And properties of industrial aluminum alloy solder

0 Series and 6000 series alloy welding,[link widoczny dla zalogowanych], in particular chemical composition: Si <0.20, Fe <0.30, Cu crack the case, with the A4047 solder most appropriate. 0.25, Ti0.10 ~ 0.20, the other total <0.15, AI quasi-component AI-Mg-Mn alloys, for Mg content of cushion. General AI - Cu alloy solder welding is easy to produce low-Al-Mg alloys (5052,5454, etc.), corrosion resistance, then the crack, resulting in poor welding. In the A1 - Cu alloys in the process of adding the fine, can be used as a structural material, and can be used with the temperature more than 55c of the chemical plant welding. ( Cool

A5654 - BY (WY) chemical composition: si + Te <O. 45, Cu <O. 05, Mn <0.01, Mg3.1 ~ 3.9, Cr0.15 ~ 0.35, Zn <0.25, Ti0. O5 ~ O. 20, Other Total <o. 15, Al margin. The solder is the strength of Al-Mg alloy welding the corresponding solder, apply hydrogen peroxide with a 5254 alloy device can also replace the abolished 5154 - BY (wY) solder alloy used for welding base material 5154. As versatile as 5356 solder, the use of narrow, small dosage. Joint strength was 205 ~ 265N/ram. (9) A5356 A BY (WY) chemical composition: si <0.25, Fe <0.40, Cu <0.10%, Mn0. O5 ~ 0.2O, Mg4.5 ~ 5.5, Cr0.05 ~ 0.20, Zn <0.10, Ti0.06 ~ 0.20, the other total <0.15, Al margin. The solder used in an Al-Mg (Mn) is non-alloy and heat treatment Al-Mg-Si system and 7N01 alloy materials such as heat welding. Add a small amount of Mn, Cr, Ti, etc. in order to refine grain and improve the mechanical properties of weld metal. The grade solder welding, good applicability, the use of a wide range of solder alloy used for all accounts for 50 to 60. Welding base metal 5083--0, the joint strength was 265 ~ 305N/ram. (10) A5556 A BY (WY) to 5.1Mn as a standard component of AI-Mn alloy, the mechanical properties of weld metal excellent joint strength slightly higher than the 5356 alloy, to reach 275 ~ 315N/mm. (11) A5183 A BY (WY) to 4.8Mg, 0.75Mn as a standard component of the Al-Mg-Mn alloy, added trace elements have sj <0.40, Fe <0.40, Cu <O10, Cr0 . O5 ~ 0.25, Zn <O. 25, Ti <0.15. A5183 Solder 5083 is best suited for welding base metal, corrosion resistance, excellent mechanical properties, and a welding Al-Mg (Mn) alloy and 7N01 alloys, good ductility and toughness when welding 5083 base metal, joint strength achieved. 275 ~ 305N/mm. Zhu Jianguo translated where no soldering components after welding need to remove the excess solder pure, fee I time-consuming and not suitable for automatic soldering 'Art. In addition, diffusion area too, at 4. o ~ 6. gmm, bonding strength is low, 750 ~ -. 78Okg, and the offensive side in particular, instability in Kaiping Japanese patent 7-88683 special problems for the After j study found that the main problem is a combined solders have high levels of s, in 150 ~ 200ppm, by controlling impurities in solders s containing the amount of material to provide a brazing a small area and spread evenly dispersed stone roller copper solder. New Brazing Cu, Ag and P content of the phosphor with the previous brazing the same, but the station has impurities s volume will be less frequent in the lOOppm, if more than 100ppm, with the proposal to soldering, as solder spread area too, and uneven. New high melting point solder 5O degrees than the temperature of the soldering, solder spread area is small (1.O ~ 2.0mm.) And even, and joint strength (800 ~ 830kg), partial dirty small, good stability . The composition of the new solder 8O ~ 87Cu, 6 ~ 15Ag, 5 ~ 7P, s5 ~ 5oppm, for brazing copper, copper alloy, Hu, molybdenum and other components, suitable for automatic soldering 'Art. Ben Kanxun 21
