鐵基自熔性合金是鐵——碳合金中加入一定量的硼、硅元素制成的,通常應用在常溫——500℃以下耐磨損、耐弱酸腐蝕介質的機械零部件上,僅管鐵基自熔性合金,綜合性能不如鎳、鈷基合金,然而原料來源廣泛,價格便宜,這是其得以普及應用的較大優勢。下面介紹我公司鐵基焊粉,建議用戶在使用前應在120℃保溫兩小時低溫烘烤后使用。
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.
