Nut materials mainly include carbon steel, stainless steel, copper, and alloy steel. Different materials are suitable for different environments. For example, carbon steel is economical and durable, stainless steel is corrosion-resistant, and copper has good electrical and thermal conductivity.
Carbon Steel: The most common material, low cost and high strength, suitable for general industrial connection scenarios. It is usually galvanized or nickel-plated to enhance rust resistance.
Stainless Steel (e.g., 304, 316): Has excellent corrosion resistance and rust prevention properties, suitable for humid, outdoor, or high-hygiene environments, such as kitchens, bathrooms, and chemical equipment.
Copper and Copper Alloys (e.g., H59 Brass, Red Copper): Possesses good electrical and thermal conductivity and corrosion resistance, commonly used in electrical switches, faucets, valves, and injection-molded parts.
Alloy Steel: A high-strength material, suitable for heavy-load, high-temperature, or high-stress conditions, such as aerospace and heavy machinery.
