Product Description

 

Product Description

Precision alloy Invar, also known as FeNi alloy, is an alloy with extremely low coefficient of thermal expansion. It is mainly composed of iron (Fe) and nickel (Ni), usually containing 36% nickel and 64% iron. This alloy is known for its extremely small coefficient of linear expansion under temperature changes, which means it has a very stable size over a wide temperature range.
The low thermal expansion of Invar alloy makes it widely used in applications that require high precision and stability. It is often used to manufacture precision instruments, astronomical telescopes, laser equipment, clocks, aerospace components, and precision instruments in scientific laboratories. Due to its unique performance, Invar alloys play a crucial role in many fields that require high stability and reliability.

Kovar alloy is a vacuum melted, iron-nickel-cobalt, low expansion alloy whose chemical composition is controlled within narrow limits to assure precise uniform thermal expansion properties. Extensive quality controls are employed in the manufacture of this alloy to ensure uniform physical and mechanical properties for ease in deep drawing, stamping and machining.

Kovar alloy has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials.
This alloy has found wide application in power tubes, microwave tubes, transistors and diodes. In intergrated circuits, it has been used for the flat pack and the dual-in-line package.

Thermal Expansion Properties

The following are the average coefficient of expansion properties after annealing in hydrogen for 1 hr at 1650°F (900°C) and 15 minutes at 2010°F (1099°C) and cooled to room temperature within 1 hr. Material heat treated using this procedure should not exhibit any transformation when cooled to -112°F (-80°C) for 4 hrs. This was determined by means of metallographic examination.

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
Precision 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.6J10,6J15,6J20,6J22,6J23,6J24
