Die-cast aluminum and aluminum alloy each have their own advantages and disadvantages,
and the choice depends on the specific application scenario and performance requirements.
Comparison of material properties
Die-cast aluminum:
Usually refers to aluminum alloys formed by die-casting process, with a high silicon content (such as ADC12 containing 10%-12% silicon), good fluidity but large shrinkage (5-6‰).
Suitable for complex structural parts, such as automobile engine housings, radiators, etc., with high production efficiency and economy.
Conventional aluminum alloys:
Covering a wider range of alloy systems (such as 6 series aluminum magnesium silicon, 7 series aluminum zinc magnesium, etc.), can be formed by extrusion, forging and other processes, with better strength and corrosion resistance.
Suitable for scenes with high requirements for strength and lightweight, such as building profiles and aerospace components.
Key performance differences
Strength and weight: Aluminum alloys (such as 7075) have higher specific strength, but die-cast aluminum can achieve thin-walled complex structures due to process advantages.
Surface treatment: Die-cast aluminum contains high silicon, and anodizing is prone to water marks, which is suitable for spraying; aluminum alloy oxidation has better effect.
Cost and efficiency: Die-cast aluminum is suitable for mass production and has a long mold life; aluminum alloy extrusion process is flexible but the unit cost is high.
Application scenario recommendations
Die-cast aluminum is preferred: parts that require rapid prototyping and complex structures (such as electronic housings and automotive parts).
Aluminum alloy is preferred: scenes that require high strength, corrosion resistance or surface oxidation (such as building curtain walls and aviation parts).
