Strontium (Sr) is a soft, silvery-white alkaline earth metal that is highly reactive and does not occur naturally in pure form. It is primarily used in alloys, pyrotechnic applications, and specialized ceramics rather than as a standalone structural material, owing to its low strength and high reactivity. The metal is valued in the aerospace, pyrotechnics, and medical device industries for its ability to improve alloy properties and its biological compatibility in certain biomedical formulations.
