With the rapid development of aerospace industry, higher and higher requirements have been put forward for semi-finished products of aluminium alloys, especially for high-speed military and civil aircraft, in order to make the structure of each component more cohesive force, ensure the minimum quality of structure, the maximum strength and rigidity, and reduce the number of components substantially. Reduce the cost of assembly, bonding and maintenance, ensure the perfect and beautiful surface (good sealing, seamless, no deformation, etc.). As a result, large-scale aluminium alloy profiles have become an important object of research and development all over the world. At present, large, complex and integral
special alloy aircraft grade aluminum tubing have become an indispensable important structural material in the aviation industry.
The requirements for
aircraft grade aluminum tubing are as follows:
1. Large-scale
aircraft grade aluminum tubing belong to the important structural parts of aircraft, which require profiles to have excellent mechanical properties. This kind of pipe must be extruded by hard or superhard aluminium alloy.
2. Complex shape, wide size and large cross-sectional area.
3. As a key component of the aircraft, it is required to have good comprehensive performance and uniform structure, especially for coarse-grained rings. It is difficult to avoid the defects of coarse grained rings in quenched products after extrusion, and it is also one of the research topics that the extrusion workers all over the world have struggled for decades and have little effect.
