Alumina ceramic purity 99.7% corundum tube for high temperature tube furnace
1. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
2. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
3. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

Alumina ceramics are the most versatile of the advanced technical ceramics.stronger than the traditional ceramics chemically inert-excellent corrosion resistance outstanding electrical insulators,even at very high temperatures extremely hard-excellent abrasion resistance are almost unaltered at 1000°C,useable up to 1700°.All alumina bodies possess very good mechanical properties such as hardness and compressive strength. They also hold up well under harsh conditions such as acid corrosion,high wear areas,and sliding abrasion. They also possess very good electrical insulation properties and have very specific thermal conductive and thermal expansion rates.
Q: Is it possible to provide samples?
A: We can supply 1-2 samples, but we do not bear the shipping cost of the samples.
Q: How long is the delivery time usually?
A: Product delivery is subject to order quantity and processing requirements, and different product delivery times are inconsistent. Generally speaking, the delivery time of 1-2 common product samples is about 35 days.
Q: Which payment methods are supported?
A: T/T; credit card. Currently our company supports these two payment methods.
Q: What is the shipping date? How long can I ship?
A1: Shipped within 72 hours after the balance is settled
A2: After the production of the product is completed and passed the internal inspection of the company, we will send the finished product image to the customer for confirmation. After the balance is settled, all the products will be sent to the customer's designated delivery location.
