Understanding Cast Aluminum and Its Properties
Cast aluminum is created by pouring molten aluminum into molds to form intricate shapes, offering a lightweight yet strong material ideal for furniture, architectural components, and more. Often alloyed with elements like silicon, magnesium, or copper, cast aluminum gains enhanced strength, castability, and corrosion resistance tailored to specific applications.
At ASUZAC ACM, our cast aluminum furniture, such as tables, chairs, and benches, benefits from these alloys, ensuring durability and aesthetic versatility. Our table and chair product line features powder-coated finishes that further protect against environmental factors, making them perfect for outdoor use.
Why Doesn’t Cast Aluminum Rust?
Rust is a form of iron oxide that occurs when iron reacts with oxygen and moisture. Since aluminum is a non-ferrous metal, it lacks iron and therefore does not rust. Instead, when exposed to air, cast aluminum forms a thin, protective layer of aluminum oxide. This natural barrier shields the metal from further oxidation, moisture, and pollutants, enhancing its durability.
However, while cast aluminum doesn’t rust, it can experience other forms of corrosion, such as pitting or galvanic corrosion, under specific conditions. ASUZAC ACM’s furniture is designed with protective coatings to minimize these risks, ensuring long-lasting performance.
Types of Corrosion in Cast Aluminum
Although cast aluminum doesn’t rust, it can corrode in certain environments. Understanding these corrosion types helps maintain the integrity of your furniture:
- Pitting Corrosion: Small, localized holes form due to chloride exposure, common in coastal areas with saltwater.
- Galvanic Corrosion: Occurs when aluminum contacts dissimilar metals, like steel or copper, in the presence of moisture.
- Crevice Corrosion: Develops in confined areas where moisture is trapped, such as joints or crevices.
ASUZAC ACM’s cast aluminum furniture, crafted with V-Process Technology, features smooth surfaces and powder coatings that reduce crevices and protect against these corrosion types, making our products ideal for diverse environments.
Factors Influencing Cast Aluminum Corrosion
Several factors can affect the corrosion resistance of cast aluminum:
- Environmental Conditions: High humidity, saltwater, or extreme temperatures can challenge the oxide layer, particularly in marine settings.
- Chemical Exposure: Acidic or alkaline substances, such as cleaning agents, can weaken the protective layer if not properly managed.
- Mechanical Stress: Physical damage, like scratches, can expose bare aluminum to corrosive agents.
- Electrochemical Reactions: Contact with more noble metals in wet conditions can trigger galvanic corrosion.
ASUZAC ACM’s powder-coated furniture mitigates these risks, offering enhanced protection for outdoor use in patios, gardens, or commercial spaces.

Is Aluminum Oxidation Harmful?
Unlike rust, which weakens iron-based metals, aluminum oxidation is generally beneficial. The aluminum oxide layer is tough, self-healing, and prevents further corrosion, enhancing durability with minimal maintenance. However, in harsh environments, such as coastal areas or acidic conditions, the oxide layer may weaken, leading to pitting or other corrosion types.
ASUZAC ACM enhances this natural protection by applying powder coatings to our furniture, ensuring it remains corrosion-resistant even in challenging conditions. For added durability, our products can be anodized, thickening the oxide layer for superior resistance and aesthetic appeal.
Protecting Cast Aluminum from Corrosion
To ensure cast aluminum remains corrosion-free, ASUZAC ACM recommends the following strategies:
- Powder Coatings: Our furniture features durable, UV-resistant powder coatings that create a barrier against moisture, salt, and chemicals.
- Anodizing: An electrochemical process that thickens the oxide layer, enhancing corrosion resistance and allowing for vibrant color options.
- Regular Maintenance: Clean surfaces with mild soap and water to remove dirt, salt, or debris that could compromise the protective layer.
Best Practices for Maintaining Cast Aluminum Furniture
To keep ASUZAC ACM’s cast aluminum furniture in pristine condition:
- Clean regularly with a soft cloth, mild soap, and water, rinsing thoroughly to remove residue.
- Avoid harsh chemicals, such as bleach or ammonia, unless specified for the coating.
- Use protective covers during off-seasons to shield from rain and UV exposure.
- Inspect for scratches or damage, addressing them promptly to prevent corrosion.
These practices ensure your furniture remains durable and attractive, even in outdoor settings.
Comparing Cast Aluminum to Other Metals
Here’s a table comparing cast aluminum to other common metals for corrosion resistance:
Material | Pros | Cons | Best For |
Cast Aluminum | Lightweight, rust-free, naturally corrosion-resistant, recyclable. | Susceptible to pitting/galvanic corrosion in harsh environments. | Outdoor furniture, coastal areas. |
Cast Iron | Strong, durable, ideal for heavy-duty applications. | Prone to rust, heavy, requires maintenance. | Structural supports, indoor use. |
Stainless Steel | Highly corrosion-resistant, strong, durable. | Expensive, heavier than aluminum, can pit in chloride environments. | High-durability, industrial settings. |
Mild Steel | Strong, affordable, ideal for structural projects. | Highly rust-prone, requires coatings, heavy. | Cost-effective construction. |
