Product details
Graphite has very good wear resistance. Graphite has ultra-high hardness and toughness, so it is not susceptible to wear. In addition, graphite has high density, low friction coefficient and good anti-friction properties, which allows it to withstand high-intensity mechanical loads. , can lubricate within 2000 degrees Celsius and at high sliding speeds. Many equipment that transports corrosive media widely use graphite materials to make piston rings, sealing rings and bearings, etc. In the mechanical industry, we usually use graphite rods as lubricants, because if we simply use lubricating oil, it cannot be used under conditions such as high speed and high temperature, so we need to use graphite rods because it can glide quickly at higher temperatures. . Generally, equipment that transports corrosive media can use a variety of graphite rods as piston cups. According to the material, graphite rods can be divided into impregnated graphite rods, also known as medium-coarse material graphite rods, molded graphite rods, and isostatically pressed graphite rods. Graphite rods of different materials can be customized according to needs and usage scenarios. Our company is the source factory and supports global shipments.
Product features
High hardness graphite rods have the following characteristics:
1.High hardness and high strength:
It has excellent anti-wear properties. It is not prone to scratches, wear or deformation when in contact with other objects, friction or under certain pressure. It can maintain the smoothness and dimensional accuracy of the surface for a long time, which makes it suitable for applications where high durability is required. It has important application value in wear-resistant situations, such as wear-resistant parts and mold materials in mechanical parts.
It has high strength and can withstand large external forces without breaking or being damaged. It can be used in some structural parts that have high requirements on material strength. For example, it can be used to manufacture some structural parts in the aerospace field.
2.Good electrical conductivity:
The main component of graphite rods is carbon. There are a large number of free electrons between carbon atoms. These free electrons can move freely under the action of an electric field, thereby forming an electric current, making it have good electrical conductivity. The conductivity of high-hardness graphite rods makes them widely used in the electrical field, such as manufacturing electrodes, brushes, conductive connectors, etc.
3.High temperature resistance:
The melting point of graphite is very high, generally above 3000°C, so high-hardness graphite rods can maintain stable performance in high-temperature environments and are not prone to softening, deformation or melting.
Its strength may also increase at high temperatures, which makes it suitable for high-temperature working environments such as electric heating bodies of high-temperature vacuum furnaces and linings of metallurgical furnaces.
4.Chemical stability:
At normal temperature, high-hardness graphite rods have good chemical stability and are resistant to acid, alkali and organic solvent corrosion. This allows it to be used as a catalyst carrier, anti-corrosion coating material, etc. in the chemical industry, and can maintain stable performance in complex chemical environments.
5.Good thermal conductivity:
High-hardness graphite rods have high thermal conductivity and can transfer heat quickly. This characteristic makes them have application potential in heat exchanger components, heat dissipation materials, etc. For example, in electronic equipment, it can be used to quickly conduct heat generated by electronic components to ensure the normal operation of the equipment.

Quality inspection and packaging
Quality inspection
Conduct quality inspection on the finished high-hardness graphite rods, including inspection of hardness, density, strength, conductivity and other performance indicators, as well as inspection of appearance dimensions, surface quality and other aspects. Only graphite rods that meet quality standards can be packaged and shipped from the factory.
Packaging and storage
Qualified graphite rods are usually packaged in plastic film, cartons or wooden boxes to prevent the graphite rods from being damaged or contaminated during transportation and storage. At the same time, graphite rods should be stored in a dry, ventilated, and cool place, away from direct sunlight and high temperature environments.
FAQ
What is the high temperature resistance of graphite products?
Graphite has excellent high temperature resistance. Ordinary graphite products can work stably at high temperatures of around 2000°C, while some special high-purity graphite products can even withstand higher temperatures.
What is the chemical stability of graphite?
Graphite has good stability to most chemicals. At normal temperature, it does not react with acids, alkalis, salts, etc. However, at high temperatures, oxidation reactions may occur when in contact with strong oxidants.
Does graphite have good thermal conductivity?
Graphite has very good thermal conductivity and is a good thermal conductive material. It has a higher thermal conductivity than many metals, allowing it to transfer heat quickly and evenly.
How to judge the quality of graphite products?
The quality of graphite products can be judged from the following aspects: first, look at the appearance, the surface should be smooth, without cracks, and without impurities; secondly, check the density, graphite products with high density usually have better quality; you can also test their electrical conductivity, thermal conductivity, etc. indicators to assess quality.
