- High strength and corrosion resistance
Lightweight and Energy Efficiency
Die cast alloys, such as aluminum and magnesium alloys, have become important materials for automotive lightweighting due to their low density and high specific strength.
- Lightweight not only helps reduce the overall weight of the vehicle, but also significantly improves fuel efficiency and reduces emissions. For example, research has shown that reducing a car’s weight by 10% can increase its range by 5-6%.
- In addition, with the rise of electric vehicles (EVs), the weight of battery packs and electric drive systems has increased, leading to a further increase in demand for lightweight materials.
- The application of aluminum alloy and magnesium alloys in key components such as battery casings and motor casings can help improve the range and energy efficiency of electric vehicles.

lightweight design
One of the core advantages of die-casting technology in the aerospace industry is its ability to achieve lightweight design.
- Aluminum and magnesium alloys are ideal choices for aerospace components due to their excellent strength to weight ratio.
- For example, aluminum silicon alloys (such as ADC12, A380) and magnesium alloys (such as AZ91D) can be used in the die-casting process to manufacture lightweight but high-strength components.
- It significantly reduces the total weight of the aircraft, improving fuel efficiency and flight performance.
Manufacturing of complex geometric shapes
Die casting technology can produce parts with complex geometric shapes, including thin-walled structures and fine details.
This ability enables die-casting technology to manufacture components in the aerospace industry that are difficult to achieve with traditional casting processes, such as wing ribs, brackets, engine casings, etc.
High precision and surface quality
Die casting technology can achieve high-precision dimensional control and good surface quality.
- This enables die-casting components to meet strict assembly and functional requirements in the aerospace industry.
- For example, aluminum die castings typically have high dimensional accuracy (up to level 4) and low surface roughness (up to level 5), and can be used directly without further processing.
Die casting alloys application: Consumer electronics
Die casting uses in the consumer electronics industry to produce electronic equipment housings, aluminium radiator, heat sinks, connectors and other parts.
- Shell and structural components
- Radiators and Thermal Management Systems
Shell and structural components
Die casting technology can produce lightweight, high-strength casings and structural components, such as casings for smartphones, laptops, tablets, etc.
- These shells not only need to have good mechanical strength, but also need to have good heat dissipation performance.
- For example, aluminum silicon alloys (such as A380, A383) are widely used in the manufacture of electronic device casings due to their excellent thermal conductivity and corrosion resistance.
- In addition, magnesium alloys such as AZ91 are also used to manufacture casings for devices such as mobile phones and cameras due to their lightweight and high-strength characteristics.
Radiators and Thermal Management Systems
Die casting technology also plays an important role in the thermal management system of electronic devices.
- Aluminum alloy and magnesium alloy have excellent thermal conductivity, which can quickly dissipate the heat inside the equipment to the external environment.
- For example, aluminum silicon alloy is commonly used to manufacture fins and fins for heat sinks to improve heat dissipation efficiency.
- In addition, die-casting technology can directly integrate heat dissipation channels into structural components, thereby reducing reliance on additional cooling systems
- Due to its high precision and excellent thermal management performance, die-cast aluminum products are particularly suitable for applications that require heat dissipation.
