抗腐蚀性
Corrosion resistance
铝型材的密度只有2.7g/cm3,约为钢、铜或黄铜的密度(分别为7.83g/ cm3,8.93g/ cm3),的1/3。在大多数环境条件下,包括在空气、水(或盐水)、石油化学和很多化学体系中,铝能显示优良的抗腐蚀性。
The density of aluminium profile is only 2.7g/cm3, which is about 1/3 of that of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in air, water (or brine), Petroleum Chemistry and many chemical systems.
电导率
conductivity
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 profiles are often selected because of their excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminium 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 aluminium alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as the cylinder head and radiator 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 characteristic for the electrical and electronic industries. Aluminum profiles cannot spontaneously ignite, which is important for applications involving handling or contact with 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 aluminium profile is excellent. In all kinds of deformed and cast aluminium alloys, as well as in all kinds of States after the production of these alloys, www.apsaLu.cn www.hunLiaoji.com.cn www.jnkeqing.cn www.hanyubw.cowww.ccdrc.cn www.bjguomei.cnthe machining characteristics change considerably, which requires special machine tools or technologies.
可成形性
Formability
特定的拉伸强度、屈服强度、可延展性和相应的加工硬化率支配着允许变形量的变化。
Specific tensile strength, yield strength, ductility and corresponding work hardening rate control the variation of allowable deformation.
回收性
Recyclability
铝具有极高的回收性,再生铝的特性与原生铝几乎没有区别。
Aluminum has very high recyclability, and the characteristics of recycled aluminium are almost the same as that of primary aluminium.
