噴焊合金粉末，通稱自熔性合金，亦稱硬面合金。鎳基噴焊合金粉末主要包括Ni－Cr－B－Si系列；Ni－Cr－B－Si－C系列；Ni－Cr－B－Si－C－Mo－Cu系列等,它具有優(yōu)良的綜合性能,耐腐蝕、抗氧化、耐熱耐低應力磨粒磨損和粘著磨損等，具有優(yōu)異的噴焊工藝性。
　　下而介紹我公司生產的鎳基噴焊合金粉末均采用塑料桶和鐵桶封裝但由于粉末粒度細，易于吸潮，建議用戶在使用前采用120℃保溫兩小時低溫烘烤后使用。
　　Sprayed welding alloy powder is generally called as fluxed alloy or hard surface alloy. Nickel-base sprayed welding alloy powder mainly include Ni－Cr－B－Si serial products；Ni－Cr－B－Si－C serial products；Ni－Cr－B－Si－C－Mo－Cu serial products.The products have integrated performances. They are antirust, anti-oxidation, heat-resistant, with low stress abrasive particle wear resistance or adhesive wear resistance and has excellent technical performance for sprayed welding. 　　
　　The following nikel-base sprayed welding alloy powder produced by our company is packaged and sealed in the plastic or metal pail. However, for the thin granularity and humidity-absorbing characteristic of the product, we suggest that the customer dry the products under 120℃ for two hours before use.
