Hardness

Dictionary

Impact resistance describes the strength of a material under sudden loads, such as hard blows or impacts. In various tests, such as the Charpy or Izod test, the impact resistance is determined by testing the material for sudden loads until it breaks or tears. High impact resistance is particularly important for applications with high dynamic loads. This is achieved by certain plastics or alloy steels, for example.

Similar to abrasion, wear is a gradual loss of material on the surface of components. It can be caused by several factors, including friction, abrasion or corrosion. Wear resistance is primarily influenced by material hardness, surface condition and lubrication. The choice of the right tools, lubricants and coolants is therefore essential, especially in manufacturing, in order to minimize the effects of wear and thereby extend the service life of components, tools and machines.

Dictionary

Corrosion resistance is the ability of a material to withstand all influences, including chemical or electrochemical attacks. Materials with high corrosion resistance can withstand even aggressive influences such as salt or acids and are therefore not only suitable for a wide range of applications, but also retain their full functionality and strength. In part, high corrosion resistance is caused by the natural properties, but it can also be significantly improved by numerous coatings or other surface treatments afterwards.

Dictionary

Stiffness describes the property that a material can resist permanent deformation even under load. This is determined, for example, by the modulus of elasticity or G-modulus. Stiffness is an important indicator of the stability and functionality of components, as materials with a high stiffness retain their original shape even under heavy loads.

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.
