MINOR METALS 355

 W. P. Sykes, of Cleveland Wire Works (General Electric), and C. P. Miller,
of Romley, England, have developed a new cutting alloy composed of cobalt,
tungsten, and iron, which is intermediate in properties and price (probably
$4 a pound) between ordinary highspeed steel and cemented carbides. Konel
metal, a platinum substitute, and Kanthal metal, for electrical resistances,
are relatively new alloys containing considerable cobalt.
 Imports.—The imports of cobalt ore, cobalt metal, and oxide have declined
steadily since 1929, the apparent domestic supply of cobalt, as indicated
by the imports, shrinking in 1932 to scarcely more than one fourth what it
was 3 years earlier. The increased imports of cobalt sulphate~and~" other
salts" in 1932 can doubtless be attributed to the reduction in European prices;
it will be noted that the average declared value (foreign market value) of
the imports of sulphate was 23~ cents a pound in 1932 compared with 33 cents
in 1931 and 57~ cents in 1929.

THE INDUSTRY IN FOREIGN COUNTRIES

 The principal source of the ~iorld's rather meager supply of cobalt has
shifted from Europe to New Caledonia,, to Canada, and then to the Belgian
Congo. At .the, end of 1932 the Belgian Congo and.

Canada were stifi the main sources, but there is the possibility of a large
new supply—probably sufficient at least to double the present total
annual output—as a byproduct from copper smelting in Rhodesia. Certain
Rhodesian ores are unofficially reported to contain 0.15 percent of recoverable
cobalt, which may be obtained from the converter slag. A prospective increase
in supply, so far exceeding any
