The design achieves the ideal harmony between low weight and great strength.
Aluminum alloy has a density only one-third that of steel, but alloying (like the Al Mg Si and Al Cu Mg series) can give it a tensile strength of over 300 MPa, making it perfect for applications that need both "lightweight and high rigidity." This includes aircraft structural parts, car chassis, and more. For instance, the Airbus A350 fuselage makes extensive use of aluminum alloy elements, thereby lowering weight by 15% to 20% relative to conventional materials and greatly cutting fuel usage.
Very good machinability.
Little cutting force: Aluminum alloys are characterized by their low hardness (HB 80–150) and a tool wear rate that is only one-third to one-fifth of that of steel. Higher speeds (up to 20,000 rpm) and feed rates made possible by it enable a machining efficiency improvement of more than 30%.
High thermal conductivity (170 W/m·K): The cutting heat quickly spreads to keep the workpiece's dimensions within ± 0.01 mm, which is especially important for high-precision items like precision molds and semiconductor equipment.
Aluminum chips are simple to fall off, so they prevent chip grooves from clogging and provide constant processing stability.
Mismatched geometric correctness
Multi-axis linkage technology with high-precision CNC machine tools (with a repeat positioning accuracy of ≤ ± 0.003 mm) enables:
Extremely thin wall construction Medical implant catheters and other complex cavity components with a wall thickness of ≤ 0.5 mm show no distortion or cracking.
Complex surface development: With surface roughness Ra ≤ 0.4 μm, five-axis linkage machining of irregular components, including flow channels and impeller blades, results in a streamlined design to improve aerodynamic performance.
Microscale detail carving: laser-assisted CNC machining of very small hole arrays (aperture ≤ 0.1 mm) is being worked on for 3D printing nozzles and sensor chip carriers.
Integrated production combined with modular designs
By using CNC one-time molding, achieve multi-component integration-such as drone wings and control surfaces-and so lower assembly tolerances by 60% cumulatively.
Topological optimization framework: Using finite element analysis, hollow mesh design, like that found in car battery brackets, makes the structure 30% lighter while increasing its torsional rigidity.
Surface strengthening process Hard anodizing: a ceramic layer 20–25 μm thick, hardness up to HV 1500–2000, 10 times more wear resistance, good for engine piston rings and bearing seats. Micro-arc oxidation generates a glass-ceramic layer of 50-200 μm on the surface, resistant to high temperature (1200℃) and corrosion (salt spray test > 2000 hours), used for aerospace seals. Chemical passivation: creates a thick oxide film (5–15 μm) to improve anti-fingerprint and anti-fouling properties, suitable for the cases of consumer electronics. Functional coatings and modifications Electroplated nickel/gold: conductivity increased to 10⁴ S/cm, meeting the requirements of circuit board connectors and high-frequency signal shielding covers. PTFE/Teflon spray coating: friction coefficient reduced to 0.05, used for food machinery guide rails and medical device catheters. Laser micro-nano processing: Make small pits (Ra = about 0.1 μm) on the surface to get superhydrophobicity (contact angle > 150°) or properties that clean themselves.
EADS satellite camera components: CNC-machined titanium-aluminum alloy composite bracket, effectively utilized for Beidou navigation satellite, reduces weight by 40%.
With a fatigue life of 10⁶ cycles, aircraft fasteners are AA7075 aluminum alloy rivets, heat-treated (T6 state) and CNC precision-made.
Modern energy cars
A one-piece die-cast aluminum alloy chassis, CNC-cut heat dissipation holes, and installation slots lower weight by 25% compared to a steel construction and increase driving range by 12%.
The battery module bracket is made of 6-series aluminum alloy laser welding, CNC milling, and a CTB (cell-to-body) integrated design, which gives it an extra 30% strength.
