[TheForge] Bronze casting

I may have forgotten to mention that I'm in the UK. We can't just pop down
to Walmart and pick up some Naval bronze, you know! After a brief trawl
around, the bronzes I can easily get hold of are a phosphor bronze

Cu  %  REM        Ni  %  0.10 max.
Sn  %  10.0-11.5  Fe  %  0.10 max.
Zn  %  0.05 max.  Si  %  0.02 max.
Pb  %  0.25 max.  S   %  0.05 max.
P   %  0.50-1.00

or a nickel aluminium bronze

        Al    Fe   Ni   Mn   Si   Sn   Pb    Zn   other
% min.  8.5   4.0  4.0  -    -    -    -     -    -
% max.  10.0  5.5  5.5  0.5  0.1  0.1  0.05  0.4  0.05

(which 'meets Admiralty standards!')

I'd be interested in giving this a go - are either of these worth trying?

Thanks for the help so far,

Rich.
