Kovar Alloy

Kovar alloy, ASTM F15, Nilo-K,UNS K94610(FeNi29Co17),Chinese 4J29
Kovar Alloy, is a controlled expansion alloy. It is a Nickel Iron alloy with 29% Nickel, 17% Cobalt and the remaining balance is Iron.
Forms: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube

Invar Alloy

Invar alloy,ASTM F1684,UNS k93600(FeNi36),Chinese 4J36
A Nickel-Iron, low expansion alloy containing 36% Nickel. It maintains nearly constant dimensions over the range of normal atmospheric temperatures.
Forms: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube

Hiperco 50A

Hiperco 50A is an alloy of 49% Cobalt,and 2%Vanadium, balance Iron,Hiperco 50A have the highest magnetic saturation of all soft-magnetic alloys and excels in applications where this attribute is needed.
Forms: Sheet/Plate, Bar/Rod/Coil

HiperCo 27

HiperCo27 alloy is an iron-cobalt-chromium soft magnetic alloy possessing the highest degree of ductility and toughness in the commercially available iron-cobalt grades of high saturation and high Curie temperature soft magnetic alloys. Although the permeability and coercive force of HiperCo 50 alloy are somewhat better than HiperCo 27 alloy, the magnetic saturation of both alloys is nearly identical. In addition, HiperCo 27 alloy does not exhibit the brittleness of HiperCo 50 alloy.
Forms: Sheet/Plate, Bar/Rod/Coil

Super Invar

Super Invar ,A low expansion alloy consisting of 32% Nickel, 4% Cobalt, and balance Iron. Super Invar Alloy exhibits minimum thermal expansion at room temperatures (one half of Invar Alloy), as well as thermal expansion properties less than that of Invar Alloy in the 67/203°F (-55/95°C) temperature range.
Forms: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube

Ceramvar Alloy

Ceramvar alloy, ASTM F1466,(Ni27Co25),Chinese 4J33/4J34
CERAMVAR ALLOY or we call iron-nickel-cobalt alloys, nominally 27% nickel, 25% cobalt and 48% iron, in the forms of wire, rod, bar, strip, sheet, and tubing, intended primarily for brazed metal-to-ceramic seals with alumina ceramics, for vacuum electronic applications. Unless otherwise indicated.
Forms: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube

70HB

Non-magnetic constant expansion ceramic-sealing alloy. 70HB applies to gyroscope and vacuum electronic devices in the non-magnetic ceramic sealing material.

Alloy 42

Alloy 42,ASTM F30,UNS k94100,(Fe-42Ni) ,Chinese 4J42
42 Alloy, a low expansion alloy, is very similar to Invar 36 with a slightly different Coefficient of Thermal Expansion. This nickel-iron alloy is ideal forlid, lead frames, stencil/etching, telecommunications and aircraft industry, offering a more affordable alternative to Kovar when a tight seal is not required.
Forms: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube

Alloy 79

Alloy 79 is a soft magnetic alloy consisting of 80% Nickel, 5% Molybdenum, and balance Iron used where extremely high initial & maximum permeability and minimum hysteresis is needed.
Forms: Sheet/Plate, Bar/Rod/Coil

65-Permalloy

65-Permalloy has a hysteresis loop and high saturation induction intensity. 65-Permalloy working in a secondary magnetic field of magnetic amplifier,chock coil,and computer components,etc.
Forms: Sheet/Plate,Wire,Bar/Rod/Coil
