60 % Copper 40 % Nickel Convection The heat is transfered from the solid or liquid by the surrounding gas. If the flow of gas away from the object starts by itself it is called natural convection. However, if the gas is forced past the object it is called forced convection. Note: convection may also occur within a fluid carrying heat away from a solid. See also: Heat.
An alloy of 40% nickel and 60% copper. Used with copper in T-type thermocouples.
A generic designation for a thermocouple alloy made of 55 percent copper and 45 percent nickel that is used as the negative conductor in ANSI Type E, J, and T thermocouples.
A copper-nickel alloy used as the negative lead in Type E, Type J, and Type T thermocouples.
The negative leg of types E, J and T thermocouples. Constantan is 55% copper and 45% nickel. The emf values can be significantly different for this material depending upon with which type of thermocouple alloy it is intended to be matched.
Constantan is an alloy usually consisting of 55% of copper and 45% of nickel (Cu55Ni45). Its main feature is its resistance which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients are known, such as manganin (Cu86Mn12Ni2).
