source of silver solder other than BOC?
Folks,
I've moved house and a large amount of my shed is packed into a storage container whilst I get the house sorted out, and look at shed erection/construction.
As a result I will need to grab some silver solder for a few small jobs coming up.
Last time I bought Silver solder was through BOC and it was quite expensive... is there a cheaper source of silver solder in Oz?
I'd be chasing 2-3 rods suitable for brass, copper, steel, etc - ie general construction use - not jewellry
I now live in the Perth area, so the big green shed, coventries, and other stores are at most 2 hours drive - most around 1 hour drive.
if you can suggest a source, and grade of silver braze I'd appreciate it.. I do have my flux available (Sil Braze? - the one from BOC in the small balck jar), but no rods.
Many thanks,
Des

Des.
Most good Industrial suppliers usually have it by the stick. 45% seems to be pretty general purpose.

plumbing stores Reece etc, refrigeration wholesalers, Actrol, Heatcraft would all have it
keep away from anything less than 15% silver brown tip...this is good for copper..no flux if clean copper
if you want to do steel to copper then 45% Blue tip..needs flux
both will do copper to brass with flux

One thing I found was the last time I bought some the local welding supply place sold me the non-cadmium bearing 45% silver brazing alloy. It is OK but a slightly higher melting point and not as good on bonding to steel (from my novice perspective)
Thus I'd be asking for the old 245SBA - cadmium bearing, 45% silver --- this is of course provided the job does not involve water or food handling equipment/utensils.
From the modelling magazines, it would seem the cadmium bearing alloys are now much less available in the UK than previously -- Reeves ran a series of advertisements saying "this is the last batch"
Added Link: SBA - Victoria include cadmium bearing alloys and have a "contact us" page.Last edited by HavinaGo; 29th August 2012 at 06:36 PM. Reason: added link to australian supplier of cadmium bearing alloys
cheers

definitely need steel to steel in the first job on the "to do" list.. so that limits me to 45% then
I'll keep hunting around the local area before heading to Perth
Thanks for the heads up on the 15% stuff because the local plumbing place offered that, and the "big green shed" dropped the calls each time I was transferred around the store between tool shop and plumbing.
Thanks all,
Des

Des,
You could try Gentronics in Welshpool, they handle a lot of welding / brazing stuff, prices can be a bit hit and miss though. Alan.
