FeNi42 Yumu\u015fak Manyetik Toz Nedir ve Malzeme Avantajlar\u0131 Nelerdir?<\/h2>\n\n\n\n

FeNi42 yumu\u015fak manyetik toz<\/strong> Yumu\u015fak manyetik ve kontroll\u00fc genle\u015fmeli ala\u015f\u0131mlardan olu\u015fan demir-nikel ailesine aittir; bu gruba FeNi50 ve 78-80% nikel civar\u0131ndaki y\u00fcksek ge\u00e7irgenlikli permalloy kaliteleri de dahildir. Tan\u0131mlamadaki \u201c42\u201d rakam\u0131, a\u011f\u0131rl\u0131k\u00e7a y\u00fczde 42 olan nominal nikel i\u00e7eri\u011fini ifade eder; geri kalan k\u0131sm\u0131n neredeyse tamam\u0131 demirden olu\u015fur. D\u00f6vme formunda bu bile\u015fim, uluslararas\u0131 standartlara g\u00f6re Alloy 42, UNS K94100, DIN 1.3917 ve Nilo 42 gibi ticari isimler alt\u0131nda uluslararas\u0131 standartlara uygun hale getirilmi\u015ftir ve on y\u0131llard\u0131r cam-metal contalar, seramik paket kur\u015fun \u00e7er\u00e7eveleri ve yar\u0131 iletken hermetik muhafazalar i\u00e7in varsay\u0131lan malzeme olarak kullan\u0131lmaktad\u0131r.<\/p>\n\n\n\n

Daha geni\u015f kapsamda yumu\u015fak manyeti\u0307k tozlar<\/a> Katmanl\u0131 \u00fcretim ve toz metalurjisi i\u00e7in kullan\u0131labilen FeNi42, kendine \u00f6zg\u00fc bir orta konumda yer almaktad\u0131r. FeNi50 ve permalloy gibi nikel i\u00e7eri\u011fi daha y\u00fcksek olan ala\u015f\u0131mlar, daha y\u00fcksek maksimum ge\u00e7irgenlik ve daha d\u00fc\u015f\u00fck koersif kuvvet sa\u011flar; ancak nikel i\u00e7eri\u011fi artt\u0131k\u00e7a termal genle\u015fmeleri artar ve doygunluk ak\u0131 yo\u011funluklar\u0131 d\u00fc\u015fer. FeNi42, manyetik performans\u0131ndan bir miktar \u00f6d\u00fcn vererek iki belirleyici avantaj elde eder: yakla\u015f\u0131k 1,4-1,5 T'lik bir doygunluk ak\u0131 yo\u011funlu\u011fu, ki bu de\u011fer y\u00fcksek nikel i\u00e7erikli permalloylar\u0131nkini a\u015far; ve yakla\u015f\u0131k 400 \u00b0C\u2019ye kadar al\u00fcmina seramikleri ve s\u0131zd\u0131rmazl\u0131k camlar\u0131yla yak\u0131ndan e\u015fle\u015fen, neredeyse sabit ve d\u00fc\u015f\u00fck bir termal genle\u015fme katsay\u0131s\u0131.<\/p>\n\n\n\n
