High precision 4J36 Invar36 FeNi36 alloy coil strip
Expansion Alloy
Grade:4j29,4j36,4j42,4j43,4j44,4j47,4j50etc.
Sharp:wire, bar/rod, strip, sheet, tube
standard:GB/T15018,YB/T5231-2005,YB/T5241-2005,YB/T5235-2005etc.
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.
Expansion alloy applications: It is widely used in glass, metal and ceramic sealing in avionics and instruments, electric vacuum industry and other electronic devices, electric light source and other fields.
Invar36 has the following features:
extremely low coefficient of thermal expansion between -250℃ and +200℃
good plasticity and toughness
