Appropriate Materials for Investment Casting Applications

The sky's the limit for investment casting applications when combined with the unique properties of stainless steel, cobalt alloys and nickel-based alloys. These materials bring a range of advantages to the table, making them invaluable for various applications of investment casting.

Stainless Steel

Stainless steel stands as a highly versatile material that has revolutionized the world of investment casting. It is an invaluable asset in applications ranging from aerospace to power generation because of its:

  • Corrosion resistance
  • Strength and toughness
  • Temperature resistance
  • Versatility
  • Aesthetic appeal

Cobal Alloys

Cobalt alloys have found a use in a broad array of investment casting applications, thanks to their:

  • High-temperature strength
  • Wear and corrosion resistance
  • High strength-to-weight ratio

Cobalt alloys lend themselves well to the precise and complex geometries produced by investment casting. These materials' excellent castability and flow characteristics enable the production of detailed, near-net-shape parts with intricate features, thin walls and fine details.

Nickel-Based Alloys

Nickel-based alloys are the material of choice for a variety of investment casting applications due to their:

  • High-temperature strength
  • Corrosion resistance
  • Wear resistance
  • Cryogenic stability
  • Fatigue and creep resistance

The Wide World of
Investment Casting Applications

The applications of investment casting are nearly endless. If a part requires complex geometries, a near-net shape and superior surface quality, it's likely an application for investment casting.

We'll start with aerospace investment casting and aviation investment casting; then we'll look at other critical applications for this versatile process.
