Patented May 17, 1932 UNITED STATES PATENT OFFICE HARRY s. REKM, JR, AND FRANK a. HEIN, or DOVER, OHIO, nssrenons 'ro SHENANGO PENN MOLD COMPANY, or PITTSBURGH, PENNSYLVANIA, A. CORPORATION OF PENNSYLVANIA Our invention consists in a new and useful improvement in alloys, and is designed to produce a non-ferrous alloy for galvanlzlng,
which is' added to the molten galvanizing 'in that it affords the metal adequate protection against the action of atmospheric corrosion in the same degree as any other galvanizing coating. That feature of our invention causes the cost of galvanizing to be materially reduced as less spelter is used. This fact has been proven in actual commercial production. Moreover, our alloy causes the deposited coat to bright, clean and free from dross. The spangles are large which is highly desirable. In general, by the ad dition of our alloy to the spelter 'bath a superior coat is obtained at a greatly reduced cost.
Our alloy has, a fluxing action on the spelter bath causing the thinner coat, than ordinary, to be deposited on the material being galvanized. The fact that our alloy cleans the bath causes the deposited ooat to be uniform. Comparisons have been made, by observing the product coming through the gal-- vanizing pot containing ordinary spelter. The material was. Weighedv before and after galvanizing and the weight of the coating noted. Our alloy was then added to the bath. .Improved results began toshow. at
once, improvement continuing as the alloy worked. through the pot. The material was weighed before and after galvanizing, asv
before, and showed that a lighter coating was being deposited after the alloy was added to the bath. In addition, the material was cleaner and had a much'better surface appearance. The coating, even though'thinner,'was much more lasting in that it adheres pearance of the ALLOY Application filed May 5, 1931. Serial No.'585,802.
more closely to the metal surface of the material being treated. The savingin weight of spelter, after adding our alloy, more than pays for the additional cost of the alloy. In addition, there is the improvement in the apga'lvanized material by reason of the use of our alloy.
Our alloy contains the following components nickel, copper, iron, tin and zlnc.
lVhile we have hereinafter fully described one specific embodiment of our invention, it is tobe distinctly understood that we do not consider ouriinvention limited to said specific embodiment, but refer for its scope to the claims appended hereto.
A method of producing our improved alloy is as follows: We melt Monel metal which contains approximately 67% nickel, 26% copper, 3% iron, 4% balance manganese, carbon and silicon. The Monel metal constitutes 40% of our alloy. We then add to the molten Monel metal 30% tinand then 30% zinc. The bath is stirred to insure proper 1 components, but that the most effective combination is approximately 26% nickel, 13% copper, 1% iron,'30% tin and 30% zinc.
It is to be particularly noted-that zinc is added to our alloy toreduce the melting point. The temperature of the spelter bath is from 900 to 1000 F. The melting point of Monel metal is 2400 the tin reduces the melting point somewhat,
but tin is too expensive a metal to add more than is necessary. The addition of zinc brings the melting point to be1ow'900 F. At. this temperature, the alloy dissolves readily in the spelter bath, and also the presence F. The addition of of zinc in our alloy aids the alloy to mix more readily with the spelter.
It has been found, by actual test, that 1 part alloy, by weight, added to the galvanizing bath for each 100 parts of spelter produces the desired results.
Having described our invention, what we claim is:
1. An alloy composed of 26%nickel, 13% copper, 1% iron, tin and 30% zinc.
2. An alloy composed of 40% Monel metal, 30% tin and 30% zine.
In testimony whereof we afiix our signatures.
