COPPER ALLOY.
No Drawing.
This invention relates to a method for in- I creasing the hardness and elastic limit of copper alloys containing a predominant pro-- portion of copper, the particular alloy of the present case, however, relating particularly to a copper alloy containing silicon an manganese.
An important result, whichgcan be obtained with the use of my invention is that the hardening of manganese. silicon andcopper alloys may be effected'by. temperatures of about 200 to 400 C. and such alloys may be used to replace the expensive tin-alloys used for bearing-liners.
The following contains some examples 'of alloys suitable for this purpose.
An alloy consisting of 80.9% of copper. 15% manganese, 2% of iron and 2.1% of silicon after being forged and annealed'at 525 C. and cooled has a hardness of 195, and after exposure to a temperature of 215 C. for 24 hours has ahardness of 205 and after this treatment for 60 hours the hardness of 274. p
An alloy consisting of 81% of copper, 14% managese, 2% iron and 3% silicon cast in sand, shows a hardness of 11.7, and after exposure for 36 hours at a temperature of 215 C. has a hardness of 152, and after this treat ment for 96 hours, the hardness was 174.
An alloy consisting of 80.6% copper, 15% "p manganese, 1% iron and 3.4% silicon. after being forged and annealed at 600 C. has a hardness of 178, and after exposure for 36 hours at a temperature of 215 C. the hard ness of 249. l 1
An alloy consisting of 77% of copper, 14% manganese, 3% iron and 6% silicon, cast in sand, shows a hardness of 170, and after exposure for 24 hours at a temperature of 215 C. has a hardness of 222.
An alloy consisting of 82% of copper, 13%
of manganese, 2% of iron and 3% of silicon,
castin" sand, shows a hardness of 138, and after exposure for 8 hours at atemperature of 350 C. has a hardness of 287.
Application filed J'u1y17, 1926. Serial No. 123,250.
The essential feature of this invention is not affected by the addition of other metals to the alloys described above, for example zinc, nickel or lead may be present. The presence of suchadditions only afiects the hardening temperature and in' some cases makes the alloys more easily cast.
Now what I claim is: v A
1. The method of increasing the hardness.
and elastic limit of alloys containing a predominant proportion of copper, 0.5 to 20% manganese and 0.3 to 8% silicon, which consists in subjecting the alloys, after they have been cast, rolled or forged, to a prolonged heating at a temperature of about 200 to 350 C.
2. The method of increasing the hardness and elastic limit of alloys containing a predominant proportion of copper, 2 to 25% of manganese, and 0.3 to 8% of silicon, which consists in subjecting the alloys, after they have been cast, rolled or forged, to a prolonged heating at a temperature of about 200 to 350 C. i
3. The method of increasing the hardness and elastic limit of alloys containing a predominant proportion of copper, 0.5 to 20% of manganese, 0.3 to8% of silicon, which consists in first nnealing the alloys after they have been ca t, rolled or forged, at a temerature above 450 C., then cooling and finally hardening the same at a temperature of from 200 to 350 C.
4. The method of increasing the hardness and elastic limit of alloys containing a predominant proportion of copper, 0.5 to 20% manganese, 0.3 to 8% silicon and zinc up to 10%, which consists in subjecting the alloys after they have been cast at a temperature of from 200 to 350 C.
In testimony whereof I signature.
hereunto afiix my DR. FRIEDRICIT HEUSLER.
