought or merged with AlcoTec some years back and as i understand it AlcoTec used to be part of Alcoa (one of, if not the biggest ally producers in the world). It'll be good wire. SIF are probably not much more than a brand name nowdays? It's come up before when discussing some of the 'speciality' wires and electrodes that most of 'em are just rebranded regular stuff with a fancy name and a price tag to suit
