Electrical Connection to aluminium substrate 1

[paulmech01]

I am trying to make an electrical connection between an electrical cable and aluminium, currently brass pins are soldered to the aluminium and the wire is soldered to the pin.

We need to move away from the solder used to join the brass pin to the aluminium as it contains lead, but no ther lead free alternatives available to join aluminium to brass.

Can somebody offer an alternative.

The core of the cable that is connected to the aluminium is tinned copper.
Could this be spot welded or induction or some other resistance weld joined to the aluminium.

The aluminuim is quite thin, Dia 12mm x 1mm wall.

Don't laugh, this stuff does work. The only problem I've had with it is the cost.

Is this just a consumables site.

What product do you mean exactly, the Super Alloy 1?

What is its composition, (ie silver, tin)?

What is the flux used with it made from?

I don't know whether the manufacture the stuff or as you just a distributor. I called the shop where it's being used and the people still there couldn't find the MSDS sheet for the material. They are just treating it as another brazing alloy by using a downdraft table for the majority of the work.

I don't know the composition but if their client list is anywhere near truthful there would not appear to have any
bad actors in the material.

I will call tomorrow as I need to get an MSDS for another shop that plans to use the material.
