產(chǎn)品詳情
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(yīng)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(chǎn)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 perbances. They are antirust, anti-oxidation, heat-resistant, with low stress abrasive particle wear resistance or adhesive wear resistance and has excellent technical perbance for sprayed welding.
The following nikel-base sprayed welding alloy powder produced by our company is packaged and sealed in the plastic or bl pail. However, for the thin granularity and humidity-absorbing characteristic of the product, wesuggest that the customer dry the products under 120℃ for two hours before use.
