What is thermal conductivity of Aluminium?
Thermal Conductivity. – k – (W/m K) Aluminum. -73.
What are the properties of Aluminium metal?
Aluminum Characteristics
- Non-corrosive.
- Easily machined and cast.
- Lightweight yet durable.
- Non-magnetic and non-sparking.
- Good heat and electrical conductor.
Is aluminum a good conductor of thermal energy?
As you can see, out of the more common metals, copper and aluminum have the highest thermal conductivity while steel and bronze have the lowest. As copper is an excellent conductor of heat, it’s good for heat exchangers, heat sinks, and even saucepan bottoms.
What is the thermal resistance of Aluminium?
Thermal Contact Resistance

|---|---|---|
| Contact Pressure | 100 kN/m2 | 10,000 kN/m2 |
| Copper | 1-10 | 0.1-0.5 |
| Magnesium | 1.5-3.5 | 0.2-0.4 |
| Aluminum | 1.5-5.0 | 0.2-0.4 |
What is the thermal conductivity of the metal?
High k value: High thermal conductivity

What are the properties of Aluminium Class 10?
Properties of Aluminium
- The element is highly reactive. It has about one-third of stiffness and density of steel.
- Aluminium has good corrosion resistivity.
- It is capable of superconductivity.
- They are many unknown isotopes of hydrogen with the mass number ranging from twenty-one to forty-one.
Is aluminum a conductive metal?
Conductors consist of materials that conduct electric current, or the flow of electrons. Nonmagnetic metals are typically considered to be ideal conductors of electricity. The wire and cable industry uses a variety of metal conductors, but the two most common are copper and aluminum.
Which metal has more thermal conductivity?
Diamond – 2000 – 2200 W/m•K. Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer.
