One-third the weight of steel, these washers are commonly used in robotics, automation, and other applications that have weight limits. They're an alternative to stainless steel for rust resistance.
Corrosion-Resistant 1100 Aluminum—The best corrosion resistance of all the aluminum washers we offer. These are common in chemical and food processing industries since they stand up to salt water, mild acids, and detergents. However, they aren't as strong as 2024 aluminum.
