What Is A Mater Alloy?

Master alloy is a pre-alloyed material consisting of two or more metal elements, usually with one metal as the base and one or more high-content alloying elements. It is mainly used as an additive to adjust and optimize the composition and properties of the target alloy. It can also be used as a deoxidant, degasifier, and desulphurizing agent. A Master Alloy can be referred to as a “hardener”, “grain refiner”, or “modifier depending on the different applications. HM can provide high-quality magnesium-based master alloys, aluminum-based master alloys, copper-based master alloys, nickel-based master alloys, cobalt-based master alloys, iron-based master alloys, etc.

Why Are Master Alloys Added to Metal Melts?

  • Selective Composition Adjustment: The master alloys can modify the composition of the molten metal, allowing it to achieve a desired chemical specification.
  • Specific Performance Requirements: The master alloys can change the microstructure of a metal during casting and solidification to change its castability, surface finish, electrical conductivity, mechanical strength, or ductility.

Cobalt-Based Master Alloy

Cobalt-based master Alloys are made from cobalt and other metal elements (e.g., B, Ta, Mo, Nb, V, etc.) through advanced melting and casting processes, ensuring high-quality products with high purity, uniform organization, and stable chemical composition. These master alloy products can be used as reducing agents and additives in the metallurgy industry. HM can offer customized solutions for adjusting the composition ratio to meet specific requirements.

Cobalt-Based Master Alloy Features

  • Composition Uniformity: Precise melting process ensures uniform distribution of alloying elements and avoids compositional segregation.
  • Multifunctionality: The composition of the master alloy can be adjusted according to the requirements to meet the performance requirements of different alloys.
  • Various Forms: We can provide many forms according to the customer’s requirements, such as waffle ingot, cut waffle ingot, notch-bar, shot, etc.

Cobalt-Based Master Alloy Advanced Production Line

HM has advanced production lines with cutting-edge technology and precision engineering, ensuring consistent quality and performance in every batch. We can offer customization capabilities to tailor the composition, grain structure, and mechanical properties to meet every specific application demand. Our expert team will deliver a professional solution if you need enhanced strength, better corrosion resistance, or improved high-temperature performance.

  • Raw Materials Preparation: Select suitable metal raw materials according to the requirements, wash, dry, and crush them to ensure no impurities and reach the required particle size.
  • Accurate Dosing: Accurately weigh and pre-mix the raw materials according to the target alloy requirements.
  • Melting: Melting is carried out using equipment such as induction furnaces, electric arc furnaces, or resistance furnaces, with the addition of protective gases (e.g. argon) to prevent oxidization if necessary. Ensure uniform distribution of alloy components through mechanical or electromagnetic stirring.
  • Casting: The melted liquid alloy is poured into molds and cooled to form ingots.
  • Heat Treatment: Heat treatment of ingots eliminates compositional segregation and internal stresses and improves organization uniformity.
  • Processing and Molding: Cutting or crushing the ingot into the desired shape and size.

Cobalt-Based Master Alloy Applications

Cobalt-based master alloys are commonly used to manufacture alloy steels, corrosion-resistant materials, and high-temperature alloys. By adding the appropriate amount of cobalt-based master alloy, the content of alloying elements can be accurately adjusted to achieve the desired material properties. Cobalt-based master alloys mainly play the following roles:

  • Adjust the alloy’s composition
  • Improve the alloy’s properties
  • Refine the grain structure
  • Improve casting performance

Cobalt-Based Master Alloy Packaging

The Cobalt-based Master Alloy products are carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
