Yellow Advanced High Precision 95%-99.5% Alumina Ceramic Seal Ring
Feature:
1) High hardness.
2) High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is
widely used in areas where resistance to high temperatures is essential.
3) Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
4) High electrical resistivity : Alumina is an electrically insulating material.
5)High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and
alkaline solutions.
6) Good chemical stability of alumina leads to high corrosion resistance.

Company Introduction:
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.
