Nickel-Based Metal Castings

At Aero Metals we carry a wide variety of commonly used nickel based metal casting alloys for our customers metal casting project needs. In many cases wrought components have equivalent casting alloy specification and can easily be converted without derogation. When converting from a previously designed wrought component to a nickel-based casting, the nickel based metal casting design can usually be made to improve productivity and reduce the total cost of your nickel based alloy casting project.

Nickel-Based Alloys for Metal Investment Casting

Alloy choice is a very important aspect of part design. Choosing the right nickel-based alloy is dependent on several factors, including the environment the nickel based castings will be exposed to while in service. Furthermore, if the nickel based alloy castings are going to be used in conjunction with a wrought component (i.e. welding two components together) it is important to have a preliminary discussion with our metallurgist to ensure you choose the appropriate chemistry and material properties suitable for your application.

Nickel-based alloys are known for their oxidation and corrosion resistant properties in harsh environments and high-temperature applications. In addition, within today’s marketplace there are several trademark names for nickel based alloys that ASTM specifications make accessible to everyone, these include:

• Monel® - Monel® is a nickel based alloy that is primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Monel® is stronger than pure nickel, and its alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be casted and fabricated readily by hot- and cold-working, post-cast machining, and welding.
• Hastalloy® - Hastalloy® is a nickel based metal casting alloy, and it is highly resistant to corrosion. The inclusion of molybdenum makes Hastalloy® harder, stronger at high temperatures, and makes it great for welding applications. These nickel based alloy castings are easily fabricated and formed. They have good ductility and can be forged and cold worked.
• Inconel® - Inconel® nickel based alloy castings are oxidation- and corrosion-resistant materials well suited for service in extreme environments where they are often subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel® retains strength over a wide temperature range, and is attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. This nickel based alloy’s high temperature strength is developed by solid solution strengthening or precipitation hardening.
