A356 Aluminum Alloy Castings Composition:

Si content 6.5%-7.5%, Mg content 0.25%-0.45%, Fe ≤0.20%, Cu ≤0.10%, Mn ≤0.10%, Zn ≤0.10%, Ti ≤0.20%, Al balance. It is a heat-treatable aluminum alloy with a fine dendritic structure.

Features:
  • Lightweight & High Strength: Density only 2.68g/cm³, 35% lighter than steel castings, while heat treatment (T6) can improve tensile strength to ≥310MPa, balancing weight reduction and structural stability.
  • Excellent Corrosion Resistance: The dense oxide film formed on the surface and alloy composition make it resistant to atmospheric, freshwater and mild chemical corrosion, suitable for outdoor and marine environments.
  • Good Castability & Machinability: Low melting point, good fluidity, easy to form complex shapes (thin-walled parts, intricate structures); post-casting machining performance is excellent, ensuring high precision.
  • Superior Thermal Conductivity: Thermal conductivity up to 150W/(m·K), 4-5 times that of steel, ideal for heat-dissipating components such as engine parts and electrical enclosures.
Limitations:
  • Lower high-temperature resistance: Above 200℃, mechanical properties decrease significantly, not suitable for long-term high-temperature working conditions.
  • Poor wear resistance compared to steel: Need surface treatment (hard anodizing) for wear-prone parts.
  • Higher cost than ordinary cast iron, but cost-effective considering weight reduction and corrosion resistance.
Applicable Scenarios:

Automotive engine brackets, wheel hubs, cylinder heads; aerospace lightweight components; electrical equipment housings, heat sinks; marine hardware, ship fittings; construction machinery lightweight structural parts.
