Aluminum Split Ring Lock Washers

When should I use aluminum lock washers?

Aluminum split ring washers are chosen where weight, non-magnetic properties, or metal matching matter, such as aerospace, drone, RC, and aluminum-framed assemblies. Pairing aluminum washers with aluminum hardware also limits galvanic corrosion between dissimilar metals. The split ring provides light-duty vibration resistance, biting the surface and holding spring tension as the fastener is torqued. Because aluminum is softer than steel, these suit light to moderate loads rather than high-strength joints. Tighten to the correct torque and avoid over-tightening, which can flatten the softer ring.

Why choose aluminum split ring lock washers

• Lightweight: about one-third the weight of steel.
• Non-magnetic: for electronics and sensitive assemblies.
• Corrosion resistant: naturally resists rust.
• Metal matching: pairs with aluminum hardware to limit galvanic corrosion.

Common applications for aluminum split ring lock washers

• Aerospace, drone, and RC builds
• Aluminum-framed assemblies
• Weight-critical and non-magnetic hardware
• Light-duty vibration resistance

Aluminum Split Ring Lock Washers FAQ

Are aluminum split ring washers strong enough for structural use?

No. Aluminum is softer than steel and suits light to moderate loads. For structural strength, choose steel, stainless, or Grade 8.

Why pair aluminum washers with aluminum hardware?

Matching metals limits galvanic corrosion that can occur between dissimilar metals in wet environments.

Are aluminum washers magnetic?

No. Aluminum is non-magnetic, which suits electronics and instrument work.
