在这里,我们将解释钕磁铁的型号差异。一切都以字母”N”开头,所有钕磁铁的名称都以“N”开头,表示钕。后面的数字更具技术性,因为它代表了(MGOe)中磁铁的最大能量积。这是磁铁‘强度”的主要指标。简而言之，最大能积值越高,磁铁在特定应用中产生的磁场就越大。
通常可以购买的等级范围从N30到N52 ,因为通常不再生产较低等级的产品。我们的大部分磁铁都是N42或更高级别的,这使得它们的磁性比许多便宜的N35级钕磁铁高20%。N42 等级以经济的价格提供高性能。N42以上的等级往往更贵, 而且价格的上涨可能与性能的提高不成比例。一个例子是N52等级,它比N42等级强大20% , 但价格可能是其两倍。
在需要最高性能且磁体可用空间有限且无法增加的情况下,应使用更高等级的产品。否则使用两个N42磁铁而不是一个N52磁铁会更有利。有时,您可能还会看到一两个字母标记在末尾。这些字母决定了温度额定值并代表磁铁在开始永久失去磁性之前可以承受的最大:工作温度。这些额定值应始终被视为指导值,因为尺寸和形状等其他因素也会影响磁铁在高温下的性能。
