Most of the problems related to aluminum wire are typically associated with older (pre-1972) AA-1350 alloy solid aluminum wire, sometimes referred to as "old technology" aluminum wiring, as the properties of that wire result in significantly more expansion and contraction than copper wire or modern day AA-8000 series aluminum wire.
This improved conductivity over bare aluminum makes the copper-clad aluminium wire a good fit for radio frequency use. The skin effect is similarly exploited in copper-clad steel wire, such as the center conductors of many coaxial cables , which are commonly used for high frequency feedlines with high strength and conductivity requirements.
These thermal greases have low electrical conductivity and their volume resistivities are 1.5⋅10 15, 1.8⋅10 11, and 9.9⋅10 9 Ω⋅cm for 860, 8616 and 8617 respectively. The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride.
Inductor made with magnet wire wound around a toroidal core. Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation.It is used in the construction of transformers, inductors, motors, generators, speakers, hard disk head actuators, electromagnets, electric guitar pickups, and other applications that require tight coils of insulated wire.
ACSR cable still depends on the tensile strength of the aluminium; it is only reinforced by the steel. Because of this, its continuous operating temperature is limited to 75 °C (167 °F), the temperature at which aluminium begins to anneal and soften over time. [2]

The mechanical properties of 7075 depend greatly on the tempering of the material. [7] Aluminum 7075 has a low formability at low room temperature and is vulnerable to stress corrosion cracking. Using different elevated temperature forming techniques has been shown to reduce springback and fracture. [8]
Au 5 Al 2 has low electrical conductivity and relatively low melting point. Au 5 Al 2 's formation at the joint causes increase of electrical resistance, which can lead to electrical failure. [ 3 ] Au 5 Al 2 typically forms at 95% of Au and 5% of Al by mass, its melting point is about 575 °C, which is the lowest among the major gold-aluminum ...
