铁基自熔性合金是铁——碳合金中加入一定量的硼、硅元素制成的，通常应用在常温——500℃以下耐磨损、耐弱酸腐蚀介质的机械零部件上，仅管铁基自熔性合金，综合性能不如镍、钴基合金，然而原料来源广泛，价格便宜，这是其得以普及应用的较大优势。下面介绍我公司铁基焊粉，建议用户在使用前应在120℃保温两小时低温烘烤后使用。
Iron-base fluxed alloy is produced by adding suitable amount of boron and silicon into iron-carbon alloy, which is usually used on the wearable and weak-acid-medium proofing accessories under 500℃. Although the performance of iron-base fluxed alloy can not match with that of the nickel or cobalt alloy, it has wide source materials and low prices, which is the great advantage for application. The following iron-base sprayed welding alloy powder should be dried by the customer under 120℃ for two hours before useing.
