Thermal conduction and energy storage pure aluminum

Why does aluminum have a lower thermal conductivity?

For example, aluminum alloys with copper, silicon, magnesium and other elements usually have a lower thermal conductivity because the addition of these elements may change the lattice structure and electron flow inside the material, thereby affecting the conduction of heat. Temperature The thermal conductivity of aluminum changes with temperature.

How does purity affect the thermal conductivity of aluminum?

Purity of the material The purity of aluminum directly affects its thermal conductivity. Pure aluminum has a high thermal conductivity, but in actual production and application, aluminum is usually alloyed to increase its strength and hardness. The addition of different alloying elements will affect the thermal conductivity of aluminum.

What is the theory of thermal conduction of aluminum alloys?

The theory of thermal conduction of metals can investigate the effect of alloying elements and temperature on the thermal conductivity of aluminum alloys. Moreover, aluminum alloys can be regarded as composites composed of an aluminum matrix and secondary phases.

Why is aluminum important for heat management?

Aluminum is key to heat management because of its thermal properties. Its high thermal conductivity and specific heat capacity make aluminum perfect for applications that need heat transfer and temperature control.

What is thermal conductivity?

Thermal conductivity measures how efficiently heat is transferred across a unit cross-section when there is a temperature gradient normal to the direction of heat flow .

How does solution treatment affect the thermal conductivity of aluminum alloys?

The former will reduce the thermal conductivity, and the latter (increased sphericity of eutectic Si) will increase the thermal conductivity. Therefore, the effect of solution treatment on the thermal conductivity of aluminum alloys depends on the dissolution and variation in the morphology of secondary phases. 4.2.2. Aging Treatment
