MP159

MP159 COBALT NICKEL ALLOY

MP159 is a Nickel-Cobalt based multiphase alloy. This combination of properties enables ultra high strength, toughness, good ductility and excellent corrosion resistance.

MP159 has a high strength-to-weight ratio, making it suitable for use in aerospace and industrial applications where weight is a critical factor. Additionally, the alloy has excellent corrosion resistance, making it suitable for use in harsh environments such as the oil and gas industry.

MP159 alloy is typically produced through a process of vacuum induction melting (VIM) followed by vacuum arc re-melting (VAR) to ensure high purity and precise control of the alloy’s chemistry. This advanced manufacturing process helps to minimize the presence of non-metallic inclusions and unwanted residual elements, such as carbon, that can have a negative impact on the alloy’s mechanical properties and corrosion resistance.

VIM is a process where metal is melted in a vacuum, this process helps in removing impurities and gases, which is important in obtaining a high-purity alloy. VAR is a secondary melting process in which the VIM alloy is melted again in a vacuum, this process further refines the alloy, improves its homogeneity and removes any remaining impurities.

MP159 TECHNICAL INFORMATION

MP159 is a cobalt-nickel alloy that is known for its high strength and corrosion resistance. It is commonly used in aerospace applications, such as aircraft components, due to its high strength-to-weight ratio and excellent corrosion resistance. The alloy is also non-magnetic which makes it useful in electronic applications. The exact composition of the alloy is proprietary and not publicly available, but it is known to contain cobalt, nickel, chromium, molybdenum and tungsten. The alloy can be fabricated using a variety of methods, including machining, welding, and casting. Heat treatment can also be applied to further increase the alloy’s strength through precipitation hardening.

MP159 alloy, through work strengthening and aging treatment, can exhibit ultimate tensile strength levels in excess of 1830 MPa.

Work strengthening refers to the process of introducing a high density of dislocations into the alloy’s microstructure through cold working. This process can be used to increase the alloy’s strength, while maintaining its ductility.

Aging refers to the process of heat treating the alloy to form small, hard particles throughout the microstructure. This process, also known as precipitation hardening, can further increase the alloy’s strength, without significantly reducing its ductility.

When MP159 alloy is subjected to both work strengthening and aging treatments, it can exhibit very high levels of strength, making it suitable for use in aerospace and other high-performance applications that require high strength, corrosion resistance, and non-magnetic properties. It is important to note that the specific process and conditions that the alloy is subjected to will affect the final properties, and it’s important to consult with the manufacturer or a metallurgist to obtain the exact strength values.

It’s important to note that the above mentioned are some of the common applications of MP159 alloy and it can be used in other industries as well, depending on the specific properties required for the application. It’s always recommended to consult with the manufacturer or a metallurgist to determine if MP159 is the best alloy for your specific application.
