Product Description

ASTM F15 4j29 Feni29co17 Kovar Expansion Precision Alloy Round Bar

ASTM F15 4j29 Feni29co17 Kovar Expansion Precision Alloy Round Bar Ni29Co18/ UNS K94610 (4J29) Kovar Expansion Precision Alloy Strip Price

Precision alloy 4J29 is a Fe-Ni-Co alloy, and it has similar liner expansion coefficient with hard borosilicate glass under the temperature of 20-450ºC, with high Curie point and good low-temperature stability.4J29 has tense oxide film and can be well wetted by the glass. It is suitable for mercury discharge instrument because it doesn't react with mercury. 4J29 alloy is the main material of sealing parts in electric vacuum devices.

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.
