What is a Metal Materials?

Metal materials, widely used in various industries, are materials made of metals or containing them as significant components. Metals such as iron, aluminum, copper, steel, gold, silver, lead, and zinc can be cited as examples. In the field of model rocketry, metals are preferred to ensure the structural integrity of rockets and for critical components such as motor assembly. For instance, aluminum and steel are commonly used metals in the construction of rocket bodies. These metals provide resistance to the airflow for rockets with their high strength and durability. Additionally, they are used to strengthen motor attachment parts and the outer surface of the rocket. The lightness of aluminum reduces the total weight of the rocket, while the high strength of steel enhances the safety of the rocket. Conductive metals such as copper and gold can be used in the assembly of electronic components, enabling the effective operation of telemetry and control systems. However, the weight and tendency to corrosion of metals may lead to the preference of alternative materials in some cases. The selection of metal materials for model rocketry depends on design requirements, performance goals, and cost factors.
