簡單介紹:
7050鋁棒屬高強度可熱處理合金,具有極高的強度及抗剝落腐蝕和抗應力腐蝕斷裂的性能。
詳情介紹:

7050化學成分


鋁(Al) 余量

鉻(Cr)≤0.04

鋯(Zr)0.08~0.15

鋅(Zn)5.7~6.7

硅(Si)≤0.12

鐵(Fe)0.000~0.150

錳(Mn)≤0.10

鎂(Mg)1.9~2.6

鈦(Ti)≤0.06

銅(Cu)2.0~2.6

7050鋁棒屬高強度可熱處理合金,具有極高的強度及抗剝落腐蝕和抗應力腐蝕斷裂的性能。常用于飛機結構件用于中厚板 擠壓件、自由鍛打件與模鍛件。制造這類零件對合金要求:抗剝落腐蝕性與抗應力腐蝕開裂能力、斷裂韌性與抗疲勞性能都強。

7075系鋁合金主要合金元素是鋅,向含3%-75%鋅的合金中添加鎂,可以形成強化效果顯著的MgZn2,使該合金的熱處理效果遠遠勝過鋁鋅二元合金.提高合金中的鋅鎂含量,抗拉硬度就得會到進一步的提高,但其抗應力腐蝕和抗剝落腐蝕的能力會隨之下降.經熱處理,能達到非常高的強度特性.該系材料一般都會加入商量銅鉻等合金.該系中以7075-T651鋁合金為上品,被譽為鋁合金中*優良的產品,強度高,遠勝于軟鋼.此合金具有良好的機械性能及陽極反應.主要用于航空航天,模具加工,機械設備.工裝夾具,特別用于飛機制造結構及其它要求強度高,抗腐蝕性能強的高應力結構體.
