Strength

Its strength and flexibility make it ideal for use in automotive, aerospace, and construction applications
  • Cost-effectiveness: Generally cheaper than other metals such as aluminum or copper, so it costs less.
  • High strength
  • Plasticity: Can be machined into various shapes and sizes through methods such as casting, forging and rolling.
  • Magnetic: Making motors, generators and other electromagnetic devices.
  • Recyclability

Weakness

  • Rusting: Susceptible to rusting in wet environments and requires appropriate corrosion protection.
  • Heavy Weight: Denser and heavier than other light metals.
  • Thermal Expansion: Higher coefficient of thermal expansion, which can cause dimensional changes when the temperature changes.
  • Brittleness: Pure iron is brittle and usually requires alloying to improve its toughness.

Application

  • Construction: Building structures such as beams, columns, and frames.
  • Machinery: Make various machine parts and equipment such as engines, pumps, and machine tools.
  • Automotive: Make car bodies, engines, and other parts.
  • Consumer Goods: Make bed frames, chairs, and other furniture.
