    Material Overview

    Finished products can be manufactured out of the following materials:

    • CARODUR®
    • CARO®444

    Due to the membership within the Wieland-Group a broad range of materials can be offered.


    We manufacture finished parts and solid sliding elements in turned and milled design, as slide bearings, stop discs, and precision parts made of high-strength copper alloys, as well as rolling bearings. The products are made in various designs and adjusted according to customer requirements.

    CARODUR® (CuNiSi)

    This alloy is a beryllium-free, environment-friendly and thermosetting alloy based on CuNiSi.

    CARODUR 1 is one of the basic materials for slide bearings. This material is characterized by an excellent cold- and warm formability against stress corrosion cracking. As such, CARODUR brings following advantages:

    • High rigidity and hardness
    • Excellent electrical conductivity
    • High abrasion resistance
    • Good heat conductivity
    • High endurance limit
