研究了添加助烧剂对铝、Al-Si-Cu-Mg-Fe合金和铝青铜烧结的影响。添加AlF3-KF对铝烧结是有效的，但对Al-Si-Cu-Mg-Fe合金无效。认为Al-Si-Cu-Mg-Fe合金通过与铝助烧剂的共晶反应去除了粉末表面的氧化物，但KF和Mg反应生成的高熔点的MgF2阻碍了Al-Si-Cu-Mg-Fe合金的烧结。虽然单独添加AlF3是一种有效的烧结助剂，但添加AlF3-KF可以降低铝青铜的烧结温度。
Effects of addition of sintering aids on sintering of aluminum, Al-Si-Cu-Mg-Fe alloy and aluminum bronze were investigated. The addition of AlF3-KF is effective in case of aluminum sintering but not effective in case of Al-Si-Cu-Mg-Fe alloy. It is considered that the surface oxide of the powder is removed by the eutectic reaction with the sintering aids for aluminum, but that the formation of high melting MgF2, which is the reaction product of KF and Mg, prevents the sintering of Al-Si-Cu-Mg-Fe alloy. The addition of AlF3-KF was found to reduce the sintering temperature for aluminum bronze although AlF3 alone is an effective sintering aid.
