yes plastic is a non metal . because it cannot be make into wires and plastic can break also. Plastic doesn’t conduct electricity and does not possess any of the physical properties of metals like ductility, malleability, lustre, etc.!

How does replacing of metal parts with plastic parts in aircraft help?

Answer: Eliminates the need to weld, grind, add dents/scratch resistance aspects and/or noise dampening to the material2. Plastics significantly reduce the weight of materials as compared to when metals are used, thereby reducing shipping costs and improving the end-user’s physical ease when utilizing the product.
