microwire made of nickel alloy covered with borosilicate glass, manufactured using the Taylor-Ulitkow method, wound on a spool, used as a passive sensor requiring further processing
Description auto translated : The product is a microwire made of nickel alloy, which is covered with borosilicate glass (pyrex glass/symax glass). The goods are manufactured using the Taylor-Ulitkow method of production (induction-melted metal is drawn in an unsoftened pyrex tube, where there is a vacuum and then it is rapidly cooled). The product is hot-drawn Microwire, wound on a spool. The goods have dimensions: the diameter of the metal core is 1-50 micrometers, the total diameter including the core is 3-70 micrometers, the glass insulating coating is 2-20 micrometers. The winding on the coil depends on the client's requirements, it can normally vary from 1 m to 10 km.
Chemical composition of the goods:
Ni(42-48%)Fe27(Ga15-21%)Cu(2-8%)
Ni(46-54%)Fe(16-23%)Ga(23-27%)Co(2-8%)
Ni(46-49%)Fe(28-31%)Ga(15-21%)Si(2-8%)
Ni(46-55%)Fe(18-29%)Ga(15-27%)
Winding on a coil is a method of distribution of goods Microwire made of nickel alloy covered with borosilicate glass. In order for the product to become a passive sensor, further processing is required, for example:
• cutting to the desired length
• heat treatment or mechanical treatment
• gluing/application to the surface.
After processing, the product is used as a separate, passive sensory element/sensor, on the basis of its chemical and physical properties, it reacts magnetically to changes in external quantities.
Original Description: Tovarom je Mikrodrôt zo zliatiny niklu, ktorý je obalený bóro-silikátovým sklom (pyrexové sklo/symaxové sklo). Tovar je vyrábaný metódou Taylor-Ulitkowská metóda výroby (indukčne roztavený kov sa ťahá v nemäknutej pyrexovej skúmavke, kde je vákuum a následne sa prudko chladí). Tovar je Mikrodrôt ťahaný za tepla, navinutý na cievke. Tovar má rozmery: priemer kovového jadra je 1-50 mikrometrov, celkový priemer vrátane jadra je 3-70 mikrometrov, sklený izolačný povlak je 2-20 mikrometrov. Návin na cievke závisí od požiadaviek klienta, bežne môže variovať od 1 m po 10 km.
Chemické zloženie tovaru:
Ni(42-48%)Fe27(Ga15-21%)Cu(2-8%)
Ni(46-54%)Fe(16-23%)Ga(23-27%)Co(2-8%)
Ni(46-49%)Fe(28-31%)Ga(15-21%)Si(2-8%)
Ni(46-55%)Fe(18-29%)Ga(15-27%)
Návin na cievke je spôsob distribúcie tovaru Mikrodrôt zo zliatiny niklu obaleného bóro-silikátovým sklom. Na to aby sa tovar stal pasívnym senzorom je potrebné ďalšie spracovanie, napríklad:
• strihanie na požadovanú dĺžku
• tepelná úprava alebo mechanická úprava
• lepenie/aplikácia na povrch.
Tovar sa po spracovaní používa ako samostatný, pasívny senzorický element/senzor, na základe svojich chemických a fyzikálnych vlastností reaguje magnetickým prejavom na zmeny externých veličín.
