We supply Aluminum 5083 Fasteners for applications that require a combination of low weight, corrosion resistance and dependable mechanical performance. Alloy 5083 is an aluminium-magnesium alloy with manganese and chromium additions. Unlike heat-treatable aluminium alloys, its strength is primarily developed through strain hardening rather than precipitation heat treatment.
Our range includes Marine Grade 5083 Aluminum Bolts, nuts, screws, studs, washers and threaded fasteners in suitable sizes, forms and tempers. The material is especially valued where fasteners may be exposed to saltwater, moisture and demanding outdoor conditions.
5083-H116 / 5083-H321 Aluminum Fasteners are commonly considered for marine and structural service, while 5083-H111 Soft Annealed Fasteners offer higher formability where this is more important than maximum strength.

What are Aluminium 5083 Fasteners?
Aluminium 5083 Fasteners are corrosion-resistant, lightweight fasteners manufactured from Alloy 5083, a high-strength non-heat-treatable aluminium-magnesium alloy. They are particularly suitable for marine, offshore, transportation, chemical and structural applications because of their good resistance to seawater, low density and useful mechanical strength. Common tempers include 5083-H116, 5083-H321 and 5083-H111. These fasteners are also identified as UNS A95083, EN AW-5083 and Werkstoff 3.3547 / DIN 3.3547.

5083-H116, H321 and H111: Which Temper Should You Choose?
➤ 5083-H116 Fasteners
5083-H116 Aluminum Fasteners are suitable when good strength and marine corrosion resistance are important. H116 is associated with strain-hardened aluminium products intended for marine applications.
➤ 5083-H321 Fasteners
5083-H321 Aluminum Fasteners provide a combination of strength, corrosion resistance and resistance to stress-corrosion-related degradation. They are commonly considered for demanding marine and structural environments.
➤ 5083-H111 Fasteners
5083-H111 Soft Annealed Fasteners have a softer condition with better formability. They can be useful for applications involving greater forming requirements, although their strength is lower than harder tempers.
For a marine project, the correct temper should be selected based on the actual fastener design, loading, exposure and governing specification rather than simply choosing the highest-strength condition.
