Zusammenfassung:	1404137 Sintered Cu-Ni alloy BRICO ENG Ltd 8 Nov 1972 [20 Nov 1971] 54012/71 Heading C7A A sintered copper nickel alloy consisting of, apart from impurities and trace elements:- has a non-homogeneous microstructure with Ni-rich and Cu-rich regions and may be made by mixing 80-50% of the mixture of a pre-alloy comprising the balance, apart from impurities, being Ni, with 20-50% of the mixture of copper powder, preferably adding a lubricant, pressing the mixture to give a compact which is then sintered at 1050-1100C for long enough that the Cu and pre-alloy only partly dissolve in one another.
