What are the materials of nuts
Carbon steel (including low-carbon, medium carbon, high carbon, and alloy steels such as 40Mn2, with high strength and low cost, commonly used for universal fastening).
Carbon steel (including low-carbon, medium carbon, high carbon, and alloy steels such as 40Mn2, with high strength and low cost, commonly used for universal fastening).
Stainless steel (such as 304/A2-70, 316/A4-80, 316L, corrosion-resistant, used in humid, chemical, or marine environments).
Copper and copper alloys (such as brass and bronze, with good electrical and thermal conductivity, used in electrical or explosion-proof applications).
Aluminum alloy (lightweight, corrosion-resistant, but with low strength, mostly used for aviation or non load bearing structures).
Titanium alloy (high strength to weight ratio, high temperature corrosion resistance, used in aerospace and high-end chemical industries).
Engineering plastics (such as nylon 6/6, insulated, non-magnetic, chemically resistant, used in electronic or anti-static scenarios).
