Q. What type of metal are seat belt buckle made of?

Answer

Weaved polyester, or a combination of nylon and polyester, is used to create seatbelts rather than metal. For these reasons, it is a great choice for belt buckles, jewelry, and even medical applications inside the body. The tongue, which is attached to the webbing, is held in place and released by the buckle of a seat belt. The tongue is held securely in place by the buckle, and the seat belt can be quickly and easily secured and loosened with minimal effort. Organic polymers, such as those found in plastics, are pulled into fibers, or strands, to create carbon fiber.
