Customized Long Using Time Electrical Isolation Alumina Ceramic Ignition Tube
Material: Alumina(Al2O3)
There are both coarse and fine-grained varieties. Examples of applications for aluminum oxide Al2O3 advanced ceramics are heavy-duty forming tools, substrates and resistor cores in the electronics industry, tiles for wear protection and ballistics, thread guides in textile engineering, seal and regulator discs for water taps and valves, heat-sinks for lighting systems, protection tubes in thermal processes or catalyst carriers for the chemicals industry.
Advantages of ceramic tube
• High hardness
• Wear & abrasion resistant
• High compressive strength
• High mechanical Strength
• Resists strong acid and alkali attack at high temperatures
• Excellent electrical insulation properties
• Decent thermal conductivity

Answer: With the development more than 20 years, now we have 6 business division and we are supplying Quartz Glass (Tube,Rod,Plate and customized parts), optical glass and cuvette, and also various precise ceramics, porous ceramics and refractoryceramics. We have the full processing line for ceramic thick film resistors, far infrared ceramic glass heating panel, quartztube/ceramic plate ozone generator and porous metal fiber felt. For all the products, we can design and customize according to the clients’ demand.
2: Before mass order, can you offer samples? How will you charge for them?
Answer: We are willing to offer samples to lower your purchasing risk. Generally, if from inventory, we can deliver out within 3days, however if need processing, we can deliver out within 15 days. For some difficult items, the delivery time will be decided by its grade of difficulty. For some low value items, we can offer free sample, however we would like you to afford the freight cost. For customized products, we need to charge the developing cost.
3: What test report or certificate can you offer? What achievements have you made in research and development?
Answer: Till the end of 2021, we have passed many ROHS, CE, MSDS tests and also the ISO9001 authentication. We have 8 registered trademark and 25 patents. Also we won the title of China High-tech Enterprise and Jiangsu Private Science and Technology Enterprises.
4: Do you have any agent in our area? Can you export your products directly?
Answer: Till the end of 2021, we haven’t authorized any company or person as our regional agent. From 2008, we have the export qualification and professional export team, and till the end of 2021, we have exporting our products to more than 103 countries and regions, and our clients can contact us and purchase our products or service directly.
5: If the quality can not meet the requirement or any loss during the freight, how should we do?
Answer: We have strict QC test and professional QC team. We are always offering qualified products. If anything goes wrong, the quality can not meet requirement on the contract, we will reproduce the qualified products or refund the payment. We have the professional packing team and will pack the product in safe package for long distance delivery. If any loss during the freight, we hope you can assistant us to claim from the logistics company and we will arrange the replacement accordingly.
