“…In the past few years, there have been reports of low-melting-point filler metals for brazing aluminum alloys developed by adding copper into Al-Si alloys [6,7]. Tsao et al [8] used Al-9.6Si-20Cu filler metal to braze 3003 aluminum alloy at 550 • C and obtained a bonding strength of 77 ± 14 MPa. This study employs two Al-Si-Cu filler metals to join 6061 aluminum alloy.…”

“…The direct and indirect effects of rare earth elements on heat resistance, formability and shear strength of final products have been studied as well [20]. Moreover, addition of copper and nickel to the conventionally used Al-Si filler metals can decrease the melting point of the filler metal and can be considered as another extensive research field in this context [18,21,22]. It should be noted that development of low melting point filler metals by different approaches have been the purpose of many other related investigations regarding vacuum brazing of Al alloys [23].…”

In this study, vacuum furnace brazing was used for joining AA3003 alloy with different thicknesses of 0.6 and 3 mm using BALSI-4 filler metal. Firstly, the samples were degreased using water and soap and then cleaned with acetone. The set-up was assembled and pre-heated for two-steps at 235 and 339°C and subsequently, moved to furnace. Vacuum brazing was conducted at temperature range of 590 to 630°C for different holding times of 5 and 10 min followed by furnace cooling. After primary visual checking, three samples for each thickness were selected for evaluation of microstructure and mechanical properties. Results indicated that furnace temperature and holding time significantly influenced microstructural evolution and mechanical properties. This effect was attributed to the distribution of Si and its relevant eutectic and pro-eutectic phases. It was deduced that the amount and distribution of such phases together with joint assembling design controlled the mechanical and fracture behavior. Furthermore, it was found that the quantitative amounts of pro-eutectic Si and Al-Si eutectic phases significantly increased the hardness of the joint. Therefore, the joint brazed at 610°C and dwelling time of 10 min was identified to offer the optimal mechanical properties.

“…The automotive industry always demands high reliability of its auto components to meet safety requirements. Various joints in automotive body parts, such as rooftops, hood, and car door frame are important parts requiring high reliability [1][2][3][4][5][6]. For joining steel sheets, fusion welding, friction, spot and laser welding have been used [7,8].…”

Arc brazing of zinc-coated steel (EG, Electro-galvanized steel) using Cu-3 wt%Si filler metal was performed. The influence of arc current and brazing speed on the bonding properties of the joint, such as bead characteristics, arc penetration, joint hardness, and tensile shear strength were evaluated. The microstructural characteristics of the joint were examined by scanning electron microscopy (SEM) and the compositional information was revealed by energy dispersive spectroscopy (EDS). The throat thickness varies inversely with the brazing speed. The EG joint shows the formation of Fe2Si phases, which result in higher microhardness than the base metal. The tensile samples were fractured in base metal, while minor bead cracks developed in the samples brazed at 80 cm/min-80 A, 60 cm/min-70 A, 70 cm/min-70 A.
