• Plastic: Plastic shaft collars, such as those made from nylon or acetal, have limited temperature resistance compared to steel or aluminum. They can typically handle moderate temperatures but may deform or degrade at higher temperatures. Plastic collars are not as resistant to corrosion as metal collars but can still offer good resistance to certain chemicals and environmental conditions. Plastic collars are often used in applications where weight, cost, or electrical insulation properties are important factors.
• Brass: Brass shaft collars offer good temperature resistance and moderate corrosion resistance. They can handle a range of temperatures and are often used in applications where a combination of durability, conductivity, and aesthetics is required. Brass collars may tarnish over time but can still maintain their functionality and structural integrity.

It is important to note that the temperature and corrosion resistance properties of shaft collars can also be influenced by factors such as the specific alloy composition, surface treatments, and environmental conditions they are exposed to. When selecting shaft collars for your application, it is crucial to consider the temperature range and potential exposure to corrosive substances or environments. Consulting with manufacturers, reviewing technical specifications, and considering industry standards or guidelines can help ensure that you choose shaft collars with appropriate temperature and corrosion resistance properties for your specific needs.
