Typical Aluminum Chemical Analysis

Key Features

High-Quality Aluminum Alloy: Made from 6061-T6 aluminum alloy for general durability applications and 7075-T6 aluminum alloy for high-stress applications, our aluminum flat washers offer an exceptional strength-to-weight ratio and natural corrosion resistance.

✔Wide Size Range: Standard metric sizes M3–M32 meet most fastening needs. Custom sizes are also available upon request to ensure a perfect match for your design.

✔Lightweight and Non-Magnetic: Aluminum washers are 60% lighter than steel washers, reducing overall assembly weight and avoiding magnetic interference, making them ideal for electronic devices and precision instruments.

✔Finish: Options include natural flat finish, anodizing (color or clear), powder coating, and custom plating (nickel, chrome) for enhanced appearance and corrosion protection.

✔Tight Tolerances: Each washer is manufactured using CNC stamping and precision machining to tight dimensional tolerances (±0.01 mm), ensuring uniform thickness and perfect roundness.
