Regarding the thermal conductivity coefficients of various aluminum profiles, the thermal conductivity coefficient of extruded aluminum is as follows:
| Name | Model | Thermal Conductivity (W/m·k) |
| Pure Aluminum | / | 237 |
| Aluminum Alloy | 1050 | 209 |
| Aluminum Alloy | 1070 | 226 |
| Aluminum Alloy | 6061 | 155 |
| Aluminum Alloy | 6063 | 201 |
| Aluminum Alloy | ADC12 | 96.2 |
| Die-Cast Aluminum | A360 | 113 |
| Die-Cast Aluminum | A380 | 96.2 |
Notes:
1. ADC12, compared to ADC10, contains more silicon, has greater strength, superior pressure resistance, and excellent thermal brittleness. Hence, it’s well-suited for casting complex components.
2. The thermal conductivity of plastic is quite low, roughly 1/500-1/600 that of metals.
3. The thermal conductivity of foam plastic is only 0.02-0.046 W/m·k, approximately 1/1500 of that of metals, 1/40 of that of cement concrete, and 1/20 of that of ordinary clay bricks, making it an ideal insulating material.
