Mangano - manganic oxide for soft magnetic ferrites use 软磁铁氧体用四氧化三锰
2.
High clow manganic metal pellet , which are the newest products that our company researches and explots , are the pioneering of the same trade . the products , which can substitute for importing stainless steels , are the perfect ones of precised foundry clearing the aluminum alloy surface sping affrandizement sping gear aggrandizement produce 高、低猛合金丸，使我公司最新研制开发生产，居同行首创，独家生产，该产品可替代进口不锈钢丸，是紧密铸造及铝合金铸造表面清理，弹簧，齿轮强化理想产品。
