5A02/5A03/5A05 Aircraft Aerospace Aluminum Extrusions Section for Aviation

5A02/5A03/5A05 Aircraft Aerospace Aluminum Extrusions Section for Aviation    5A03 aluminium alloy sheet profile forgings is an alloy with moderate Mg content in 5 * * * system, with low strength and high plasticity. Cold deformation can improve its strength, but the plasticity will decrease. In aircraft manufacturing, we need to manufacture welded medium load parts, such as pipes, liquid containers and skeletons, which need high technological plasticity and high corrosion resistance.The melting temperature of 5A03 is 700~750 ºC, and the casting temperature is 690~730ºC. 5A03 alloy has quite high corrosion resistance. The die forging temperature of 5A03 is 420~475ºC, and the deformation rate in this temperature range is more than 80%. 5A03 alloy wire does not form weld when it is made of solder, and the strength of the weld can be 90%~95% of the matrix material, and it has high plasticity at the same time. The machinability and grinding performance of the O state material are not good, and the H state material is better.  Calibration mechanical strength of 5A03 aluminum alloy sheet profile forgingsTechnical standardTypeTemperδ  or d/mmTension strength Rm/MpaRp0.2/MpaA/%GB/T 3880Aluminum sheetO0.5~4.5≤195≥100≥16H14>0.5~4.5≥225≥195≥8H24H34H112>4.5~10.0≥185≥80≥16>10.0~12.5≥175≥70≥13>12.5~25.0≥175≥70≥13>25.0~80.0≥165≥60≥12GJB 2503Aluminum sheetO0.5~4.0≤196≥98≥15H×40.5~4.0≥225≥196≥8GJB 2662Aluminum plateH1127~10≥186≥78≥15>10~25≥176≥67≥12>25~50≥167≥59≥11GB/T 3191Extruded aluminum round barH112, O≤150≥176 ≥78≥13GJB 2504Extruded aluminum round bar5~250HB 5202Extruded aluminum round bar≤240GJB 2507Extruded aluminum round barH112, OAll≥176≥78≥12GB/T 4437Aluminum pipeH112All≥176≥69≥15GJB 2381 H112, OOD25~250Wall thickness 5~35≤240 -GJB 2379Cold drawn aluminum pipeOAll≤177≥78≥15H×4All≥215≥127≥8GJB 2351Free forgings, die forgingsH112As agreed≥186≥78≥15HB 5204    /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
