, 4j50 Nickel Alloy Strip/Coil/FoilProduct DescriptionPrecision
alloys are metal materials with special physical properties (such
as magnetic, electrical, thermal and other properties). The vast
majority of precision alloys are based on ferrous metals, and only
a few are based on non-ferrous metals. Usually include magnetic
alloys (see magnetic materials), elastic alloys, expansion alloys,
thermal bimetals, electrical alloys, hydrogen storage alloys (see
hydrogen storage materials), shape memory alloys, magnetostrictive
alloys (see magnetostrictive materials), etc. Chemical

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.1J06,1J12,1J17,1J18,1J22,1J30,1J36,1J38,1J46,1J50,1J51,1J54,1J76,1J77,1J79,1J80,1J85,1J87Permanent
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.4J28,4J29,4J32,4J33,4J36,4J40,4J42,4J50Precision alloys with
nickel, chromium, aluminum and iron as the main components, the
resistivity is about three times higher than that of manganese
copper, and has a lower temperature coefficient of resistance and
low thermal potential to copper, with good long-term resistance
stability and resistance. Oxidation properties.It is suitable for
making precision resistance elements in various measuring
instruments and meters, making precision micro-resistance elements
and strain gauges.6J10,6J15,6J20,6J22,6J23,6J24Expansion
