Analysis of Mechanical and Metallographic Properties on The Joining Between Aluminum and Brass by Using The Brazing Method

Abstract

The objectives of this research is to investigate the tensile strength and structure of metallography of the metal connection between aluminum and brass by the brazing method. The type of joining is the but joint using an alusol filler. Specimens were made according to ASME IX standards. The ASTM E8 standard was used to tensile test. The macro and micro photos was carried out using ASTM E407-07. A joint with a shear area of 350 mm2 was broken when pulled with a load of 4.410 kN. The highest stress, strain and Young modulus was 12.601 N/mm2, 0.11 and 1.183 kN/mm2 respectively. The porous microstructure was seen in the weld area facing to the brass material. The chemical composition of the specimens consisted of C 21.53%, Al2O3 37.20%, CuO 13.63%, and ZnO 27.64% from the EDX results.
