Longevity-inc sells short term welders
Dec 2008 , paid $650 for Model 518 , broke quick cant figure how to fix it . Simon K sent 20 ingenuine emails , "Offering" a solution . So why cant i weld yet ? !! This aluminum tutor , is best ive eve seen , it gives the critical info needed to work with aluminum . from www.precisionsheetmetal.com .. 1) NON--heat-treatable (alloyed with manganese, silicon, iron, and magnesium) 1100=pure , 5052(magnesium) , 3003 , 2) heat-treatable (alloyed with copper, magnesium, zinc, and silicon). 2024-T3 = copper , 6061-T6 = ? 5052-H32 (QQ-A-250/8d) magnesium alloyed into 5052 helps corrosion . alloy is magnesium. Far stronger than any of the alloys described above, yet forms well with reasonable inside bend radii. Corrosion resistan weldable very good. Better salt water corrosion resistance than 1100. Used for electronic chassis, tanks, pressure vessels and any number of parts requiring considerable strength and formability at reasonable cost. Anodizing may be slightly yellowish. 1100-H14 (QQ-A-250/1d) Commercially pure aluminum, highly resistant to chemical attack and weathering. Excellent for chemical processing equipment and other uses where product purity is important. Easily worked and welded, ductile enough for deep draws, but the lowest strength aluminum alloy. Uses include light reflectors, decorative and jewelry parts, name plates. Seldom used in precision sheet metal -- see 5052-H32. 3003-H14 (QQ-A-250/2c) manganese alloy. Stronger than 1100 with same good formability and low cost. Fine corrosion resistance and weldability. Used in stampings, spun and drawn parts, mail boxes, cabinets, tanks, fan blades. For higher strength, consider 5052-H32. 6061-T6 (QQ-A-250/11d) Alloyed with magnesium & silicon. Heat treatable to improve strength. A widely used structural alloy . Requires much larger inside bend radii than 5052-H32. good weldability, corrosion resistant, and strength after heat treatment. looses strength when welded. 5000 series alloys replace it in truck dump body and some marine applications. |
