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.
