Square Washer Materials

Metal Materials: This is the most common material for square washers, especially in construction and machinery.

Steel: Includes common carbon steel and galvanized steel (such as galvanized square washers, hot-dip galvanized square washers). They are low-cost and high-strength, widely used in general industrial fastening.

Stainless Steel: Represented by 304 stainless steel, it has excellent corrosion resistance and is suitable for humid, outdoor, or high-hygiene environments, such as curtain walls and food machinery.

Copper Alloys: Such as red copper (T2) and brass (H62), mainly used for electrical connections and precision instrument parts that require good electrical conductivity, thermal conductivity, or corrosion resistance.

Non-Metal Materials: These materials are mostly used for special functions such as shock absorption, insulation, or anti-slip.

Plastic/Rubber: Examples include EVA, silicone, PVC, etc., commonly made into anti-slip mats or insulating washers, used at the bottom of furniture and electrical equipment.

Composite Materials: Some square washers for special purposes may use engineering plastics or fiber-reinforced materials to meet the requirements of lightweight and high strength.
