i just found out there is no cupronickel in gensis. it was not common in the west, but known as white copper in east asia.
it is used in coinage as well as shipbuilding for it's strength and high resistance to corrosion. so i suggest adding it as mid-grade warfare metal.roughly 2:1 copper nickel ratio could make it on par with bronze(heavier).
Hmm... these seems to be 90:10 and 75:25 CuNi versions. In Finland the alloy is called alpakka (trademarks Alpaka or Alpacca).
I should give it a go. Too bad nickel only appears in Gabbro, and way too many of my embarks have been galena-sphalerite-platinum awfulness (no copper no bronze no iron). I'll research if there's more nickel ores.
I found that CuNi is 8.8 to 8.9 density, same as black bronze. I gave it a tiny bit better edge than copper. Copper value 7, CuNi 9.

Can you find the relevant numbers from booklet at
http://www.copper.org/applications/cuni/txt_DKI.html"Homogeneous Cu-Ni alloys are difficult to machine. As a result of their great toughness, their machinability is poor, especially in the soft condition."
"The main ore of nickel in Australia (and in terms of worldwide production) is the primary sulphide mineral pentlandite (Fe, Ni)9S8, which occurs with pyrrhotite (FenSn+1), pyrite (FeS), and chalcopyrite (CuFeS2) in lodes in mafic and ultramafic (iron and magnesium-rich) igneous rocks. In Australia, nickeliferous sulphide ores and their host rocks mainly form parts of ancient volcanic lavaflows. However, most of the world's known resources are contained in nickel-bearing laterites (such as in New Caledonia and Cuba) in minerals such as garnierite ((Ni, Mg)SiO3.nH2O) and nickeliferous limonite which is nickel mixed with hydrated iron oxide."
