Material of ceramic rod guide insert:
Usuaully the ceramic rod guide insert materials are alumina ceramic and zirconia ceramic,silicon carbide and so on.
alumina ceramic rod guide insert：
1.They have high mechanical strength. The flexural strength of sintered alumina ceramic products can reach 250MPa, and that of hot-pressed products can reach 500MPa. The strength can be maintained up to 900℃ at high temperatures.
2. High alumina ceramics have a high resistivity and excellent electrical insulation performance. The resistivity at room temperature is 1015Ω·cm, and the insulation strength is 15kV/mm.
3.High hardness, with a Mohs hardness of 9.
zirconia ceramic rod guide insert：
1.Zirconia ceramics have high strength and good toughness, and can be made into mechanical parts such as push rods, connecting rods, ceramic bearings, ceramic cylinder liners and piston caps.
2.Zirconia ceramic have high hardness, with a Mohs hardness of 8.5 to 9.1.
3.Insulating, free from the pollution of metals and electroplating, it is an ideal environmentally friendly material for the watch industry. Rich in color, extremely hard, beautiful and durable, non-damaging to the skin,and other products have an extraordinary texture and visual appeal, making them a popular choice for many electronic product cases.
silicon carbide ceramic rod guide insert：
1.Silicon carbide ceramic plate has excellent wear resistance and can be used continuously for more than 10 years. According to research tests, the wear resistance is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. It has extremely good wear resistance, reducing maintenance frequency and costs.
2.Its inner lining ceramic is of high strength, high hardness and very light weight. For instance, the Rockwell hardness of corundum ceramic is HRA90-98, which is much higher than that of wear-resistant steel and stainless steel, making it convenient for installation and replacement.
3.Its inner wall is smooth and does not clog powder. It is sintered at high temperature, with a dense structure. After grinding and deburring treatment, the surface is smooth.
