Extended Long Aluminum-Steel Blind Rivets: Definition, Advantages & Specifications

Extended ordinary aluminum-steel blind rivets are high-performance blind fasteners engineered for thick workpieces and multi-layer assembly. They feature an extended shank (lengths from 10mm to 60mm, customizable) with an aluminum alloy body and high-strength steel mandrel, delivering reliable one-side installation for total workpiece thicknesses of 5mm–45mm.

Following standard blind rivet mechanics, the steel mandrel is pulled to expand the aluminum body, creating a tight, permanent clamp. Unlike short standard rivets, extended versions penetrate deep stacks and maintain consistent clamping force in heavy-duty applications.

Core Advantages Over Standard Rivets & Other Extended Fasteners

1. Extended Length for Thick Assemblies

The lengthened shank solves the common failure of standard rivets in thick materials. It smoothly penetrates stacks up to 45mm (e.g., 30mm steel plate + aluminum profile) and forms a full clamping footprint, while same-diameter standard rivets lack reach and fail to secure.

2. Aluminum-Steel Composite Performance Balance

• Aluminum body: Lightweight, corrosion-resistant, compatible with aluminum, copper, and non-ferrous metals.
• Steel mandrel: Tensile strength up to 280MPa for stable setting without deformation.

Compared to all-steel rivets: 35% lighter and eliminates galvanic corrosion.Compared to all-aluminum rivets: 40% higher shear strength for improved joint integrity.

3. Cost-Effective & Easy Installation

As a general-purpose extended fastener, it uses a simple, reliable structure (no multi-lock/bulb designs) to lower production costs. Priced only 15%–20% above standard rivets—far less than specialty extended fasteners. Works with standard manual/pneumatic rivet tools; no special equipment required.
