3003 aluminum sheet is a widely used anti-rust aluminum sheet, and it still has a long service life in some humid environments. Thermal conductivity refers to the heat transfer through an area of 1 square meter within a certain period of time for a material with a thickness of 1m and a temperature difference of 1 degree (K, ℃) between the two sides of a material under stable heat transfer conditions. The unit is W/m·degree (W/(m·K), where K can be replaced by °C). Aluminum 3003 thermal conductivity at 20 degrees Celsius, the O temper is 193W/(m*K)annealed state, 163W/(m*K) in the H12 temper, 159W/(m*K) in the H14 temper, and 155W/(m*K) in the H18 temper .

aluminum 3003 thermal conductivity

Heat dissipation depends on the 3003 aluminum thermal conductivity, determined by the thermal conductivity of the metal. The larger the thermal conductivity, the better the heat dissipation. Insulation pipes are required to have the characteristics of low thermal conductivity, low density, high flexibility, fireproof and waterproof. Aluminum alloy materials are often used in the production of pipe insulation materials. Common materials are 1060 aluminum coils and 3003 aluminum sheet, with a thickness of 0.3-1.0mm.


Aluminum 3003 thermal conductivity is good, the thermal conductivity is between 20°C and 300°C, and the average value is 238W/(m K), but as the temperature increases, the thermal conductivity will also decrease. In addition, the thermal conductivity of 3003 aluminum alloy is also affected by the composition, structure, and thickness of the material. Most of the time it has lower thermal conductivity than pure aluminum due to factors such as temperature, but it is stronger than pure aluminum in terms of thermal expansion.
