Hello,
Have someone heard about this alloy?. It was designed to fit soda-lime glasses. I thought it would be of use in warmglass creations. Below this I quoted some links for what it's worth. Seek for Alloy 48

A known brand is NILO ALLOY 48 code UNS K94800. It's 48% Nickel 58% Fe. COE (20°C-300°C) --> 87.

No not heard of it
I wonder wheather it is a cold assembly type of thing
Rather like lead came is
Brian
There is a big problem with this kinda industrial stuff U often can only get it it U buy a ton or so

Hi Brian,
It's not a cold stuff but a special alloy designed to fit Soda-Lime-Silica glasses. It's for glass-to-metal seals. And yes, here in Argentina you have to buy a full spool of wire. I thought that up-there it would be easier to get two or three feet and try it in the kiln. According to the specifications it sounds a promising material.
Eureka? - Light bulbs lead-in wires

I think I have found that darn wire. Each incandescent light bulbs has two lead-in wires to feed electricity to the tungsten filament. According to
http://www.mgg-lamps.de/pdf/07E.pdf
these wires called "Dumet" should be compatible with glass (light bulbs are made with 90 COE glass). The wire composition is nickel-iron with some coating to improve sealing. More info on Dumet wire:

Well, Dumet wire is not exactly the same as Alloy48 but I think these are very interesting metals. I wonder whether I should take a hammer and go for a 150W light bulb to extirpate the lead-in wires and see... I'm affraid Graciela would defend it.

I'll take a guess and say that maybe it is the wire used to make wired glass. If you could get some, it might make interesting art between layers of glass.
I have seen wires fused between glass that were less than aesthetically pleasing. Figuring a technique to do that and get a nice look would surely be interesting.
Thin copper works. Heavy copper does not.

If U can use the correct words sometimes U can get a free sample
Do not use words like I am poor give me free stuff
Something like
I work on large artchitectural commissions using fuzed glass and I am researching new materials
Ur Aloy 48 sounds realy interesting 4 my application
Could I get a small sample from U 2 try
Some 20 years ago I wanted some tungsten carbide rod
After a lot of research I found a company
Called em up
I said please could I have some 2mm tungsten cardide rod
They said certainly how many tons did I want !!
Eventually they sent me some free samples
I am still using thrm today
