alumina ceramic components,
high temperature machinable ceramic
White ceramic tube / insulator with 95% alumina as raw material
Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc.

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?
