Roland, the changes we have made are deliberate.

In the design of our aluminium door hinges, we've integrated a meticulously crafted pin arrangement. The hinges feature bushes that are accurately positioned, with the pin being securely pressed into the upper hinge. This use of a 'spline' effectively prevents any rotation of the pin in both halves of the hinge, ensuring a robust design that maintains structural integrity over time.

However, adopting this method can compromise the 'quick release' mechanism of the door. The necessary fit of the splined pin might cause issues with removal if one attempts to detach it from the aluminium section of the hinge.

Conversely, if a simple floating pin that operates in both hinge parts is utilized, it could lead to wear issues unless we install bushes on both sides. Our innovative design incorporates the bushes into the outer sections, allowing for the use of a floating pin that is machined with a flat surface. This is complemented by a small stainless steel 'grub' screw which locks the pin in place, ensuring that it does not rotate within the central part of the hinge.

To mitigate wear, we use a 316 stainless steel pin paired with a machined bronze bush, which requires minimal lubrication. The low coefficient of friction between stainless steel and bronze, approximately 0.1, contributes to a reliable performance with minimal wear, especially when used with lightweight doors. Moreover, we intentionally design the stainless steel pins to be slightly oversized, ensuring that when we ream the bushes post-installation, the clearance is minimal, which effectively eliminates any possibility of rocking.

It’s crucial to note that these components are specifically engineered for lightweight applications and are not intended for heavy-duty usage, such as those encountered in automotive road applications where wear rates would be significantly higher.

When it comes to hinges, the choice usually boils down to two popular materials: stainless steel and aluminum. Understanding the differences between these materials is crucial when considering which to install for shutters, doors, or windows in your home.

Your choice of hinge material significantly depends on the application. When mounting window shutters or doors, both stainless steel hinges and aluminium door hinges offer excellent performance, yet they behave differently based on their properties.

Let’s evaluate the advantages and disadvantages of each material:

Benefits of Stainless Steel

1. Strength-to-weight ratio: Stainless steel offers a superior strength-to-weight ratio compared to aluminum, allowing for thinner, yet stronger designs with a higher load-bearing capacity. This efficiency also translates into cost savings over time.

Additionally, advancements in steel fabrication have streamlined the processes of cutting, machining, and welding, making modern construction straightforward.

2. Low and high-temperature resistance: Perfect for outdoor applications, stainless steel can handle extreme temperature conditions without issue.

3. Resistant to corrosion: Stainless steel is ideal for wet or coastal environments, as it naturally resists rust. While some wear can occur over time, especially in extreme conditions, the overall resistance remains a substantial advantage.

For harsher conditions, consider the Coastal Series from iHinge, which features Marine Grade 316 stainless steel for optimal protection against corrosion.

4. Aesthetics: The visual appeal of hinges is important, especially since they are not always concealed. Manufacturers can customize the design and finish of stainless steel hinges, which are available in varied shapes, sizes, and coatings.

Disadvantages of Stainless Steel

Although stainless steel hinges may require a higher upfront cost, they typically outperform alternative materials over their lifespan, making them a more economical choice in the long run.

Aluminum Hinges

Aluminum hinges are recognized for their lightweight nature, making them a preferred option in aviation, trains, and other transportation mechanisms. They are typically about one-third the weight of their stainless steel counterparts.

However, to achieve the necessary strength, aluminum hinges often incorporate various alloy elements. When it comes to corrosion and rust, aluminum is more susceptible than stainless steel, though there are coatings available that can enhance its resistance.

Choosing anodized aluminum hinges can also be a budget-friendly option since they generally come at a lower price point than stainless steel. Plus, aluminum is eco-friendly due to its recyclability once it has reached the end of its useful life.

Which Hinge Material is Best?

When weighing the options between stainless steel and aluminum hinges, stainless steel tends to be the preferable choice. While the initial costs may be higher, their remarkable durability, strength, and resistance to corrosion ultimately lead to savings and aesthetic advantages over time. They complement any property beautifully!
