What is the Difference Between Beryllium and Aluminium?
🆚 Go to Comparative Table 🆚Beryllium and aluminum are two distinct metallic elements with different physical and chemical properties. Here are the key differences between them:
- Density: Beryllium has a density of 1.85 g/cc (0.067 lb/cu.in.), while aluminum's density is approximately 45% higher at 2.7 g/cc (0.097 lb/cu.in.).
- Hardness: Beryllium is a harder and more brittle material compared to aluminum.
- Chemical Properties: Beryllium and aluminum have different chemical properties, with beryllium being a group II element and aluminum being a group XIII element.
- Periodic Table Position: Beryllium is located in group II and period 2 of the periodic table, while aluminum is in group XIII and period 3.
- Natural Occurrence: Beryllium naturally occurs in minerals such as Bertrandite, Beryl, Chrysoberyl, and Phenakite, with an abundance of about 4-6 ppm in Earth's surface. Aluminum is the second most abundant metallic element in Earth's crust and has only one naturally occurring isotope, aluminum-27.
- Industrial Applications: Beryllium is primarily used in the aerospace industry due to its lightweight and high-strength properties. Aluminum is widely used in various industrial applications, being the second-largest metallic element used globally.
In some cases, beryllium and aluminum can be combined to form alloys, such as aluminum-beryllium alloys, which have specific properties that can be beneficial in certain applications.
