Foundries

Introduction

Graphite has several properties that make it valuable in the foundry industry:
1. High Carbon Content: Graphite has a high carbon content, which can improve the properties of the finished metal.
2. Thermal Conductivity: Graphite has excellent thermal conductivity, which is beneficial in many casting processes.
3. Electrical Conductivity: Graphite's high electrical conductivity is another important property.
4. Chemical Resistance: Graphite is resistant to chemicals, corrosion, and temperature, which makes it ideal for use in harsh environments.
5. Oxidation Resistance: Graphite is more oxidation resistant than other materials, which is particularly important in foundry applications.
6. Low Thermal Expansion Coefficient: Graphite has a low thermal expansion coefficient, which means it doesn't expand or contract much with temperature changes. This is crucial in foundry applications where materials are subjected to high temperatures.
7. Lubricity: Graphite has excellent lubricity or slipperiness, which can be beneficial in certain applications.
In addition to these properties, graphite is used in combination with other raw materials to improve component properties in moulding sands and dressings. It also acts as a separating agent. Please note that the specific properties can vary depending on the type of graphite used. It's always a good idea to check with Hifounder for the most accurate and up-to-date information.
