Basic performance: It is divided into low-expansion alloy and fixed-expansion alloy, the latter is also known as sealing alloy.
Expansion alloy besides has the specific thermal expansion coefficient, according to the different USES also requires a good sealing property, weldability and corrosion resistance, machinability and cutting, and in the use of expansion characteristics caused by the temperature range there is no obvious change of phase transformation, its product is commonly bar, sheet, strip, wire and tube and so on.
