Ceramic tubes are crafted from premium-grade materials like alumina (Al2O3) , renowned for their exceptional thermal and mechanical performance. Through meticulous processes-such as shaping, high-temperature sintering, and precision finishing-these tubes are engineered to exact specifications. Available in diverse sizes, they cater to specialized industrial requirements. Their outstanding properties, including high thermal conductivity, minimal thermal expansion, and remarkable durability, make them ideal for demanding applications, from furnace components to advanced electronics.
Sintering temperature of our 99% alumina electric ceramic tube is 1800 ° C, the extrusion molding process, burning forming. Total length of 2000 mm, the effective length of about 2000 mm.
We produce 99% alumina electric ceramic specifications are as follows:
1, ceramic rods, 1 to 30 mm in diameter, length less than 1000 mm;
2, ceramic tube, 1-120 mm outside diameter, length is 2000 mm, Pore number can be customized, such as 2 small 1 big hole, the eccentric hole features such as pore diameter are customizable, andmost have routine with specifications Mould, without user to pay the mould cost.
