FAQS on die cast aluminum material properties

Q: What are the key properties of die cast aluminum?

A: Die cast aluminum offers high strength-to-weight ratio, excellent thermal conductivity, and corrosion resistance. Its fluidity in molten state enables complex shapes with tight tolerances. It's widely used for lightweight, durable components.

Q: Why is aluminum a preferred material for die casting?

A: Aluminum's low melting point reduces energy costs, while its natural oxidation resistance minimizes surface defects. The material maintains dimensional stability and supports high-volume production with consistent quality.

Q: What materials are used for die casting molds?

A: Die casting molds typically use heat-resistant tool steels like H13 or maraging steel. These materials withstand repeated thermal cycling up to 600°C and resist molten aluminum erosion. Surface treatments like nitriding enhance mold longevity.

Q: How does die cast aluminum compare to other die cast materials?

A: Aluminum die casting provides better strength and heat dissipation than zinc alloys, while being lighter than magnesium alternatives. It outperforms plastics in high-temperature applications and offers superior EMI shielding.

Q: What factors determine die casting mold material selection?

A: Key considerations include production volume, part complexity, and thermal stress requirements. High-grade tool steels with chromium and tungsten content are chosen for aluminum die casting due to their thermal fatigue resistance and hardness retention.
