Since the properties of brown aluminum oxide and green silicon carbide are very similar, many people cannot distinguish between the two items. Here are some introductions:
1. Different ingredients: The main content of green silicon carbide is SIC, and the main content of brown aluminum oxide is α-Al2O3;
2. Color: The color of green silicon carbide is dark green, and the color of brown aluminum oxide is brown-red;
3. Hardness: The hardness of green silicon carbide is 9.2, and the hardness of brown aluminum oxide is 8.9;
4. Raw materials: The raw materials of green silicon carbide are quartz sand, petroleum coke (or coal coke), and salt. The raw materials of brown aluminum oxide are bauxite and iron filings;
5. Usage: Brown aluminum oxide is suitable for the processing and grinding of various ordinary steels, high carbon steels, and alloy steels due to its high tensile strength. It can also be used as a substitute when some other abrasives are insufficient. Green silicon carbide is more suitable for fine grinding of materials, such as threads or grinding tools, etc. Grinding tools made of green silicon carbide can also process cemented carbide, glass, agate, etc.
After comparing different aspects, you should know the difference between brown aluminum oxide and green silicon carbide, so you can no longer confuse them.
