Final answer:
Aircraft electrical junction boxes located in a fire zone are usually constructed of fire-resistant materials such as stainless steel or aluminum. These materials have high melting points and are able to withstand high temperatures, making them suitable for use in fire-prone areas. Additionally, the design and construction of these junction boxes often include features such as seals and gaskets to prevent the ingress of flames, smoke, and gases.
