WebMay 8, 2012 · The Al-Cu alloys were prepared with a nominal 50 : 50% atomic concentration and deposited with 50, 100, 150, 200, and 250 nm as total thickness. The corresponding individual film thicknesses for this atomic concentration were calculated as 𝑡 A l = 58.4% and 𝑡 C u = 41.6% of the total thickness. WebRich in aluminium, this alloy is hence endowed with the desirable characteristics of low electrical resistivity and low density for optimal frequency response. The role of copper, which accounts for only about 2 percent of the weight of the AlCu alloy, is to serve as a "˜glue' between the aluminium grains to reduce hillock and void formation.
