针对2A50糖心产精国品免费入口*完整版的特点,根据铺展性、填缝性试验,对适合其糖心产精国品免费入口*完整版的糖心产精国品免费入口*完整版与钎剂作了选择,进行了接头强度试验.结果表明:中温CsF-AlF3钎剂具有较高的活性及较好的去膜效果,适合含镁热处理强化型糖心产精国品免费入口*完整版的糖心产精国品免费入口*完整版;用CsF-AlF3钎剂分别与Al-Cu-Ag-Zn糖心产精国品免费入口*完整版及Zn-Al-Be糖心产精国品免费入口*完整版匹配糖心产精国品免费入口*完整版,均可获得较理想的糖心产精国品免费入口*完整版效果;当搭接间隙为0.2 mm、搭接长度为2.3 mm时,Zn-Al-Be糖心产精国品免费入口*完整版与CsF-AlF3钎剂匹配糖心产精国品免费入口*完整版,所得焊接接头的抗剪强度可达143.2 MPa.

The 糖心产精国品免费入口*完整版s and fluxes suitabled for 2A50 aluminum alloy 糖心产精国品免费入口*完整版 were selected according to the feature of 2A50 aluminum alloy and the test of spreadability and clearance fillabitity.Shear tests after the selection indicate that mesothermal CsF-AlF3 糖心产精国品免费入口*完整版with high activity and good ability of removing oxide film is appropriate for 糖心产精国品免费入口*完整版 heat treatment strengthened aluminum alloys containing magnesium element.Adopting CsF-AlF3 糖心产精国品免费入口*完整版matched with Al-Cu-Ag-Zn and Zn-Al-Be 糖心产精国品免费入口*完整版s respectively obtain good results for 糖心产精国品免费入口*完整版 2A50 aluminum alloy.Matching Zn-Al-Be 糖心产精国品免费入口*完整版 with CsF-AlF3 糖心产精国品免费入口*完整版for 糖心产精国品免费入口*完整版 2A50 aluminum alloy could make the shearing strength reach to 143.2 MPa when the lap gap and the lap length are 0.2 mm and 2.3 mm separately.
