Part nameMachined aerospace equipment aluminum alloy 7075 batch parts

Manufacturing processCNC milling

Product Features High processing accuracy, exquisite appearance flawless appearance

【Material used】Aluminum alloy 7075

7005 7075 are representative, mainly containing zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, a super hard aluminum alloy with good wear resistance. The 7075 aluminum plate is stress-relieved will deform warp after processing. All super super All the thick 7075 aluminum plates are ultrasonically detected, which can ensure no blisters impurities. The high thermal conductivity of 7075 aluminum plates can shorten the molding time improve work efficiency. The main feature is that the hardness of 7075 is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft structures futures. It requires the manufacture of high-stress structural parts molds with high strength strong corrosion resistance. At present, basically relying on imports, my country's production technology needs to be improved.

Application scope: aviation (supporting components of aircraft, landing gear), rockets, propellers, aviation ships. )

Surface treatmentspray 120# fine sand, golden hard anodized

①The metal surface sandblasting process method: after degreasing, chemical treatment in the following solution: nitric acid (d=1.41) 3 hydrofluoric acid (42%) 1 soaking at 20°C for 3 seconds, that is, rinse with cold water, then in 65 Wash with hot water at °C, rinse with distilled water, dry. This method is suitable for cast aluminum alloys with high copper content.

②Surface sandblasting process method: chemical treatment in the following solution after degreasing: potassium dichromate 66 sulfuric acid (96%) 666 water 1000 immersed at 70°C for 10 minutes, then washed with water dried.

③Surface sandblasting method: after degreasing, anodize in the following solution: concentrated sulfuric acid 22g/l immersed in 1-1.5A/dm2 direct current intensity for 10-15min, then in saturated potassium dichromate solution, Soak for 5-20min at 95-100°C, then wash with water dry.

Benefits after treatment This part belongs to the appearance of the workpiece, after surface treatment, it is more corrosion-resistant, the appearance is more exquisite in color.

Sandblasting can remove all dirt such as rust on the surface of the workpiece, establish a very important basic pattern on the surface of the workpiece (the so-called matte surface), it can achieve different degrees of roughness by changing abrasives of different sizes. It greatly improves the bonding force between the workpiece the coating plating material.  make the bonding parts more firm better quality.
