鐵硅鋁磁環(huán)的切割加工

鐵硅鋁磁環(huán)是一塊環(huán)狀的導磁體，是使用率較高的磁環(huán)之一，簡單來說，鐵硅鋁是由鋁-硅-鐵組成，在國際上鐵硅鋁磁環(huán)可稱之為磁粉芯。它的磁芯損耗遠低于鐵粉芯及高磁通，是低成本的儲能材料，無熱老化，可以用于替代鐵粉芯，在高溫下性能非常穩(wěn)定，鐵硅鋁的標準色為黑色。

鐵硅鋁磁粉芯具有的磁磁性能，功率損耗小，磁通密度高，在-55C~+125C溫度范圍內使用時，具有耐溫、耐濕、抗振等高可靠性，同時擁有較好的軟飽和度、可忽略不計的磁芯損耗、溫度的穩(wěn)定性；

鐵硅鋁磁環(huán)電感，主要是有扼流的作用，同時還有儲能的作用，是開關電源輸出扼流圈、PFC電感及諧振電感的佳選擇，具有較高的性價比；在精度方面，鐵硅鋁磁環(huán)電感的精度一般是20%左右，它的線徑比較粗，電流很大。

由于制作鐵硅鋁磁環(huán)時，在純鐵中加入了硅和鋁高含量材料，使材料的磁滯伸縮系數(shù)接近零，降低了材料將電磁能轉化為機械能的能力。

鐵硅鋁磁環(huán)是開關電源之需，是其他磁性材料無法替代的產(chǎn)品，在開關電源方面它可以發(fā)揮出顛峰的效果，如使用錳鋅/鎳鋅磁環(huán)在電源上，幾乎起不了作用，這就是鐵硅鋁磁環(huán)特的一面。鐵硅鋁磁環(huán)包含了85%鐵、9%硅和5%鋁合金粉料，用這幾種材料制成鐵硅鋁磁環(huán)，可以大大提高它飽和磁感應強度、直流疊加特性。

除此之外，鐵硅鋁磁環(huán)已廣泛應用于計算機主機板，計算機電源，電源供應器，手機充電器，燈飾變壓調光器，不間斷電源（UPS），各種家用電器控制板等。

在生產(chǎn)電感器時，部分的圓形電感器需先將磁感線纏繞好，再將磁環(huán)切割成兩段，將繞好的磁感線套在磁環(huán)上后再將兩段的磁環(huán)粘合。該步驟加工的精度要求較高，傳統(tǒng)的切割工裝在切割磁環(huán)時，因對磁環(huán)施加向下的壓力容易導致磁環(huán)左右兩端不平衡，從而磁環(huán)的軸線發(fā)生偏移，導致切割誤差。推薦使用億博智能的金剛砂線切割機進行切割加工。
