I just googled "organ pipe metal" and got 1,000,000 hits. The first
half dozen talked about what you want.

Please log in for more thread options If you can roll out a block into a sheet or a rod into a sheet -
buy bulk solder. Tin-lead by percentages.
It comes in sticks and ingots. A electronic supply house can set up an order.
Or perhaps direct.
Look at a solder company. Tin lead.

Page 9 on the North American 2007 Recommended Electronics Assembly....
You will need a roller - and roll out a sheet as needed.
I'd take the bars and make smaller sheets.
It would be nice to have a chunk from an old one and have it analyzed
for the content % of material. Normally it is a simple and low cost test.
Inquire as to what is needed (match head likely) and price.

There's a multi-volume set on organ construction you might look up at
a larger library via interlibrary loan, apparently the proportions of
lead and tin have a fairly large effect on the sound of the pipes. The
higher the tin content, the better the sound, up to a point. Too high
a tin content and you get "tin disease" and the pipes will fall apart
with temperature change. I'm sure this alloy isn't available
commercially as sheet, it's relatively easy to make up, after all.
There are several books out there on past and present practice of pipe
construction, you need a stone table long as the longest pipe and
wider than the circumference of the widest one. A sliding trough is
used to cast the molten alloy as it's slid down the table. Different
thicknesses of sheet are used for the different pipe pitches. One
documentary on one of the cable channels showed constructors doing
this. Apparently wrought metal sounds different than cast. You could
use tin or brass sheet, but the sound would probably be more like a
whistle than an organ. For short stuff like you want, you could
probably knock together a sliding trough out of pine and use a
tombstone reject or maybe a cheap Chinese surface plate(almost the
same thing).

I've heard that a canvas-lined wooden tray works, although it didn't
for me using battery lead. I didn't have enough 50:50 solder to fill
the sliding box.
