As shown in FIG.1,an air-tightly sealed container 1 was formed at all of the container side wall 2,the cylindrical portion 3 and the bottom plate 7 out of covar,i.e.,an alloy of Fe--Ni--Co (the thermal expansion coefficient of which was 5.0×10-6 /°C.),and a covar pin was sealed as a terminal to the container 1 with glass of a low Batteries fifty years of materials development Oct 01,2000·After lead/acid,nickel/cadmium is the most widely used rechargeable battery.The cell operating voltage (1.20 V) is slightly less than that of Ni/Fe (1.25 V) and the mass of cadmium is higher than that of iron.Taken together,these two factors lead to a specific energy for the battery (3040 Wh/kg) which is nearer to that of lead/acid than

Monel is another nickel alloy made of mostly nickel and steel with small amounts of iron,manganese,silicon,and carbon.The alloy is stronger than steel and malleable.It is relatively inexpensive and resistant to corrosion.Similar to some of the other alloys listed here it has aMicrowave-cavity measurements for gas thermometry up to May 13,2013·For welding,we used another NiFeCr alloy available in rod form Haynes 556.The outer conductors of the coaxial cables were tubes (3.2 mm OD; 2.2 mm ID) of the NiCrFe alloy 'Inconel-625' (Special Metals Corp.,Huntington,WV,USA).The same tubing stock was used to make the ducts that delivered the argon to the test cavities.NEW PATENTS July 1966 Johnson Matthey Technologythe international nickel inc.U.S.Patent 3,217,404 Components made of Pt or its alloys with up to 40% Ir,up to 5% Os,up to 50% Pd,up to 40% Rh or up to 15% Ru are united so that the finished structure may be used at up to 1450°C or even higher temperatures,by placing between the parts a brazing alloy comprising 0100% Au and 0100% Cu,maintaining the assembly for 0.5150 min
