Influence of Alloying Element on Performance of Copper Base Solders
The effect of adding zinc powder and manganese powder to boronic sand on brazing was studied using H68 and H62 as brass solders,dehydrated boronic sand as flux,resistance brazing welderas thermal source.The result shows that adding Zn powder and Mn powder the solders spreading properties improves,the shear strength of the brazing points increases.
