New Breakthrough in AA7075 Aluminum Alloy Nanotechnology

AA7075 aluminum alloy is an aluminum alloy developed by scientists at a very early time. Although the weight of this aluminum alloy is only one-third of that of steel, its hardness is almost the same as that of steel, so the use of this material can be Vehicles are lighter and more energy-efficient, and are generally used in aircraft fuselage and wings.

In the past, AA7075 aluminum alloy has always had a problem that it cannot be welded. During the heating process, the molecular structure will flow unevenly, which will lead to cracks in the welded product;

Engineers at the University of California, Los Angeles, have developed "a billionth of a meter volume of titanium carbide nanoparticles added to the wire of AA7075", so that the particle welding material can be used.

Products welded by this method will not produce gaps and can reinforce this aluminum alloy, so AA7075 can be widely used, such as industrial fans, whose fan hubs are made of AA7075 super-hard aluminum alloy through high-pressure precision forging.
