Aluminum (CAS 7429-90-5)

Aluminum, represented by the symbol Al and with a CAS number of 7429-90-5, is a lightweight, silvery-white metal known for its low density and high strength-to-weight ratio. As the most abundant metal in the Earth′s crust, aluminum is extensively used in a variety of applications beyond the scope of medical and pharmaceutical fields. In scientific research, aluminum is particularly valued for its excellent conductivity of heat and electricity, as well as its resistance to corrosion, which is enhanced by the metal′s ability to form a protective oxide layer. This makes it an ideal material for use in experiments involving extreme conditions. Aluminum is also pivotal in materials science, especially in the study of metallurgy where it is often alloyed with other metals to improve its properties for specific applications, such as increased strength or thermal conductivity. Furthermore, aluminum′s reflective nature is exploited in optical research, where it is used to coat telescope mirrors and other optical instruments. In environmental science, studies often focus on the impact of aluminum on ecosystems, particularly in the context of acid rain where aluminum released into the soil can affect plant growth. The metal′s versatility and unique properties make it a subject of interest in fields ranging from aerospace engineering to sustainable materials development.
