Wear Resistance Alumina Ceramic Tubes With Good Insulation Performance
Ceramic furnace tubes, thermocouple protection tubes and insulating rods produced by Mingrui are made of alumina ceramic (Al2O3 > 99%). Alumina ceramic possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. The max. using termperature of these tubes & rods can be up to 1800 °C. They are an excellent choice in furnace and temperature measurement whenever safety and stability are required.
The size of the high temperature ceramic tubes & rods can be customized according to customer's requirement:
*Good thermal conductivity
*Good strength and hardness
*Good resistance to wear and corrosion
*Temperature resistance up to 1800°C

Dongguan Ming Rui Ceramic Technology Co., LTD., a professional
manufacturer of machined ceramic parts, has 10 senior engineers and
lots of technicians. We produce strengthened structure zirconia
ceramic bar, ceramic tube, ceramic shaft, ceramic plate, ceramic
sleeve, ceramic valve, ceramic plunger and ceramic arm. The
products are applicable to instruments, medical instruments, clocks
and electronic products, mills, energy and power, machine and
metals, autocar and military and some other high-end areas.
In cooperation with Tsinghua University, we've achieved great
successes in particular requirements. With our professional
knowledge and business experience in machined ceramic parts,
low-budget and high-performance new ceramic products are made of
high–quality raw materials. The value of our ceramic products is
greatly increased due to the composite technology and precise
processing.
Our high efficiency machined ceramic parts, perfect service and
good reputation roots in our professional machined ceramic
technology, continuous innovation, great sincerity and our pursuit
for sustainable development. We have a unique technnology called
“mirror polishing” that has improved the brightness, color,
smoothness of our ceramic parts.
