EN 573-3 Grade AW-1050A Aluminum Alloy – 99.5% Pure, Food‑Safe, Versatile Industrial Applications

Material EN AW-Al 99,5 is produced in large quantities for sheets, strips, plates, scraps, foils, for presswork components, rolled and pressed bars, for prematerial for heat exchanger as well as for wire and prewire for mechanical and welding application. It is used in limited quantities for prematerial for cans, caps and fasteners as well as for forged parts and prematerial. It is food-safe. The material is comparable to trademark Al 99,5, material number 3.0255, acc. to DIN 1712-3 : 1976-12. It is well anodizable and shows favorable electrical and thermal conductivity. Smearing may occur on machining. Low mechanical strength, high strain. Formability as well as chemical and weathering resistance are excellent. This material is well suitable for welding and hard soldering. Application: apparatus engineering, roll bond, Z-bond, household appliances, storage and transport equipment for chemical, pharmaceutical and food industry, roofings, facings, arts-and-crafts, packagings, extruded parts, e.g. collapsible tubes, tubes, cans, bottles. Furthermore for reflectors, metal signs, large bottles (up to 10 liter), hardware, heat exchanger, pressure vessels, for parts in air fractionation, for heat insulation, aerials, parabolic reflectors, tank and bulk-tank vehicles, body parts, for aircraft construction, tools, moldings and appliances in machine engineering.
