Cobalt-chromium (or cobalt-chrome) is a metal alloy that has gained prominence in a variety of industrial applications, particularly in additive manufacturing. With its unique combination of strength and durability, cobalt-chrome is ideal for creating parts that require high precision and strength under demanding conditions, such as medical and dental components. This alloy stands out not only for its mechanical properties but also for its ability to be molded into complex shapes using 3D printing, opening up new possibilities in the design and manufacture of customized parts. In this guide, we’ll explore the properties of cobalt chromium, its advantages in 3D printing, and the main applications and manufacturers of this material on the market.

Characteristics of the Material

As its name suggests, this metal alloy (CoCr) consists mainly of the chemical elements chromium and cobalt. It also contains a small proportion of other chemical elements, such as molybdenum, tungsten and nickel. It is a non-magnetic alloy obtained by advanced metallurgical processes involving the fusion of cobalt and chromium with other elements to enhance its mechanical properties and strength. One of the most common methods of obtaining them is electric furnace melting, in which these metals are melted at high temperatures in induction or electric arc furnaces. In some cases, once the liquid alloy has been obtained, it can be subjected to a forging process, which involves heating and molding the material by applying pressure.

This material is characterized by its strength and durability

However, when required in the form of metal powder for 3D printing applications, cobalt-chrome can also be obtained by sputtering. In this process, the alloy is converted into fine particles using atomization or sputtering techniques, enabling it to be used in additive manufacturing technologies based on powder beds. These techniques make it possible to create complex parts from metal powder, offering greater flexibility in the design and manufacture of high-precision components. Among cobalt-chrome’s most outstanding characteristics are:
