Deskripsi Produk

 

Product Description

Precision nickel alloy 42 4j42 42K invar 42 foil strip tape lead frame expansion Feni glass sealing 
 

• UNS K94100, W.Nr. 1.3917
• ASTM F 29 (Wire)
• ASTM F 30 (Sheet, strip, rod, bar, tubing and wire)
• DIN 17745, AFNOR NF A54-301 (Composition)

Alloy 42 is a 41% nickel-iron controlled expansion alloy which has been used in a wide variety of glass-to-metal sealing applications.
While the expansion properties of this alloy most closely match 1075 glass, it has also been used in seals for the 0120 and 0010 glasses. It may also be used with hard glasses if a thin edged tubular seal is used. For seals that are not hydrogen annealed prior to sealing, a variation of this alloy containing small additions fo titanium, Glass Sealing 42 Gas-Free, has been used to promote gas-free sealing characteristics.

Applications

Alloy 42 has been used for the glass-to-metal seals in electronic tubes, automotive and industrial lamps, transformer and capacitor bushings and other glass-to-metal and ceramic-to-metal applications.

Product Parameters

Soft magnetic alloys are a class of alloys with high permeability and low coercivity in weak magnetic fields. According to the different elements that make up the alloy, it can be divided into electromagnetic pure iron (industrial pure iron), iron-silicon alloy, iron-nickel alloy, iron-aluminum alloy, iron-silicon-aluminum alloy and iron-cobalt alloy, etc.1J06,1J12,1J17,1J18,1J22,1J30,1J36,1J38,1J46,1J50,1J51,1J54,1J76,1J77,1J79,1J80,1J85,1J87

Permanent magnet alloy not only has high hardness and mechanical properties, but also has strong anti-demagnetization ability, high coercivity value (greater than 20kA/m), magnetic "hard" and other characteristics, so it is also called hard magnetic alloy.2J04,2J07,2J09,2J10,2J31,2J53,2J84,2J85Elastic alloys include high elastic alloys and constant elastic alloys. It is used to make elastic elements such as elastic sensitive elements, energy storage elements and frequency elements in precision instruments.3J01,3J21,3J53Expansion alloys(Invar Alloy) are divided into Kovar alloys, ceramic sealing alloys, low expansion alloys, and constant expansion alloys. Widely used in electronic industry, precision measuring tools, precision instruments and low temperature engineering and other fields.4J28,4J29,4J32,4J33,4J36,4J40,4J42,4J50
