Abstract

The effect of 0.5 wt-% SiC nanoparticle addition on microstructure and brazeability of Al-9Si-20Cu alloys has been investigated. The brazing is performed using the filler at 550˚C for 30 min. Microstructural observations reveal the refinement of Si and CuAl₂ in Al-9Si-20Cu-0.5SiC composite. The average size of Si particles decreases from̴ ∽, 9 to, ∽4 mm. It has been shown that SiC nanoparticles improve the filler brazeability; the spreading ratio increases up to 88.4% as compared to 76.67% over Al-9Si-20Cu alloy. The tensile strength and ductility of Al-9Si-20Cu-0.5SiC are also enhanced by 47 and 53% respectively. The melting point shows a depression, ∽ 4˚C in Al-9Si-20Cu-0.5SiC and thus can be a potential filler candidate for brazing industries.
