Silicon Carbide (SiC) is an extremely hard and durable ceramic material with many industrial uses. It offers resistance against corrosion, acids, and high temperatures – which makes it suitable for many different industrial settings. SiC is used in kiln shelves and furnace linings as a refractory material, while also serving as an abrasive known as carborundum. While SiC can be machined either green or biscuit state, in order to meet tight tolerances it must first be fully sintered first. Abrasive Silicon carbide (SiC) is an industry standard abrasive material used in grinding wheels and cutting tools, as well as in sandpaper for metal, stone and wood surfaces. Being hard and …

Aluminum oxide and silicon carbide are both ceramic substances utilized as abrasives, with silicon carbide having harder, sharper grains but being less durable than its aluminum oxide counterpart. While both can be used on nonmetallic surfaces like wood or plastics, silicon carbide cannot withstand higher tensile strength metals such as steel. Brown aluminum oxide is an exceptionally hard and long-wearing abrasive, capable of withstanding several blast cycles on softer materials such as rust and wood. White and pink varieties wear down more quickly but produce smoother finishes. Hardness Aluminum oxide (also referred to as brown fused alumina or AL2O3) is one of the most frequently used synthetic abrasives, often called …

A grinding wheel comprises two major elements – the abrasive grains which cut work material, and its bond which holds them securely together. When dulled abrasive grains become dulled or worn down, their bond breaks apart, exposing new cutting points while maintaining a consistent cut rate. Weiler offers wheels designed to minimize iron, sulfur and chlorine contaminants for improved workpiece grinding results in stainless steel and aluminum workpieces. Hardness Hardness of Abrasives in Grinding Wheels Determines their Cutting Capabilities Typically, harder grains provide more aggressive cuts. Bond Hardness Also Impacts Performance Hard bonds keep abrasive grains together better against grinding forces than soft bonds which permit easier breaking. Hard abrasives …
