Key properties of the various materials used in machining

1. Metals

• aluminum:
  • Light weight: One of the lightest metals, allowing use in weight-sensitive industries such as aviation.
  • Corrosion resistance: Aluminum creates a protective oxygen layer that protects it from corrosion.
  • High machinability: Easy to machine and provides precise results.
  • High thermal and electrical conductivity: A good material for conducting heat and electricity.
• steel:
  • Strength and toughness: Steel is a very strong and durable material, suitable for use in mechanical industries and building construction.
  • High cutting capacity: Allows for precise machining, especially when it comes to versions such as mild steel or stainless steel.
  • Flexibility in processing: There are different types of steel that are suitable for a variety of processes, such as engraving, milling, and welding.
  • Corrosion resistance (in stainless steel): Maintains appearance and performance even in wet or corrosive environments.
• Titanium:
  • High strength: Titanium offers a high strength-to-weight ratio, meaning it is a very strong material relative to its weight.
  • Corrosion resistance: Resistant to acids, salt and several other chemicals.
  • Difficulty in machining: Titanium is difficult to machine because the material is hard and can cause rapid wear of tools.
  • Popular in the aviation and medical industries: thanks to its high resistance to high temperatures and hypoallergenic material (medical uses such as implants).
