The identity of Ampco 18 as UNS C95400 is even advertised in old Ampco pamphlets which I still have.-- Yannick 23:30, 22 October 2007 (UTC) [ reply ] And actually Ampco 18 isn't even a proper material specification, because it only offers nominal values without tolerances rather than minimum requirements.
A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%.

Ampco-Pittsburgh Corporation (American Metal Products Company) is a specialty steel manufacturer headquartered in Downtown Pittsburgh, Pennsylvania. [3] It is one of several companies to bear the Ampco name, and it should not be confused with the Milwaukee-based copper base alloy producer, Ampco Metal Inc.; the Miami-based cabinetry company; the Swiss aluminum corporation; or the Dallas-based ...
BAg-27, Easy-Flo 25, Silvaloy 25. Similar to BAg-2a, more economical due to lower silver content; higher melting point and melting range results. For steel, stainless steel, copper, copper alloys, nickel, nickel alloys, and combinations. Melts through mushy state. For larger gaps, where fillets are desired and clearances are not uniform.
Aside from the basic 25% silver to 75% copper mix, combinations as divergent as 5% silver to 95% copper are also marketed as "shibuichi". [1] A wide range of colours can be achieved using the whole range of alloy compositions, even above 50% silver, e.g. 90% copper and 10% silver for a dark grey and down to 70% copper and 30% silver for lighter greys.
Piggot states the brass used for machinery and locomotives in England was composed of copper 74.5%, zinc 25%, and lead 0.5%, which would make it a tombac according to Ure. [6] Piggot's own definition of tombak is problematic at best: "red brass, or tombak, as it is called by some, has a great preponderance of copper, from 5 ounces of zinc down ...
