FAQ
Q1. What is the difference between ceramic and alumina?
A1: Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
Q2. What is alumina ceramic used for?
A2: Because of their excellent chemical stability, alumina ceramics are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
Q3.Is alumina ceramic hard?
A3: Alumina is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
Q4. Incoterm: FOB, CFR, CIF;
Q5. Delivery Cost: It is determinated by the destination port;
Q6. Payment Term: PayPal; T/T;
Q7. Shipment: by sea, by air, by courier, by post, etc.
