Material of ceramic pins:
Usuaully the ceramic pins materials are alumina ceramic and zirconia ceramic,silicon carbide ceramic,silicon nitride ceramic and so on.
Features of Alumina Ceramic pins：
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.
Features of zirconia ceramic pins：
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.
Application of ceramic pins:
1.Ultra-fine grinding equipment
2.Fine chemical industry
3.Electronic pastes, semiconductors, new energy
4.Nano-new materials, medical devices
5.Precision casting, structural ceramics, refractory materials
6.Electronic communications, sensitive ceramics, petrochemicals
7.Aerospace, mechanical manufacturing, optical fiber connectors, battery materials, etc.
They are an ideal type of wear-resistant ceramic rods.
