What are 3 examples of materials that make good conductors?
Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Which of these materials is a good conductor of heat?
Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. These conductive properties are rated based on a “coefficient” which is measured relative to silver.
What are materials that conduct heat?
Here’s a ranking of heat conducting metals and metal alloys from lowest to highest average thermal conductivity, in Watts/meter-K at room temperature:
- Stainless Steel (16)
- Lead (35)
- Carbon steel (51)
- Wrought iron (59)
- Iron (73)
- Aluminum Bronze (76)
- Copper brass (111)
- Aluminum (237)
Why some materials are good conductors of heat?
Thermal conduction occurs when particles of warmer matter bump into particles of cooler matter and transfer some of their thermal energy to the cooler particles. Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily.
What are good thermal conductors?
Thermally conductive materials

- Aluminum – 247 W/m•K.
- Tungsten – 173 W/m•K.
What is the best heat conductor?
Good Heat Conductors Metal is a good heat conductor because it lets heat flow through it easily. Copper and silver are the best heat conductors. Copper conducts heat ten times better than iron. When heat travels by conduction through a heat conductor, the heat is passed on from one atom to the next. The heat flows, the heated atoms don’t!
What is the best thermal conductor?
Silver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.
What materials conduct heat?
Basically, when it comes to conducting heat, not all substances are created equal. Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat.
