3M™ Silicon Nitride Measuring Wheels help determine oil well depth. Made from high-strength, lightweight 3M™ Silicon Nitride, these measuring wheels offer excellent wear resistance and accuracy in extreme temperature conditions. As an alternative to wheels made with conventional metal alloys, 3M™ Silicon Nitride Measuring Wheels deliver excellent wear resistance and a low coefficient of thermal expansion, which improve accuracy, even in extreme temperatures.
3M™ Silicon Nitride is an extremely hard and corrosion-resistant ceramic material that is 60% lighter than steel. This material, Sintered Silicon nitride (Si₃N₄), is designed to offer a combination of excellent properties, including thermal and impact shock resistance, electrical insulation, and wear resistance. 3M™ Silicon Nitride offers a wide degree of design flexibility, making it an outstanding alternative to stainless steel, superalloys, tungsten carbides, and first-generation ceramics such as Al₂0₃ and ZrO₂. These performance benefits make 3M™ Silicon Nitride a perfect solution for measuring wheels.
