Abstract: The effect of the desaturation aging (DSA) treatment on the strength and the corrosion resistance of ultra high strength aluminium alloys were studied.
The dial shall be made of copper aluminum alloy, inalterable black numerals and graduation on white background. The manufacture of same will be to applicable standards.
Air hole, burnthrough, cooapse and welding crackle occurred in the fixed overhead weld for aluminium and aluminium alloy tubes, above all the small-size thin wall tube.
The process for brush plating mending of deeply scratched surface of LY12 duralumin alloy was introduced. The merits of the brush plating mending technology of LY12 duralumin alloy were discussed.
One thing that has been happening in the field of aircraft manufacturing is that the aircraft are becoming lighter thanks to use of composite materials, as opposed to the aluminum or aluminum.
