2014 aluminum plate

The alloying element of 2014 aluminum is copper, which is called hard molybdenum, which has high strength and good cutting pin processing performance, but poor corrosion resistance. It is widely used in aircraft structures (skin, skeleton, rib beam, bulkhead etc.) rivets, missile components, truck hubs, propeller elements and various other structural parts.

2014 aluminum is the representative alloy grade in the 2000 series, in addition to 2024 (2A12), LY12, LY11, 2A11, 2A14 (LD10), 2017, 2A17, etc.

The 2XXX series is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better. Many countries produce this alloy, which is the largest amount of duralumin. The characteristics of this alloy are: high strength, certain heat resistance, and can be used as working parts below 150°C. At temperatures above 125°C, the strength of the 2XXX series alloys is higher than that of the 7075 alloy. The forming properties in the hot state, annealing and new quenching state are relatively good, and the heat treatment strengthening effect is remarkable, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by cladding with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by a special process. Widely used in aircraft structures, rivets, truck hubs, propeller components and various other structural parts.
