Cobalt vs Copper – What’s the Difference

Cobalt vs Copper

When it comes to metals, there are many options for industrial use. Two of the most popular materials are cobalt and copper. Both have their own unique properties and capabilities, making them suitable for a variety of applications. In this blog post, we’ll take a look at the differences between cobalt and copper in terms of price, properties, and composition.




The price difference between cobalt and copper can vary significantly depending on the market conditions. Generally speaking, cobalt is much more expensive than copper due to its rarity as a metal. On average, you can expect to pay around $25/kg for cobalt compared to just $2/kg for copper.


The properties of cobalt and copper vary greatly depending on their composition and form factor. As a pure element, cobalt has a higher melting point than copper (2723°C vs 1083°C). Additionally, cobalt has higher strength-to-weight ratios when compared to copper alloys. Finally, because of its low electrical resistance, cobalt is often used in high temperature electrical applications such as aircraft engines or turbines.


Cobalt is typically found in combination with other elements such as iron or nickel while copper is usually found as a pure element or combined with other metals like tin or zinc to form an alloy. The specific composition of each material depends on the application it is being used for but generally speaking, alloys will be stronger than pure elements due to their increased strength-to-weight ratio which makes them better suited for certain tasks. Additionally, certain alloys can also provide additional benefits such as corrosion resistance which may be important in certain applications.

Difference Between Cobalt and Copper

  • Cobalt is a complex, brittle metal that is silver-white. It is found in the Earth’s crust at an average concentration of 0.0058%.
  • Copper is a soft, malleable metal that is reddish-brown. It is found in the Earth’s crust at an average concentration of 0.0067%.
  • Cobalt is used in various applications, including batteries, magnets, pigments, and alloys.
  • Copper is used in various applications, including electrical wiring, plumbing, and coins.
  • Some key differences between cobalt and copper include their hardness, colour, and uses.




When deciding between cobalt and copper for your next project, consider all the factors involved—cost, strength, durability, and ease of use—to determine which one best suits your needs. Both materials have advantages and disadvantages; however, with proper care and maintenance, they can last for years in any industrial application. Ultimately the choice comes down to your personal preference based on what your project demands from each material.
