Types of Metals That Cause Scratching

Types of Metals That Cause Scratching

When it comes to maintaining the condition of your watches and jewelry, understanding which metals cause scratching is important. Many of us unknowingly place our high-end accessories in harm’s way by exposing them to everyday items that contain materials prone to causing damage. One common culprit is the MacBook. With its sleek aluminum body, it can scratch delicate surfaces on watches and jewelry.

In this post, we’ll explore the type of metal used in MacBooks, and how those interact with the metal commonly found in watches and jewelry.

1. Types of Metals in MacBooks

MacBooks are known for their sleek design and lightweight durability, thanks to the carefully selected materials used in their construction. Here’s a closer look at the metals used in these devices:

Aluminum Alloy:

The majority of MacBook bodies are made from high-quality aluminum alloy. This metal is chosen for its durability, lightweight nature, and resistance to corrosion. However, aluminum is a relatively soft metal compared to others used in technology and jewelry, making it susceptible to scratching harder metals.

 

Magnesium and Titanium Alloys (in some models):

In select MacBook models, magnesium or titanium alloys may be used to reinforce specific areas, further increasing the strength-to-weight ratio. These metals are considerably harder than aluminum and may cause scratches when in direct contact with softer metals.

2. Metals Commonly Used in Watches and Jewelry

Watches and jewelry are crafted using a variety of metals, each selected for its unique properties and aesthetic appeal. Let’s explore the most common metals and their hardness:

Stainless Steel:

Widely used in watch cases, bands, and clasps, stainless steel is a durable metal known for its resistance to wear and tear. However, when it comes into contact with softer metals, such as aluminum or gold, it can cause surface scratches.

Gold (18K, 14K):

Gold is often used in watches and jewelry in various karats. The higher the karat (e.g., 18K), the softer the gold. Pure gold (24K) is rarely used due to its extreme softness, so gold alloys are more common. Gold is prone to scratches from harder metals, including stainless steel and even aluminum in some cases.

Platinum:

Platinum is a dense and relatively hard metal used in high-end watches and jewelry. It is less likely to be scratched by softer metals but can leave scratches on softer materials like gold or aluminum.

Titanium:

Lightweight and durable, titanium is frequently used in modern watches. While it is scratch-resistant, it can scratch softer metals such as gold or aluminum when they come into direct contact.

Ceramics and Other Composites:

Some luxury watches use ceramic materials, which are incredibly scratch-resistant. They are unlikely to be scratched by common metals, but they can scratch softer metals like gold or aluminum.

 

3. Which Metals Scratch Each Other?

Aluminum vs. Stainless Steel:

Stainless steel, being harder, can scratch aluminum easily. This means if your watch has a stainless steel clasp or band and rests on an aluminum MacBook, it could leave marks on the laptop and vice-versa.

Gold vs. Aluminum:

Gold is softer than aluminum, making it vulnerable to scratches if it comes in contact with a MacBook’s aluminum surface. Even minor friction could cause visible scratches on gold jewelry or watch surfaces.

Platinum vs. Gold:

Platinum is harder than gold and can leave marks on gold jewelry. However, it is less likely to be scratched by softer metals.

Titanium vs. Aluminum:

Titanium is much harder than aluminum, making it a potential scratcher. Watch parts made from titanium should be kept away from aluminum surfaces.

5. Protecting Your Watches and Jewelry from Scratches

Given the varying hardness of metals, it’s crucial to protect your luxury items from accidental scratches caused by everyday devices like laptops. Consider the following tips:

Use a Protective Pad: Place a soft protective pad, like a WatchPad, on your laptop to prevent direct metal-on-metal contact.

 

Understanding which metals scratch on which can save your precious accessories from unwanted damage. The interplay between metals like aluminum, stainless steel, gold, and platinum means that even everyday items like laptops can pose a risk to your cherished watches and jewelry. Protecting these items with products like WatchPads ensures that your valuables remain in pristine condition, free from scratches and blemishes.
