It starts with aluminium oxide and ends with the perfect ball. In between are decades of experience and innovation. The dimensions: 0.2 to 60 mm. The materials: sapphire, ruby, ceramic and more. The shape: perfectly precise, perfectly round.More ...Weniger ...
Sapphire (Al2O3) Very hard material, completely transparent, monocrystalline aluminium oxide, synthetically produced, inert against aggressive media such as acids and alkali.
Ruby (99% Al2O3 + 1% Cr2O3) The red version of sapphire, contains small pieces of chromium oxide. The most commonly used material for styli.
Aluminium oxide (Al2O3) Simply referred to as ceramic, this is the most commonly used high-performance ceramic material. Outstanding hardness, excellent insulator. Purity improves its mechanical properties, which is why Saphirwerk mainly uses ultra-pure Al2O3.
Zirconium oxide (95% ZrO2 +5% Y2O3) High fracture toughness is achieved through stabilisation. Similar heat expansion to steel. Good for bend-resistant rods and balls for ball bearings.
Silicon nitride (>90% Si3N4) Very high fracture toughness, small elastic modulus and low coefficient of thermal expansion, exceptionally wear resistant. Suitable for ball bearings and other uses.
Hard metal (94% WC + 6% Co) A composite material characterised by superior hardness and wear resistance. Distinguished by its high density. Primarily used for cutting tools.
Made of the hardest materials, for highly sensitive applications, in a variety of shapes and sizes. Used by the best in the world. For finely tuned measurement technology.More ...Weniger ...
