Technical ceramic is harder than metal and nearly as hard as a diamond. An example from the consumer technology is an injector for capsule coffee machines. The special cone tips pierce the multilayer film of the capsules with high precision and maximum hygiene. In this way the coffee powder can develop its aroma in the water optimally. The use of advanced ceramics ensures lasting sharpness of the tips to handle the high strain in daily work.
Alumina - versatile, durable and competitive
Bosch alumina is used in many applications. Hardly any other ceramic material combines broad applicability with a competitive price. Alumina gives the injector particularly good abrasion resistance. Other positive characteristics are high rigidity, chemical resistance and temperature stability.
