How does the aluminum in MacBook Pros react with human hands?

The aluminum in MacBook Pros generally does not react chemically with human hands in a harmful way. However, some users have reported skin irritation or allergic reactions, which are often attributed to other components rather than the aluminum itself. These reactions are more commonly linked to nickel compounds that may be present in the coatings or finishes used on Apple's aluminum products13.

Key Points:

• Aluminum Durability: Aluminum in MacBook Pros is durable and resistant to wear from human hands, including oil and sweat. It can be cleaned with a damp cloth or alcohol without damage2.
• Nickel Allergy: Some users experience skin irritation due to nickel allergies. This is because nickel compounds are sometimes used in the coatings of aluminum products1.
• Prevention Measures: To avoid skin irritation, users can cover the metal parts with protective films or use alternative products with non-metallic surfaces13.

Overall, while aluminum itself is not typically reactive with human skin, other materials used in the manufacturing process can cause issues for some individuals.
