FAQ'S
For more complex items, we should be able to respond within 24 or 48 hours. If you have any other specific question on any of our products or services, please contact us by email [email protected] or by telephone +86 592 5510319.
Q1: How strong is alumina ceramic?
>>> The hardness of alumina ceramics is nearly three times that of stainless steel. Alumina is a 9 on the Mohs scale. It cannot be scratched by anything with a lower hardness, so alumina can only be damaged by very few materials, including diamond. Compressive strength: This is the strength of alumina, which can reach 3,000 Mpa, a value that can exceed that of Zirconia.
Q2: Is alumina acid resistant?
>>> Alumina ceramics are widely used because of chemical corrosion resistance. Shifting atoms structure changes just enough to become chemically inert and thus unable to react rapidly with additional water molecules or atmospheric oxygen. This change in molecular structure is why aluminum oxide metal resists corrosion. Although alumina ceramics can resist many strong acids and organic acids, it can be corroded by HF due to silicon components in raw materials.
Q3: Is alumina an insulator or conductor?
>>> Alumina is commonly used as electrical insulator, particularly the higher purity grades which offer better resistivity.
Q4: How do you clean ceramic alumina?
>>> This is done by immersing the ceramic in a heated solvent (heating to increase activity) and then placing them inside an ultrasonic cleaner for at least 15 minutes. The solvent is then rinsed off using deionized or distilled water, which removes any loose contaminants from the surface.
Q5: How is alumina ceramic manufactured?
>>> Alumina components can be formed by a variety of manufacturing techniques such as dry pressing, cold isostatic pressing, injection molding, tape casting, and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining and a variety of other processes.
Q6: How long will it take for you to send me a quote?
>>> This depends totally on the complexity of your requirements. For simple items such as bars and rods, we can generally supply a quotation within 24 hours.
Q7: What is the disadvantage of alumina?
>>> Alumina shares several characteristics with other polycrystalline ceramic materials, such as moderate tensile and bending resistance and the brittle fracture behavior, which is the main disadvantage of the mechanical properties of alumina.
