One of the most widely used plastics in the world, especially as a bearing and wear material. Frequently used as replacements for bronze, brass, aluminum, steel and other metals, as well as other plastics, wood, and rubber. Cast Nylons offer extremely good wear resistance, coupled with high tensile strength and modulus of elasticity. They also have high impact resistance, a high heat distortion temperature, and resist wear, abrasion, and vibration. In addition, nylons can withstand sustained contact with a wide variety of chemicals, alkalies, dilute acids or oxidizing agents.
Another important factor, both economically and mechanically, is the relative light weight of nylon, approximately 1/8 the weight of bronze, 1/7 the weight of cast iron, and 1/2 the weight of aluminum which reduces both the inertial and static loads and eases the handling of large components during maintenance or replacement procedures.
