2. Good plasticity and toughness: Despite QBE190.1 Beryllium bronze has high strength and high hardness, and it still retains good plasticity and toughness. This means that it retains its shape under pressure or deformation, and has the ability to resist breakage and breakage. As a result, the alloy performs well in applications that need to withstand deformation or extrusion stresses.
3. Fatigue resistance: QBE190.1 Beryllium bronze has excellent fatigue resistance, i.e., it retains its integrity and performance after multiple cycles of loading. This makes it ideal for manufacturing parts that require frequent vibrations, shocks, and repeated loading.
4. Abrasion resistance: Due to its high hardness and fatigue resistance, QBE190.1 Beryllium bronze exhibits good wear resistance and can resist wear and friction when in contact with other metals. As a result, the alloy is often chosen as the material in applications that require high wear resistance.
Overall, qbe190.1. Beryllium bronze has the main characteristics of high strength, high hardness, good plasticity and toughness, excellent fatigue resistance and wear resistance. These properties make it excellent for manufacturing components that are subjected to high loads and shock loads, such as in the aerospace, automotive, and construction machinery sectors.
