Regarding the thermal conductivity coefficients of various aluminum profiles, the thermal conductivity coefficient of extruded aluminum is as follows:
| Name | Model | Thermal conductivity (S/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 |
| Cast aluminum | A360 | 113 |
| Cast aluminum | A380 | 96.2 |
Grades:
1. ADC12, compared to ADC10, contains more silicon, has higher strength, superior pressure resistance and excellent thermal brittleness. Therefore, it is suitable for casting complex components.
2. The thermal conductivity of plastic is quite low, approximately 1/500-1/600 of that of metals.
3. The thermal conductivity of plastic foam 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 -an ideal insulating material.
