Refractory metals are a group of metallic elements known for their high melting points, exceptional strength, and resistance to wear and corrosion. Common examples include tungsten, molybdenum, and tantalum. These properties make them ideal for use in extreme environments, such as aerospace, nuclear reactors, and high-temperature applications. Due to their durability, refractory metals are often used in manufacturing tools, electrical contacts, and components in various industries. Their ability to withstand intense heat and stress allows them to maintain performance where other materials might fail, making them essential in advanced engineering and technology.
