1. Material development
The emergence of high-performance aluminum alloys
New alloy research and development: such as the high-strength and heat-resistant 7000 series (7075, 7A04) and the corrosion-resistant 5000 series (5052, 5083), as well as ultra-light and high-strength alloys with the addition of elements such as scandium and lithium (such as Scalmalloy), promote applications in aerospace, automotive and other fields.
Aluminum-based composite materials: Add reinforcements such as ceramics and carbon fibers to improve wear resistance and thermal stability to meet the needs of semiconductor equipment and robot precision parts.
Recycled aluminum alloys: Driven by the circular economy, the proportion of recycled aluminum has increased (such as the proportion of recycled aluminum used in automobiles has reached more than 60%), reducing costs and being environmentally friendly.
Material performance optimization
Through heat treatment (such as aging hardening) and microstructure
regulation (such as grain refinement), the balance between strength
and toughness is improved to adapt to complex working conditions.
2. Processing technology trends
High-precision manufacturing technology
Upgrade of CNC machine tools (CNC): Five-axis linkage and
high-speed milling technology achieve micron-level precision to
meet the needs of precision parts such as medical devices and
optical devices.
Additive manufacturing (3D printing): Laser selective melting
(SLM) technology forms complex structures (such as conformal
cooling channels), shortens the R&D cycle, and is applied to
aerospace customized parts.
Micro-machining: Micro-electro-spark (EDM) and electrochemical
machining (ECM) achieve sub-millimeter-level parts production,
adapting to micro-components such as electronic connectors.
Surface treatment innovation
Anodizing and micro-arc oxidation: Improve corrosion resistance,
wear resistance and aesthetics to meet the needs of consumer
electronics (such as mobile phone housings) and outdoor industrial
parts.
PVD/CVD coating: Super-hard wear-resistant layer (such as TiAlN)
is achieved through physical/chemical vapor deposition to extend
mold life.
III. Expansion of application areas
New energy vehicles
Demand for aluminum alloy battery trays, motor housings, and body
structural parts has surged, and lightweighting has helped improve
endurance (weight reduction of more than 30%).
Integrated die-casting technology promotes the integration of large
structural parts and reduces manufacturing costs.
Aerospace
High-strength aluminum alloys are used for fuselage skins and
landing gears, combined with 3D printing to manufacture
topologically optimized components, reducing weight while improving
reliability.
Electronic equipment
5G base stations and chip heat sinks rely on high thermal
conductivity aluminum alloys (such as A380), and micro-precision
machining is adapted to semiconductor equipment components.
Industrial automation
Robot joints and reducer housings are made of aluminum alloys,
taking into account lightweight and high rigidity to meet the needs
of precision motion control.
IV. Market demand drive
Lightweight rigid demand
Carbon emission regulations in various countries are becoming
stricter, and aluminum alloys are accelerating the replacement of
steel in the automotive and rail transportation fields (such as
Tesla's integrated die-casting technology).
The new energy field (drones, power tools) pursues lightweight
design, promoting the demand for customized high-strength aluminum
alloys.
Consumption Upgrade
The demand for ultra-thin, high-strength structural parts in
consumer electronics is growing (such as MacBook shells and folding
screen hinges).
The trend of miniaturization and precision of smart home devices
(such as sweeping robots) drives customized processing.
V. Challenges and Responses
Balance between Cost and Efficiency
High-precision processing equipment requires high investment, and
it is necessary to reduce costs and increase efficiency through
automation (such as robot loading and unloading) and process
optimization (such as high-speed cutting parameters).
Breakthrough in Technical Barriers
Cutting parameter optimization and thermal deformation control of
complex alloys are key, and it is necessary to strengthen
industry-university-research cooperation (such as building R&D
centers with universities).
Environmental Compliance
The treatment of wastewater and waste gas in surface treatment
processes must meet ESG requirements and promote the application of
green processes (such as cyanide-free electroplating and dry
cutting).
Sixth, Future Outlook
Intelligent Manufacturing: AI process optimization and digital
twin technology improve yield and promote flexible customized
production.
Cross-border Integration: Combine aluminum alloys with
composite materials, ceramics, etc. to develop ultra-performance
heterogeneous structural parts.
Global competition: Chinese processing plants need to increase
their technological added value and shift from low-end OEM to
high-margin precision parts
suppliers.
