The introduction of 2017 aluminum block bar rod
The 2017 aluminum block bar rod is a typical hard aluminum alloy in the Al-Mg-Cu series. Its composition is reasonable and its comprehensive performance is good. It is the larger amount of hard aluminum.

The characteristics of 2017 aluminum block bar rod are:
1. High strength and certain heat resistance, can be used as working parts below 150 ° C.
2. The temperature is higher than 125 ° C. The strength of 2017 alloy is higher than that of 7075 alloy.
3. The forming performance is better in the hot state, annealing and new quenching states, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict.
4. Poor corrosion resistance, but covered with pure aluminum can be effectively protected; cracks are easy to occur during welding, but special processes can be used for welding and riveting.
