Description

The material EN AW-Al Cu4Mg1 is produced for sheet, strip and plates, for extruded and drawn components, for forged parts and prematerial. The alloy is not food-safe. To the comparable mark AlCuMg2, material No. 3.1355, acc. to DIN 1725-1 applies: The alloy (see also AlCuMg2, Werkstoff-Nr. 3.1454, nach denWerkstoffleistungsblättern der Deutschen Luftfahrt WL 3.1354-1,-2,-3 :1987-12, WL 3.1354-4,-100 : 1990-01 and Beiblatt 1 zu WL 3.1354 and 3.1364) pertains to the alloy-type (AlCuMg-Typ) used as the first of the aluminium- forgeable materials in technics. Alloys of this type are usable for natural and artificial aging. They achieve high mechanical strength and they are relatively heat-resistant even in a soft condition. In age hardened condition the material achieves strength up to approx. 480 N/mm² what is the highest within the AlCuMg materials. Heat-treatment for hardening: Solution annealing: 495° to 505°C, quenching in water Natural aging: 5 to 8 d at RT Artificial aging:16 to 24 h at 180 to 195°C Artificial aging is impossible in practice due to the decreasing corrosion resistance in artificially aged material condition. Even in a naturally aged condition is a surface protection necessary. Considerable strength decrease as well as complicate weldability and hot workability of this alloy as a result of insignificant heat-treatment failures are very unfavorable. Additionally, by welding is caused an economically unacceptable strength loss in the weld seam sector. The application of this material in welding constructions is for economical reasons impossible. It has a very favorable machinability what justifies the application of screws and rivets as connecting elements. The alloy AlCuMg1 is particularly well suitable for construction parts of a higher static load. Application: in machine engineering (incl. mold making) for tools, machine benches, hydraulic turned parts (hydraulics/pneumatics),appliances (anchor plates, head and punch unit holder plates as well as guide plate). As connecting elements (screws, solid rivets), in vehicle engineering as bumper, body and safety parts and in transport for air freight container as well as in aircraft construction. The material is one of the most important aviation materials.
