1. Automotive Industry

Metal parts are crucial in automotive systems:

• Engine: Crankshafts, rods, and pistons are key. Crankshafts need high - strength alloy steel. Rods require strength and toughness.

• Body: High - strength metals like hot - formed steel and aluminum alloy are used.

• Chassis: Suspension parts need elasticity and fatigue resistance. Wheels are usually aluminum alloy or high - strength steel.

2. Aerospace Field

• Aircraft: Aluminum alloy for the shell, titanium alloy for high - stress areas.

• Aeroengine: Blades use superalloy. Shafts and casings need strong, heat - and fatigue - resistant materials.

3. Electronic Equipment

• Phones and Computers: Metal in phones supports and dissipates heat. Computer heat sinks use heat - conductive metals.

• Component Packaging: Metal shells protect components from interference and damage.

4. Mechanical Manufacturing and Industrial Equipment

• Machine Tools: Key parts like the bed, column, and spindle are metal.

• Construction Machinery: Working and chassis parts have many metal parts with specific material requirements.
