Graphite Ingot

Graphite Ingot Manufacturer

Graphite ingots have several key features, making them useful in various industries:

• High density: Graphite ingots have a bulk density ranging from 1.78 to 1.9 g/cm3. This provides excellent mechanical strength and resistance to compression.

•  Low ash content: The ash content of graphite ingots is typically ≤0.15%. This ensures high purity and reduced contamination in various processes.

• Corrosion resistance: Graphite ingot has excellent impact resistance and acid and alkali corrosion resistance. The stable performance of graphite ingot ensures the reliability of the product.

• Electrical: Graphite is a carbon element with a high degree of lattice integrity. Its’ lattice shape is similar to honeycomb, and has excellent electrical conductivity. Although it might be less effective compared to metals, the high directivity and compressibility allow it to have an advantage in some applications. For example, graphite can serve as a conductive film, replacing metals to achieve higher device performance and reduce the cost of materials. The preparation process of graphite conductive films is relatively easier and cheaper, which allow it to be mass-produced. In many cases , it last longer than metal films.

• Sustainable material: Graphite ingot molds are very durable and have a long service life, reducing the need for frequent replacement and minimizing waste. In addition, graphite is recycled, this provides a more sustainable manufacturing process. Then discarded molds can be reprocessed and used for new applications.

As above, graphite ingot has the characteristics of small thermal inertia and rapid heating capacity. It can resist to high temperature and good heat shock. As graphite ingots have large radiation area and high heating efficiency, it offers stable basic performance.

Applications of Graphite ingot

Metallurgy: Metallurgy use graphite ingots for precision casting metals such as aluminum and even high-value metals such as gold, silver, platinum, and palladium. Because of its’ excellent thermal conductivity and self-lubrication properties, graphite ingot can improve the casting speed. Graphite ingots can improve the yield and product quality in many ways. They ensure size is accurate, the surface is smooth, the crystallization structure is uniform.

Glass manufacturing: Glass manufacturing also use graphite ingots a lot. Such as the production of glass containers and other glass products. It can cool down molten glass without cracking under extreme heat.

Jewelry making: Precious metals like gold and silver jewelry needs more cautious when manufacturing. The properties of graphite make the customization process of ingots relatively easy. It can cool down molten precious metals without cracking under extreme heat.

Non-ferrous metal continuous casting: Many manufacturers have successfully put artificial graphite material in pressure casting non-ferrous metals. The production of zinc alloy and copper alloy castings have been used in automotive parts.

Technical Specifications of Graphite Ingots

High purity graphite is a kind of carbon material with high purity, and its’ technical specifications vary according to different grades. The following are several main graphite products and their corresponding indicators:

1. LC50-99.9: has a high fixed carbon content, reaching 99.90%, and a very low water content, only 0.20%. This high purity makes it suitable for strict sealing applications. Such as as a flexible graphite sealing material, ensuring that it maintains good performance under extreme conditions.

2. LC300-99.9: Its fixed carbon content is slightly lower, but it is still more than 99.9%. And the moisture content is controlled below 20.0%. These make the ingots suitable for occasions with high lubrication performance requirements. So it may be used as a lubricant base material.

3. LC180-99.9 and LC(I)150-99.99: These grades of graphite also have high purity, moisture content controlled within 20.0%. They are suitable for specific industrial uses. Such as possibly as a material requiring higher purity and stability.
