UNITED STATES PATENT OFFICE DENTAL ALLOY Jakob Spanner, Nen-Isenburg, Germany, assignor, by mesne assignments, to Chemical Marketing Company Inc., New York, N. Y.
No Drawing. Application May 11, 1938, Serial No.
207,383. In Germany May 12, 1937 1 Claim. (01. 75-172) Objects of my invention are dental alloys which as are customary for casting alloys and solders. are particularly suited for casting and soldering Such additions are for instance copper, silver, zinc, purposes. cadmium, manganese, chromium, tin either singly The ordinary alloys with a low melting point or a mixture of two or more of them in similar such as are used for instance for soldering of quantities, for instance up to 10 or even up to 15%. dental prostheses consist chiefly of precious metals These metals have the effect of lowering the twhich may contain in some cases relatively small ing point of the alloys. additions of suitable non-precious metals. The The following are a number of examples which.
10 dental solders which are most commonly in use show compositions of alloys according to my inare for instance gold-, silver-, copper-alloys and vention:
palladium-silver-alloys with addition of such metals as zinc and cadmium. Example 1 Parts The objects or this invention are alloys with by weight relatively small contents of precious metals which Pd 45 1 m are par icularly suitable for the purposes of cast- Fe ins and soldering artificial dentures.
I have found that this purpose is served in an excellent mannerby the application of such alloys Example 2 as contain palladium as precious metal and metals 20 of the iron group as non-precious metals, the P 36- latter metals being used either singly or in com- Ni 58.0 bination of several of them. Cu 4.0
A dental alloy in accordance with my invention which is particularly useful consist for instance of Zn 1.5 u about 20-60 parts, in preference of about 30-45 parts by weight of palladium, the rest being iron, Example 3 nickel, cobalt either alone or in combination of Per cent two or more of the latter. y 2 5 2 Alloys of the described kind do not tarnish and Pd so are very resistant against the attack of agressive agents such as occur in the mouth. They further e N1 n Small quantities of M8- excel by the fact that they can be very easily cast, I What I claim is: they can easily be worked upon and are especially A dental alloy which consists of 20-60 percent suitable for soldering parts of metals which have of palladium, 4-15 percent of chromium and the u a high melting point forinstance-sucli which conremainder substantially all iron, said dental alloy sist of non-tarnishing steel such as are for inbeing characterized in being easily cast, tarnish stance known by the trade as vlA-steel or cobaltresistant. resistant against the attack or aggressive chromlum-tungsten-alloys such as are used for agents occurring in the mouth, and suitable for dental prostheses. soldering. o
