2017 aluminum block plate bar

The 2017 aluminum block plate bar 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 2017 aluminum block plate bar 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 2017 alloy 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.
