Which is better, alumina or steatite?

Which is better, alumina or steatite?

We will provide proposals and consultations on all aspects, including price and delivery time.

[For those who think, "Ceramics are expensive because they are ceramics!"] *Characteristics of two types of ceramic materials: Alumina: High mechanical strength with resistance to corrosion and wear, but more expensive than steatite (about 1.5 times). Steatite: Good insulation properties and inexpensive. Commonly used in electrical and heating components. [Common examples] If a part designed for insulation can be sufficiently made from steatite, making it from alumina will naturally increase the cost. If a part is made from steatite for wear resistance simply because it is cheaper, it will wear out quickly, resulting in the need to produce more parts, ultimately increasing costs. *Choosing the right ceramic material based on application is the key to purchasing at a lower cost.
