Application Fields

01 Photovoltaics and Semiconductors

The "photovoltaic revolution" with carbon neutrality goals

Recently, countries have raised carbon emission reduction and renewable energy to an important strategic height, and 

the proposed planning goals have given photovoltaic medium and long-term growth potential, opening the golden 

development cycle of the industry in the next ten years.

High-purity graphite for the semiconductor industry

With the vigorous development of various terminal applications such as 5G communications, new energy vehicles, 

the Internet of Things, smartphones, and consumer electronics, the semiconductor market continues to grow.

02 EDM

Graphite—a more ideal electrode material

Compared with the traditional electrode material copper, graphite is a more ideal electrode material due to its advantages

 such as low electrode consumption, fast processing speed, good machinability, light specific gravity, high temperature 

resistance, bondability, and easy surface treatment.

EDM application

Automotive molds, home appliance molds, shoe molds, etc., mobile phone, telephone molds, mesh molds, home appliance molds, 

automotive interior molds, 0A molds, IC packaging molds, precision LOGO logos, connector electrodes, etc.

Our materials are suitable for all kinds of molds from large to small, from fine to ultra-micro… 

03 Hydrogen fuel cell

Application of graphite materials in "clean energy"

Compared with traditional energy, hydrogen energy is clean and environmentally friendly, with high energy 

density, and is regarded as a clean energy. As one of the main application fields of hydrogen energy, hydrogen 

fuel cells obtain electricity through the oxidation-reduction reaction of hydrogen in the stack to drive vehicles. 

The reaction process only generates water, achieving zero discharge. Therefore, hydrogen fuel cells are 

considered as one of the ideal power sources to meet future energy and environmental requirements due 

to their high energy conversion rate, low emissions, and high energy and power density.

Finding high-performance graphite materials is an important issue for the industrialization of fuel cell vehicles

Graphite bipolar plate is an important part of hydrogen fuel cell. In the working process of fuel cell, it plays an

 important role in gas distribution, electrical conductivity, heat conduction, drainage and so on. Finding graphite 

materials with excellent performance is an important issue for the industrialization of fuel cell vehicles.

04 Metal Continuous Casting

Casting process requires good materials

Continuous casting is a method of placing molten liquid metal in a mold of a specific shape to transform it into a solid

 metal of a specific shape. The mold is in contact with the metal liquid of more than a thousand degrees, which cannot

 corrode the metal, and the casting requires precise dimensions and smooth surface... Therefore, the material of the 

mold must have certain excellent characteristics.

The best choice of graphite materials for domestic copper continuous casting

Our technicians have developed special materials for copper continuous casting with in-depth research on materials. 

The metal mold made by the customer has high hardness, wear resistance and oxidation resistance, the service life is 

increased, and the product quality has achieved a leap.

We work with our customers to find graphite material solutions

05 Aerospace, Military

Stability priority Meets service requirements under complex working conditions

Graphite is widely used in aviation and aerospace fields due to its self-lubricating properties, 

easy forming and processing, thermal conductivity, thermal stability and stable chemical 

properties, such as sealing materials, throat lining materials, brush materials, etc., parts 

of aerospace equipment , Insulation materials and anti-radiation materials, such as 

graphite rings for aviation, piston rings, aviation bearings, graphite sealing components for aerospace.

In the military industry, isostatic graphite can be used for the manufacture of graphite 

nozzles for solid fuel rockets due to its small expansion coefficient, and the non-magnetic

properties of graphite can be used for the nose cone of ballistic missiles. It can be used as 

throat lining material for small rocket solid rocket motor. The electrical conductivity and 

wear resistance of graphite are used as brush materials for various engines, converters, and motors.

06 Nuclear Industry

Nuclear graphite - a stable and reliable material in the nuclear industry

China's independent third-generation nuclear power technology "Hualong No. 1" has not

 only laid the foundation for China to build a nuclear power technology powerhouse, but

 also promoted the development and upgrading of the technical quality of nuclear graphite 

materials in nuclear power. At present, China is vigorously developing the fourth-generation 

high-temperature gas-cooled reactor. With the upgrading of reactors, the demand for 

nuclear graphite has also risen. 

Ensure Purity

For graphite materials used in nuclear reactors, high purity and resistance to neutron 

radiation are key requirements. In order to ensure the purity, the company's nuclear 

grade graphite is much stricter than graphite electrodes in the selection of raw materials, 

process control, and finished product inspection. Through more than 10 processes, 

impurities are reduced, 

As a qualified supplier of CNNC, we provide solutions for nuclear grade graphite
