copper alloy - need replacement for cancelled spec

copper alloy - need replacement for cancelled spec

(OP)
I am looking for a replacement material for UNS C63230 grade copper alloy.  From the info I have found, this is a cancelled spec.  What would a comparable current specification be?

Material composition as follows:
Manganese  0.07%
Silicon    0.10%
Tin        0.03%
Lead      <0.01%
Copper     81.6%
Zinc       0.27%
Nickel plus cobalt 4.72%
Iron       4.41%
Aluminum   8.77%

Thanks,

My suggestion is that a nickel aluminum bronze in the same general category like C63280 is most appropriate.  This alloy has somewhat higher Mn content.  Use the following link for more information:

TVP,
Thanks!  What effect would the higher Mn content have, if any?

What would be the difference in the characteristics between C63230 and C63280 due to the higher Mn content and the lack of Sn, Zn, and Si?

Hardness, corrosion properties, etc., etc.

Thanks,
Phil
