Applicable scenarios for screws of different materials:
Carbon steel: General applications (construction, furniture), low cost but prone to rust.
Stainless steel: Humid environments (kitchen, outdoor), corrosion resistant.
Copper: Conductive applications (electrical appliances), rust resistant but low strength.
Titanium: High strength and lightweight (aerospace), corrosion resistant but expensive.
Nylon: Insulating and corrosion resistant (electronics, chemical industry), non-magnetic.
