The material of a gas stove burner directly affects its thermal efficiency, durability, and ease of cleaning:
Copper burner (thermal conductivity approximately 400 W/m·K): Highest thermal efficiency (over 70%), resistant to high-temperature oxidation, but expensive.
Cast iron burner: Durable but prone to rust, thermal efficiency approximately 60%, requires regular maintenance.
Aluminum alloy burner: Lightweight (thermal conductivity approximately 200 W/m·K), low cost, but prone to deformation at high temperatures, shorter lifespan.
Copper offers the best overall performance and is the preferred choice for high-end stoves.
