Spotlight on Almag 535: The Premium Alloy for Marine Hardware

When it comes to crafting high-quality marine hardware, material choice is critical. At Atkins & Hoyle, we rely on Almag 535 (also known as aluminum alloy 535) to deliver durable, corrosion-resistant products tailored for the demanding marine environment. Let’s dive into why Almag 535 is the perfect choice for boaters and their vessels.


What is Almag 535?

Almag 535 is a high-strength aluminum-magnesium alloy known for its exceptional performance in challenging environments. Its unique composition offers a balance of strength, corrosion resistance, and machinability that is ideal for applications across multiple industries, including marine aluminum sand casting.


Why Almag 535 is Ideal for Marine Hardware

Superior Corrosion Resistance

  • One of the most critical features for marine applications is the ability to withstand corrosive saltwater environments. The high magnesium content in Almag 535 (6.2–7.5%) ensures outstanding corrosion resistance, making it perfect for long-term exposure to water and marine conditions.

High Strength-to-Weight Ratio

  • Almag 535 offers the strength of a robust material without the added weight. This characteristic is essential for boaters who want lightweight yet durable hardware that doesn't compromise performance.

Dimensional Stability

  • Products made from Almag 535 maintain their shape and integrity over time, even under significant mechanical stress or varying temperatures. This dimensional stability ensures that critical components like davits, hatches, and mounts function reliably.

Ease of Machining

  • The alloy's exceptional machinability means that we can craft precisely engineered parts for custom applications. Whether it’s for dinghy davits, solar mounts, or radar arches, Almag 535 allows us to achieve exact specifications.

Challenges and Our Expertise

While Almag 535 offers incredible benefits, it is known to be challenging to cast due to its tendency to cool quickly and shrink during the process. This can lead to imperfections if not managed properly.

At Atkins & Hoyle, we’ve perfected our casting techniques through years of experience and innovation. By leveraging advanced casting methods and stringent quality controls, we produce flawless marine hardware that stands up to the test of time.
