When selecting door hardware, the material and finish you choose impact not only the aesthetics but also the durability and longevity of your hardware. With so many options available, it’s essential to understand the benefits and drawbacks of different materials. Here’s a breakdown of popular door hardware materials and finishes, highlighting what makes Ageless Iron’s cast iron a lasting and worthwhile choice.
Hollow Metal and Budget Hardware: The Downside of Cheap Materials
Many mass-produced, budget-friendly door knobs—often the ones that come standard in new homes or are sold in big-box stores—are made from lightweight materials such as thin stamped steel or hollow zinc alloy.
While these budget options may seem appealing initially, they often don’t stand the test of time. The difference is noticeable—lightweight knobs feel hollow and lack the sturdiness that high-quality materials like solid brass, stainless steel, or cast iron have to offer. Over time, these cheaper materials can wear out, leading to a frustrating cycle of replacing hardware that doesn’t hold up.

Zinc Alloy: Affordable but Less Durable
-
Pros:
- Cost-effective and widely available.
- Can be molded into various shapes and designs.
-
Cons:
- While durable, zinc is not as strong as brass or cast iron, especially for heavy-duty doors or high-traffic areas.
- While zinc is rustproof, it can corrode over time, especially in harsh environments.
- Lacks the heft and strength of solid metals.
- No true polished brass or unlacquered finishes.
Aluminum Alloy: Lightweight and Corrosion-Resistant
-
Pros:
- Naturally resistant to corrosion.
- Lightweight and easy to install.
- Can be finished in various colors and styles.
-
Cons:
- Less durable than brass, steel, or cast iron.
- Can feel less substantial due to its lightweight nature.
- A handle that is too light can affect its ease of operation.
- Prone to dents and scratches over time.
Built to Last: The Best Metals for Door Hardware
When selecting door hardware, the material you choose impacts more than just aesthetics—it determines longevity, strength, and overall performance. High-quality metals offer durability and a timeless feel, while lower-quality options may wear out quickly. Below, we explore three of the most reliable materials for door hardware: stainless steel, solid brass, and cast iron.
Stainless Steel: Modern and Low Maintenance
-
Pros:
- Is a non-porous material, making it easy to clean and maintain, and less likely to harbor bacteria.
- Known for its strength and resistance to wear and tear, making it a long-lasting option for door hardware.
-
Cons:
- Can show fingerprints and smudges easily.
- Not as heavy or solid-feeling as brass or cast iron.
- The quality and rust resistance of stainless steel can vary depending on the grade.
- Risk of galvanic corrosion when combined with other metals in a door handle.
Solid Brass: Classic and Durable
-
Pros:
- Highly durable and resistant to corrosion.
- Unlacquered versions develop a rich patina over time, adding character.
- Heavy, giving a high-end feel and solid operation.
- Being a copper alloy, has natural antimicrobial properties that can help prevent the spread of bacteria and germs. This only applies when it is unlacquered.
- Relatively easy to clean and maintain, requiring only occasional wiping with a soft cloth.
-
Cons:
- More expensive than other materials.
- It requires regular polishing to maintain its luster when unlacquered. (When lacquered, it only requires wiping with a soft, wet cloth)
- Some finishes may tarnish or discolor over time when unlacquered. (When lacquered, this is not an issue.)
- Can be recycled indefinitely.

Cast Iron: Strength and Timeless Appeal

-
Pros:
- Known for its robustness and resistance to wear and tear, meaning it can withstand heavy use and harsh conditions without losing its integrity.
- Cast iron handles are designed to last for many years, making them a reliable and cost-effective option in the long run.
- Cast iron is relatively easy to clean and maintain, requiring only occasional wiping with a soft cloth and mild soap.
- Perfect for traditional, farmhouse, or industrial interiors.
- Cast iron is a fire-resistant material, which can help protect doors and the surrounding area in case of a fire.
-
Cons:
- Requires proper finishing to prevent rusting. (Ageless Iron’s door knobs are zinc plated prior to powder coating to prevent rust.)
- Heavier than other materials, requiring sturdy installation.
