The 2017 alloy element is copper, known as hard molybdenum, which has high strength and good cutting and machining properties, but poor corrosion resistance.It is widely used in aircraft structures (covering, frame, ribbed girder, frame, etc.) rivets, missile components, truck wheel hub, propeller components and other structural parts.
2017 Aluminum bars are used where high strength and hardness (including high temperature) are required.Heavy forgings, thick plates and extruded materials are used for aircraft structural parts, first stage fuel tanks for multistage rockets and spacecraft parts, wheels, truck frames and suspension system parts.2017 aluminum rod has poor corrosion resistance, but it can be effectively protected by using pure aluminum coating, and it is easy to generate cracks when welding, but it can be welded or riveted with special technology.Aluminum rods are widely used in aircraft structures, rivets, truck wheel hubs, propeller components and other structural parts.
