Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu (Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).

Al-Cu类合金是工业上最早使用的铸铝合金。 其主要性能特点是室温和 高温力学性能 高，铸造工艺简单，切削加工性能好，耐热性能优良，是发展含Cu 高强度铝合金 和各种 耐热合金 的基础。

We explain the differences between COALR, CO/ALR devices and AL-CU or CU-AL devices - they are not equivalent! Aluminum wire connections can overheat enough to start a fire without ever drawing enough current to trip a circuit breaker.

2020年3月1日 · We characterize the Cu-Al solid-liquid interface through the calculation of profiles for mean square displacement (MSD), diffusion coefficient, atomic concentration distribution, diffusion layer thickness, radial distribution function (RDF). We also find the relationship between the calculation profiles and temperature, time, pressure.

2020年6月1日 · The Cu-Al alloys with three Al contents, nine grain sizes induced by the controlled annealing treatment, and three gradient structures induced by 3S treatment were prepared, and the improvement of strength and ductility, trade-off relation between strength and ductility were explored in this work.

Al-Cu系铸造铝合金是指以铜为主要合金元素的铸造铝合金。 铜的含量范围在1-11%。 含铜9%以上的Al-Cu系合金，具有较好的铸造性能，可用于金属型铸造。

电线载流量里的Cu,Al.是什么意思Cu是铜导体，AL是铝导体

Kirkendall 效应是指在置换式固溶体的扩散过程中，放置在原始界面上的标志物朝着低熔点元素的方向移动、移动速率与时间成抛物线关系。 Kirkendall 效应否定了置换式固溶体中扩散的「换位」机制，而证实了「空位」机制；系统中不同组元具有不同的分扩散系数，相对而言，低熔点组元扩散速度快，高熔点组元扩散速度慢，这种不等量的原子交换造成了 Kirkendall 效应。 晶体中结点并非完全被原子所占据，存在一定的空位，而且空位的数量随温度的升高而增加，在一定的温度 …

2025年1月16日 · Effects of the Formation of Al x Cu y Gradient Interfaces on Mechanical Property of Steel/Al Laminated Sheets by Introducing Cu Binding-Sheets
