1. Lightweight. The main material of cast aluminum tables and chairs is aluminum and aluminum alloy, which has a lower density than steel and iron, making it lightweight.

2. Excellent thermal conductivity. Aluminum boasts good thermal conductivity among most metals, with a melting point of 2,327°C, rapid heat absorption and dissipation, and excellent耐火 properties.

3. Excellent rust and corrosion resistance. Cast aluminum alloys inherently possess rust and corrosion resistance due to the protective layer of aluminum oxide on their surface. Typically, outdoor furniture manufacturers apply spray painting and baking varnishing treatments to the cast aluminum during the manufacturing process to reinforce its rust-resistant properties.
