Key Takeaways
- iPhone 17’s anodized aluminum frame is more prone to scratches due to the brittle nature of the anodized layer, especially at sharp edges.
- Many visible marks are material transfer, not permanent scratches.
- Protective cases and careful handling significantly reduce damage risk.
- Lab tests show anodized aluminum scratches faster than titanium or stainless steel.
- Regional conditions (humidity, dust) can worsen surface damage; extra precautions are recommended.
Introduction
The iPhone 17 has been widely praised for its sleek design, sustainability, and performance.
A growing number of reports about visible scratches on the anodized aluminum frame - popularly termed “Scratchgate” - have drawn user attention and concern.
To provide clarity, we explored the material science behind these scratches, conducted scratch tests, and consulted materials experts.

Anodizing is an electrochemical process that thickens aluminum’s natural oxide layer.
Understanding Anodized Aluminum
Anodizing is an electrochemical process that thickens aluminum’s natural oxide layer.
This layer improves corrosion resistance, adds durability, and allows color finishes.
“Anodized aluminum provides a hard surface for everyday wear, but it’s brittle. Sharp edges, like the camera plateau on iPhone 17, are particularly prone to chipping or micro-scratches when impacted.”
Technical Insight: The anodized layer typically has a Mohs hardness of 3–4, compared with titanium’s 6. This explains why minor contact can leave visible marks.

Apple switched from titanium (iPhone 16 Pro) to anodized aluminum in the iPhone 17.
The Brittle Layer

Design Choices and Consequences
Apple switched from titanium (iPhone 16 Pro) to anodized aluminum in the iPhone 17.
Aluminum is lighter, easier to shape, and more sustainable, but introduces challenges in durability.
The iPhone 17’s camera plateau has sharp edges lacking curvature support, increasing scratch susceptibility.
Lab Observation: Using a Mohs scale 4 object to simulate everyday abrasion:
Material Scratch Result (24h) Notes
iPhone 17 Aluminum Moderate Edges scratched, flat surfaces mostly intact
Sharp Edges
The iPhone 17’s camera plateau has sharp edges lacking curvature support, increasing scratch susceptibility.
Lab Observation: Using a Mohs scale 4 object to simulate everyday abrasion:
- iPhone 17 Aluminum: Moderate scratches after 24 hours
- iPhone 16 Titanium: Minor scratches, mostly intact
- Samsung Stainless Steel: Minimal marking, flat surfaces slightly dulled

iPhone 16 Titanium Minimal Only minor edge marks
Samsung Stainless Steel Low Very few visible scratches
Material Transfer vs. Actual Scratches
Apple states many visible marks are material transfer, not scratches. This happens when dust, metal, or MagSafe accessories rub on the surface.
Material transfer is usually removable with a microfiber cloth (Economic Times, 2025
).
“Users often confuse material transfer with actual scratches. Proper care, including cases, prevents concentrated stress on edges and preserves the anodized layer.”
She notes anodized aluminum is ideal for aesthetic appeal but is not impact-proof, reinforcing the need for protective accessories.

Regional Context: India
In cities like Mumbai, Delhi, and Bangalore, environmental factors such as humidity, dust, and high temperatures exacerbate surface wear. Users should consider:
- Using TPU or silicone cases to protect edges
- Avoiding placement on abrasive surfaces
- Regular cleaning with a soft microfiber cloth
Pricing & Alternatives:
- iPhone 17 Pro (Aluminum): ₹1,59,900
- iPhone 16 Pro (Titanium): ₹1,79,900
This price difference highlights aluminum’s cost and sustainability benefits, but users must balance this with durability considerations.
Practical Advice for Users
- Case Protection: TPU or hybrid cases distribute impact and protect edges.
- Avoid Abrasive Surfaces: Keep keys, coins, and rough objects separate.
- Clean Material Transfer: Use microfiber cloths; avoid harsh chemicals.
- Monitor Vulnerable Areas: Camera plateau and edges are most susceptible.
- Warranty Awareness: Minor scratches from material transfer are typically not covered under Apple warranty, but severe damage may be.

Frequently Asked Questions
Q: Can scratches on anodized aluminum be removed?
A: Only minor material transfer marks can be cleaned; actual scratches are permanent.Q: Is anodized aluminum worse than titanium?
A: Aluminum scratches more easily, especially on sharp edges, but it is lighter and more sustainable.Q: Which cases are best for protection?
A: TPU, silicone, or hybrid cases that cover edges and corners fully.Q: Does scratching affect resale value?
A: Visible scratches can slightly reduce resale value. Proper care is recommended to maintain aesthetics.Q: How to differentiate material transfer from scratches?
A: Material transfer can often be wiped off; scratches are permanent abrasions on the anodized layer.Winding up
