For metalworkers, grinding wheels are essential tools for smoothing, sharpening, and shaping metal surfaces. These wheels consist of different abrasive materials bonded to fiberglass layers. Each abrasive material offers different characteristics that makes it ideal for certain types of grinding operations. Learning your way around the different types of abrasives used in grinding wheels is essential for improving the efficiency and quality of your work. Read on to explore some of the most common abrasive types and their respective applications.
Aluminum Oxide
Aluminum oxide is the most common grinding wheel abrasive. It’s a versatile, cost-effective material that works with a wide variety of metals, including carbon, bronze, wrought iron, and alloy steel. Aluminum oxide is a tough and durable material with a sharp, fast cut. It’s a great standard option that delivers consistent quality and dependable performance for a variety of needs. That said, there are other abrasive options that offer a better cut rate and durability for more specialized needs.
Silicon Carbide
Silicon carbide is a synthetic material that is harder and more brittle than aluminum oxide. It is excellent for grinding non-ferrous metals, such as aluminum, copper, and bronze. Silicon carbide is also ideal for grinding non-metal materials like stone or glass. The biggest advantage of silicon carbide abrasives is how sharp they are. This makes them ideal for projects that require a fast cut rate. However, because silicon carbide is so brittle, it doesn’t have the durability of other abrasives and requires replacing more often.
Zirconia Alumina
If you need a tough, long-lasting abrasive, zirconia alumina is the way to go. Zirconia alumina consists of a blend of aluminum oxide and zirconium oxide. It is harder, tougher, and more durable than most other abrasives. It has outstanding wear resistance and works well in high temperatures and pressures. This abrasive’s extreme strength makes it ideal for working with steel or steel alloys.
