Description
Patented July 2, 1935 UNITED STATES PATENT OFFICE 2,006,598 7 CORROSION-RESISTANT AND MAILEABLE ALLOY No Drawing. Application June 30, 1933, Serial Claims.
This invention relates to corrosion-resistant and malleable alloys.
Gamma brass, that is to say, copper-zinc-alloys containing from 31 to 40% of copper, are known in the literature. Such alloys are distinguished by a low copper content, and are more corrosion-resistant than the generally used brass alloys of high copper content of the alpha and alpha+beta fields, and containing for example, 68 to 72% of-copper. It is however, impossible to employ the gamma alloys, poor in copper, industrially, since these alloys are extraordinarily hard and brittle, and can therefore not be worked.
The surprising observation has now been made in accordance with the present invention, that by the addition of a few per cent of a metal soluble in gamma brass, such as nickel or more advantageously cobalt-the amount of the added metal lying within the solubility limits in gamma 'brassand advantageously by the simultaneous addition of nickel and cobalt, alloys-are obtained which exhibit the excellent anti-corrosion propv erties of the gamma alloys, but which are admirably adapted to be mechanically worked.
Alloys are particularly useful which contain said additional metal in amounts below that is to say, for example, alloys containing less than 10% of cobalt or less than 10% of cobalt and nickel jointly. The simultaneous employment of cobalt and nickel enables the same eilects to be obtained with a substantially smaller cobalt con- In Austria July 8, 1932 (1) 38 to 33% of copper 3 to 8% of cobalt Remainder zinc.
(2) 3a to 32% of copper 4 to 9% of nickel Remainder zinc.
(3) 38 to 33% of copper 1 to 6%-of cobalt Approximately 4% of nickel Remainder zinc.
What we claim is:
1. Corrosion-resistant, mechanically workable alloys which consist substantially of a copperzinc alloy containing copper in an amount corresponding to gamma-brass and an addition of from 3 to 10 percent of one of the elements cobalt and nickel.
2. Corrosion-resistant, mechanically workable alloys according to claim L'containing at least 5 to 6 percent of cobalt.
3. Corrosion-resistant, mechanically workable alloys according to claim 1, containing at least '7 to 8 percent of nickel.
4. Corrosion-resistant, mechanically workable alloy having the following composition:
Copper 33 to 38% Cobalt 3 to 8% Zinc Remainder 5. Corrosion-resistant, mechanically workable alloyhaving the following composition:v
Copper 32 to 38% Nickel 4 to 9% Zinc Remainder WOLF JOHANNES MULLER.
