Cast Composites


Technology for producing cast composites based on Fe-C alloys, i.e. cast iron and cast steel and Al-based alloys using reactive components.

We are working on this technology and will notify you when it is available.


Innerco offers licenses for technologies from the InnerComposites (IC) family used to produce local composite reinforcements in casting products based on iron alloys, i.e. cast steel and cast iron. They allow strengthening with hard ceramic particles of the casting in its top layer – 1IC or adapted to the wear profile zone – 2IC. Both technology variants together provide ultra-high abrasion resistance. We are in the final stages of developing the final member of the family, cast composites – 3IC, in which reinforcing particles are distributed throughout the casting capacity. This form of partnership is complemented by a full range of services related to the technology transfer process and the ability of the Innerco team to execute the full new product development cycle.

The common feature of the InnerComposites technology family is the formation of reinforcing particles directly in the liquid casting melt, thus ensuring the highest possible quality of the resulting metal matrix composite material. Our offer is addressed to global market leaders in the production and/or service of  machinery and equipment and vehicles, dedicated to 

the mining, cement, energy, metallurgical, rock and mineral processing, agricultural and chemical industries, supplying wear parts. The following is a general overview of the InnerComposites 1IC, 2IC and 3IC technology family.

The general characteristics of the
InnerComposites 3IC family are presented below.

3IC Composites

The use of 3IC i.e. cast composites products increasing the tensile strength, yield strength, hardness, and wear resistance in the whole volume of casting achieved owing to a hard ceramic phase addition.

We are working on this new technology to offer you classic casting grades with increased functionality.

We will gladly inform you about the 3IC technology implementation readiness.

Standard casting vs high-functionality MMC castings


We are constantly developing new technologies to produce metal matrix composites in castings. Our laboratories test and analyse new materials’ mechanical, functional, and physical properties. We have access to apparatus, machinery and devices that allow for their full characterisation. In addition, in advanced research techniques, Innerco closely cooperates with leading research units in Poland, ensuring the highest quality and efficiency of research.


1IC – Composite layers reinforced with WC particles are created using reactive liquid coatings in the traditional casting process. Thanks to its liquid consistency, you can use this solution to protect complex and complicated surfaces of your product. It is adapted to protect against medium and low abrasive wear and corrosion. For example, the application of the technology can be used for the protection of pipes, pump bodies, impellers in water or slurry environments, brake discs or parts for clinker coolers and for waste incineration. Reactive liquid foundry coatings can also be used in the standard protection of wear.
