2090 aluminum lithium alloy profile

2090 aluminum lithium alloy profile has been widely used in aerospace field because of its good specific strength, specific stiffness and fatigue resistance .

2090 aluminum lithium alloy profile has attracted much attention in the field of aerospace, because aerospace has strict lightweight requirements for the selected materials. Usually, light and high-strength materials are mainly selected, such as composites, titanium alloys and magnesium alloys. Lithium is the lightest metal element. After adding lithium to aluminum alloy, the density of the alloy decreases, the specific strength and specific stiffness increase, and it also has good corrosion resistance and fatigue resistance. 2090 aluminum lithium alloy profile has great potential in weight reduction, so it is widely used in the In R & D and production of aerospace equipment.

In the future, 2090 aluminum lithium alloy profile will gradually replace traditional aluminum alloy:

(1) In the research of ultra-low density, light weight has always been the main advantage of 2090 aluminum lithium alloy profile. Through the exploration of the lithium content of 2090 aluminum lithium alloy profile , it can reduce the alloy density and have better strength and plastic toughness;

(2) Super strength and super toughness, excellent strength, tensile strength over 760 MPa and yield strength over 740 MPa, so 2090 aluminum lithium alloy profile has great potential in high strength and high toughness;

(3)2090 aluminum lithium alloy profile can be seen that the comprehensive performance of 2090 aluminum lithium alloy profile still has the potential to improve. Its future stage is not only in the field of aerospace, but also can be popularized and applied to all aspects of civil life.
