Corrosion

Dictionary

Weather resistance refers to the ability of a material or product to withstand the effects of weather conditions such as rain, snow, sun, wind and temperature fluctuations without losing functionality, aesthetics or structural integrity. In the manufacturing industry, weather resistance is critical to the longevity and reliability of products that are used outdoors, such as building components, vehicle parts or outdoor equipment. By improving weather resistance, companies can extend the life of their products, reduce maintenance costs and increase customer satisfaction. Techniques to increase weather resistance include the selection of suitable materials, the use of coatings and the application of protective treatments.

Dictionary

Impact strength describes the ability of a material to withstand impact loads or sudden forces without breaking or permanently deforming. It is usually determined using test methods such as the Charpy or Izod impact test, in which the energy that a material absorbs at break is measured. In the manufacturing industry, impact strength is decisive for the selection of materials in safety-relevant applications, such as vehicle components or machine components that are exposed to high mechanical loads. High impact strength ensures the reliability and durability of products under changing load conditions, which helps to reduce failures and increase safety.

Dictionary

Surface roughness measures the unevenness and texture of a surface at the smallest level. It is mainly measured by the height differences on the surface and is given in micrometers (µm). The mechanical properties strongly depend on the surface roughness as it influences friction, wear and functionality. Therefore, choosing the right surface roughness is also important for manufacturing processes such as CNC machining. The roughness is often improved by various finishing processes such as grinding and polishing.

Dictionary

Magnetizability describes the ability of a material to develop its own magnetic properties under the influence of an external magnetic field. Materials such as iron, nickel and cobalt, some of which retain their magnetic properties even after the external magnetic field has been removed, are particularly suitable for this process. The magnetizability of a material is characterized by its permeability. High magnetizability makes materials particularly interesting for electrical engineering or magnetic bearings.

Dictionary

Fatigue strength is the ability of a material to withstand repeated loading during operation without failure. It is calculated from the fatigue, the material properties and the real operating conditions. The fatigue strength can be predicted in advance using various tests and simulations. High fatigue strength has a positive effect on reliability and durability, which is particularly important in the automotive and aviation sectors as well as in mechanical engineering.
