Carbon Steel Nuts: Made from low-carbon (A3, Q235) or medium-carbon steel (No. 35, 45). High-grade versions use alloy steel (40Cr). They are cost-effective with a wide strength range. Surface treatments like galvanizing or blackening are used for rust resistance. Ideal for general machinery and steel structures.

Stainless Steel Nuts: Primarily austenitic (304, 316) or martensitic (410). 304 is for general atmospheric resistance, while 316 is suited for marine and chemical environments. Widely used in food, medical, and outdoor applications.

Brass & Aluminum Nuts: Brass offers excellent conductivity and non-magnetic properties, ideal for electrical and valve applications. Aluminum alloys (6061, 7075) are extremely lightweight, used in aerospace and racing fields.
