Definitions
- low torsion modulus alloys especially useful as tension bands for measuring instruments are composed essentially of platinum or palladium admixed with at least one element ofGroups 111. IV. V and VI of the Periodic Table excluding boron. carbon. nitrogen and oxygen.
- a taut strip or tension band must perform three functions: 4 i v 2. it providescurrent to "the measuring mechanism; and i i 3. it imparts the required resetting moment to the measuring mechanism.
- the requirements placed on the taut strip due to the simultaneous performance of these three functions are I very high and often exclude one another due to their opposite nature.
- the strip As a bearing, the strip must have the highest tensile strength without being brittle in order to be able to withstand shocks and vibrations. In the interest of high sensitivity, a small reset moment is required.
- materials for taut strips must have as high as possible a breaking strength factor 0",; on the one hand and as low as possible a modulus of torsion G.
- the suitability of a material for tensioning belts is thus characterized by a parameter or quality factor 2 which is equal to the breaking strength divided by the square root of the modulus of torsion of the respective material.
- the tension band material In addition to the breaking strength and torsion modulus, the tension band material must be corrosion resistant, workable and easily solderable. For the production of high precision measuring instruments it is additionally important that the elastic after-effect and hysteresis be as low as possible. In certain cases in which low or normal demands are placed on the breaking strength of the taut strip suspension, it is desirable to reduce at least the torsion modulus as much as possible.
- platinum/iridium alloys with an iridium content up to platinum/nickel alloys with a nickel content of 8 to 12.5% and gold/nickel alloys have been preferred for the taut strips.
- Alloys of the platinum metals (platinum, palladium, rhodium) with 5 to 40% iron, cobalt, nickel, tungsten, molybdenum, copper or silver and l to 30% iridium are suggested for fabrication of tension bands in German Pat. No. 1,152,826.
- the present invention relates to the use of an alloy consisting predominantly of palladium and/or platinum as the material for tensioning belts in measuring instruments having a rotatable measuring mechanism.
- the present invention is directed to the problem of providing alloys to be used as taut strip materials,
- ladium withl0to 14% by weight antimony, palladium and preferably 5 to 25'wcight "/1 tellurim or of palladium andlpreferably 5 to 20% gallium. have been found to be'particularly advantageous.
- Particularly low torsion moduli and highest quality factors can be obtained with alloys which contain, in addition to at least one 01 ement of Groups 111, IV, V and VI of the Periodic Table, gold, silver and/or copper. Examples of such alloys are palladium with 2 to 6% by weight aluminum and l to 307: by weight copper and/or silver and palladium with 5 to 20% by weight gallium and 1 to 60% by weight copper.
- Alloys having the composition of this invention have minimum torsion moduli in the order to 3000 and maximum quality factors of about 3.70 which are substantially more favorable than the values previously considered optimum.
- Examples 1 and 2 are alloys according to the present invention having a relatively low quality factor but the torsion moduli of these alloys lie substantially below the previously attainableflvalues which is to be desired.
- the other two-component alloys, Examples 34 have higher breaking strengths and higher quality factors than the alloys of Examples 1 and 2, with even lower values for torsion modulus for the alloys of Examples 4-6.
- Examples 7-l0 there is an even more significant improvement in the breaking tension and the quality factor, with the torsion modulus substantially lower than that of prior alloys for use in taut strips.
- the alloys of Examples 3 and 7-10 have a good soldering property and a low elastic after-effect.
- the measure for soldering property the wetting angle between a strip of the alloy and a drop of solder, using rosin as the fluxing agent, that angle is 67 for palladium/aluminum 96/4 (Example 3), for 76% palladium/47: aluminum/% silver the angle is 15 and for 8071 palladium/10% gallium/10% copper the angle is l0.
- the elastic after-effect for palladium/aluminum 96/4 is 0.02%, and for 80% palladium/10% gallium/l072 copper it is 0.05%.
- the after-effect behavior of the new alloys is thus at least as good as that of the previously used materials,
- one or more of the elements listed below can also be used, according to the present invention, as a component in these palladium and/or platinum alloys: germanium, silicon, bismuth, lead, tellurium, arsenic and selenium.
- alloys which possess a low tension modulus and other properties suitable for taut strips or tension bands are platinum with 2-3% tin, platinum with 1-3% aluminum or platinum with 525% cadmium.
- a low modulus of torsion, high quality factor taut strip for measuring instruments sai-d taut strip being formed of an alloy which consists essentially of 80 percent by weight palladium, 10 percent by weight gallium, and I0 percent by weight copper, and the quality factor Z of the taut strip is 3.73.
