style="text-indent:25px">電機(jī)中常用的磁鐵材質(zhì)有哪些:鋁鎳鈷：鋁鎳鈷永磁材料是較早普遍使用的一種永磁材料，其制備工藝和技術(shù)比較成熟。目前日本、美國、歐洲、俄羅斯、中國都有工廠生產(chǎn)。在大規(guī)模的生產(chǎn)企業(yè)當(dāng)中，杭州永磁的產(chǎn)量目前在國內(nèi)數(shù)很好，年產(chǎn)能力達(dá)3000噸。永磁鐵氧體材料：進(jìn)入50年代，鐵氧體開始蓬勃發(fā)展起來，尤其是70年代，在矯頑力、磁能機(jī)方面性能較好的鍶鐵氧體大量投入生產(chǎn)，迅速擴(kuò)大了永磁鐵氧體的用途。作為一款非金屬磁性材料，鐵氧體沒有金屬永磁材料易氧化、居里溫度低、成本高的弊端，因此大受歡迎。釤鈷材料：20世紀(jì) 60年代中期興起的磁性能優(yōu)異的永磁材料，且性能非常穩(wěn)定。釤鈷從磁性能方面來說特別適合于制造電機(jī)，但由于其價格昂貴，主要用于研究開發(fā)航空、航天、武器等電機(jī)和高性能而價格不是主要因素的高科技領(lǐng)域的電機(jī)中。整個轉(zhuǎn)子鐵芯高度 140mm 以上，還不適合用注塑工藝。貴州工業(yè)設(shè)備磁鋼批發(fā)</p><p
