Telecurso 2000 Materials: http://bmalbert.yolasite.com/resource... The last alloys in the copper family are those in which nickel is present in proportions ranging from 5 to 50%. These alloys have good ductility, good mechanical and oxidation resistance, and good thermal conductivity. They are easily formable, and can be transformed into sheets, strips, wires, tubes, and bars. They can be joined by most brazing methods and by tin soldering. With a proportion of up to 30% nickel, the alloy is used in hydraulic and pneumatic piping, coins and medals, and in the manufacture of resistors, capacitor components, heat exchanger tubes, bushings, saltwater conduits, distillers tubes, resistors, and capacitors. Alloys with nickel contents in the range of 35 to 57% are called constantan and are used in the manufacture of resistors and thermocouples. A thermocouple is a system that measures temperature differences. It consists of two wires of different metals with their ends welded together. When they are at different temperatures, a potential difference, or voltage, arises between the two. The voltage scale corresponds to a temperature scale, and thus it is possible to obtain the desired temperature difference value.
