铝型材由于它的优良电导率而常被选用。在重量相等的基础上，铝的电导率近于铜的两倍。
Aluminum profile is often selected because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper.
热导量率
Thermal conductivity
铝合金的热导量率大约是铜的50-60%，这对制造热交换器、蒸发器、加热电器、炊事用具，以及汽车的缸盖与散热器皆为有利。
The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, cylinder heads and radiators of automobiles.
非铁磁性
Non ferromagnetism
铝型材是非铁磁性的，这对电气工业和电子工业而言是一重要特性。铝型材是不能自燃的，这对涉及装卸或接触易燃易爆材料的应用来说是重要的。
Aluminum profiles are non ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not self ignited, which is important for applications involving handling or contacting flammable and explosive materials.
可机加工性
Machinability
铝型材的可机加工性是优良的。在各种变形铝合金和铸造铝合金中，以及在这些合金产出後具有的各种状态中，机加工特性的变化相当大，这就需要特殊的机床或技术。
The machinability of aluminum profiles is excellent. In all kinds of wrought and cast aluminum alloys, as well as in the various states after the production of these alloys, the machining characteristics change greatly, which requires special machine tools or technologies.
