You can try http://www.cerromb.com on 44 1473 252127. It is known as
MB1 in the UK (UNS No. 87500). Min quantity is 250kg. Let me know if
they can't supply you, and I can have another look.

Try asking for it by the UNS designation of C87500 (silicon brass).
According to the Woldman's Engineering Alloys book it is a tradename
for a copper alloy containing 13% zinc and 4% silicon.
However, a quick look on google showed there is also a White Tombasil
that is another alloy, C99700.
Fine. Perhaps you could reveal where to find a list of these EN
designations somewhere at a web site. The only description I have seen
at http://www.copper.org/standard/euronumb.htm does not give the
composition range tables.
