Metals are a category of chemical elements that are characterized by their high electrical conductivity, malleability, and ductility. They are widely used in various industries such as construction, transportation, electronics, and manufacturing due to their unique physical and chemical properties. Research in the field of metals focuses on understanding their metallurgical properties, developing new alloys with specific characteristics, and improving production processes to enhance their performance and durability. Additionally, research in metals also explores their environmental impact, recycling methods, and ways to mitigate any potential negative effects on human health and the environment.
