5 FAQs of 99.5 % Corundum Ceramic Insulator / Alumina Tube For Electrical Furnace, Industrial Corundum 99% Alumina Tube Ceramic Tube

99.5% Alumina Tubes: Your Furnace Insulation Questions Answered

What are these alumina tubes made of?
These tubes are made from nearly pure aluminum oxide. We call it alumina. The purity is either 99% or 99.5%. This high purity makes them very strong. They resist heat extremely well.

How hot can these tubes get?
These tubes handle very high temperatures. The 99% grade works up to about 1650°C (3000°F). The 99.5% grade handles even more heat, up to 1750°C (3180°F). They stay stable and won’t melt or warp easily.

Where are these alumina tubes used?
Their main job is inside electrical furnaces. They act as insulators. They hold heating elements. They form protective sheaths for thermocouples. They create tubes for samples. Industries like labs, ceramics, metallurgy, and semiconductors use them constantly.

Is 99.5% purity much better than 99%?
Yes. The extra 0.5% purity matters. The 99.5% tube handles higher temperatures. It resists chemical attack better. It has higher electrical insulation. It lasts longer under tough conditions. It costs more, but the performance gain is real.

Can I get these tubes in custom sizes?
Yes. Standard sizes exist. Many manufacturers offer custom orders. Tell them the outside diameter, inside diameter, and length you need. They can usually make it. Check their capabilities first.
