Definitions
- a monophase forging alloy containing less than 5% iron, less than 6% nickel, between 5 and manga nese, 1 to 7-%- aluminium and 0.01 to 0.2% arsenic, antimony or phosphorus,- balance copper.
- arsenic, antimony or phosphorus increase the corrosion resistance by preventing the aluminium from being extracted from the alloy.
- Such known alloy-s particularly have a composition of between 5 and 13% of manganese and experiments have been made with an alloy of 12% manganese.
- an alloy having 8.5% to 10% manganese, 8.5 to 10.5% aluminium, 2.5 to 5% iron, 2 to 3% nickel, less than 0.25% impurities such as zinc, lead and silicon, and the balance copper.
- Such alloys have a good resistance against corrosion and cavitation-erosioncorrosion in seawater.
- This invention is based upon the discovery that the corrosion resistance and particularly the resistance against cavitation-erosion-corrosion of such .alloys in seawater, particularlyat high. relative water speeds, may be improved at such known manganese contents (about 10 to 16%) while maintaining good mechanical characteristics such as tensile strength, 0.2-yield limit, total elongation, contraction at rupture and fatigue strength under rotated bending both in air and in seawater, without increase of melting point, and while maintaining a good weldability, deformability in hot condition and extrudability if such an alloy is manufactured with the following composition:
- Percent Iron 1 to 9 Nickel if desired entirely or in part replaced by cobalt 0 to 7 Aluminium 3 to 9 Nickel and iron together; 3 to 14 Manganese 10 to 16 Zinc 1 to 7 Balance copper and usual impurities.
- Zinc has a much lower melting point than manganese, which has lower aluminium equivalent than zinc, namely about 0.1 to 0.2. Thus less zinc than manganese is necessary for the same effect and zinc is not only more economical than manganese, but due to the low melting point of zinc it is possible to produce the melt more rapidly and with less heating energy, particularly with respect to final corrections of the bath.
- the surprising character of the present invention appears from the fact that up tonow in comparable alloys with relatively high managanese content no zinc was used at all, such as in the alloy given above with 1 to 5% iron, 1 to 6% nickel, 6 to 9% aluminium, 10 to 15% manganese, balance copper.
- B.$ 1400 1961: Schedule of Copper Alloy Ingots and Copper Alloy Castings, pages 65-68 for manganese-aluminium-copper alloys, to total absence of zinc is taken as a basis.
- Example 1 The following elements were melted together in a suitable furnace:
- the alloy was cast in a sand mold bonded by cement. Examination of a sample of this alloy gave the following values:
- Example II In a suitable furnace an alloy was made which obtained the following composition:
- Example III.-An alloy was made with the following composition:
- Example I V.-An alloy was made'with the following composition:
- Example V.-An alloy was made with the following composition
- Example VI.An alloy was made with the following composition:
- This alloy was with respect to its corrosion resistance and cavitation-erosion-corrosion resistance in seawater at a speed of 125 feet per second compared with the following known manganese-aluminium-cooper alloy: iron 2.74%, nickel 2.03%, aluminium 8.45%, manganese 12.04%, balance copper and impurities.
- Example VI the corrosion resistance of the alloy according to the invention, Example VI, was about 60% higher than of said known alloy.
- the cavitation-erosiou-corrosion resistance was about 100% better than of said known alloy.
- Example VII.An alloy was made with the following composition:
- the alloy was tested as indicated under Example VI and compared with the known alloy given in saidexample.
- the corrosion-resistance of the alloy accordingto the invention was about 15% better than of said known alloy.
- the cavitationerosion-corrosion resistance was also in this case about better than of said known alloy.
- Example VIIl.An alloy was made with the following composition:
- An alloy having the following weight composition: 1 to 9% iron, up to 7% of a member selected from the class consisting of nickel, cobalt, and mixtures thereof, 3 to 9% aluminum, 10 to 16% manganese, 1 to 7% zinc, balance essentially copper, the sum of the iron and any nickel being 3 to 14%, in which the aluminum equivalent, calculated by adding to the aluminum percentage 0.15 times the manganese percentage and 0.35 times the zinc percentage, is between 7 and 13.
- An alloy having the following weight composition: 2 to 7% iron, 1 to 5% of a member selected from the class consisting of nickel, cobalt, and mixtures thereof, 5 to 8% aluminum, 10 to 16% manganese, 1.6 to 5.5% zinc, balance essentially copper, in which the aluminum equivalent, calculated by adding to the aluminum percentage 0.15 times the manganese percentage and 0.35 times the zinc percentage, is between 7 and 13.
