In general, either cast iron or aluminum is used for the engine block.
This forms the majority of material used in a engine.
For other parts such as the crankshaft, valves, bearings, clutches, etc, a bewildering array of materials are used. Everything from brass and magnesium, to case-hardened steel and titanium even ceramics and composites are found in engines.
Cork is even used in some engine designs, though it has been largely phased out of all modern designs.

There is a lot of use for the electrical conductivity of metals. The main use would be the wires in your house, but they are also in you TV to transport the electricity from your wall plug to the main circuit board. Metal is used in everything that involves transporting electricity.
Iron is used !
Metals are not made, only mined, refined, and used. Metals are used for making things like kettles, airplanes, appliances, cars, bicycles, and stuff like that.
The concentrations of metals are typically higher in freshwater than in seawater because freshwater systems have less capacity to dilute or transport metals compared to seawater. In freshwater systems, metals can be sourced from natural weathering of rocks and human activities, and they accumulate as there is less water volume to disperse them. Conversely, in the vast volume of seawater, metals are more dispersed and diluted.
Gas, oil, machines, transport equipment, ores of rare metals.

There are no "nonmetallic metals", all metals are metallic by definition.
They used horses for transport.
