Why the Type of Metal in Your Car Matters More Than You Think

Not all metal is created equal—especially when it comes to your vehicle. Modern cars use a mix of different metals, and each one has a unique role in keeping you safe, efficient, and protected in a crash. At Solon Collision in Aurora, OH, we understand that repairing your vehicle the right way means using the correct procedures for the specific types of metal involved.

Here’s a breakdown of the most common types of metals found in today’s vehicles—and why it matters for your repair.

1. Mild Steel (Conventional Steel)

Where it's used: Older vehicles, structural frames, brackets, and inner supports

Key traits: Easy to repair and weld, but heavier and less resistant to corrosion

Mild steel is durable and cost-effective, but it’s being used less in newer vehicles due to weight and efficiency concerns. It’s still found in non-critical areas of many cars.

2. High-Strength Steel (HSS) & Ultra-High-Strength Steel (UHSS)

Where it's used: Door reinforcements, rocker panels, pillars, roof rails

Key traits: Extremely strong and resistant to deformation, but must be repaired carefully

High-strength steels are designed to absorb impact and protect the passenger cabin in a crash. However, these metals can’t be repaired like traditional steel. Improper heating or reshaping can compromise vehicle safety.

3. Aluminum

Where it's used: Hoods, doors, fenders, liftgates, and entire vehicle bodies (like Ford F-150)

Key traits: Lightweight, corrosion-resistant, and fuel-efficient—but not interchangeable with steel

Aluminum requires special tools, techniques, and a separate workspace to avoid cross-contamination with steel. At Solon Collision, we follow strict OEM procedures when working on aluminum panels to prevent galvanic corrosion and ensure safe repairs.

4. Magnesium

Where it's used: Structural support components, dashboards, steering columns.

Key traits: Lightweight but very reactive—cannot be welded or repaired like other metals

Magnesium is extremely flammable when overheated and is often replaced, not repaired. Our technicians are trained to identify these metals to avoid dangerous mistakes.

5. Carbon Fiber & Composites

Where it's used: Performance and luxury vehicles, bumpers, roofs, body panels.

Key traits: Very strong and light, but repairs are highly specialized

Carbon fiber cannot be welded or pulled. It typically requires replacement or advanced composite repair procedures. These materials are often used in electric vehicles and high-end models.

Why This Matters for Collision Repairs

Different metals behave differently under stress, heat, and repair techniques. That’s why manufacturers provide OEM repair procedures specific to each vehicle and each metal type. Using incorrect tools or skipping proper steps could:

• Weaken your vehicle’s crash protection

• Void OEM warranties

• Lead to premature corrosion or part failure

At Solon Collision, we’re committed to OEM-compliant repairs using the correct procedures, tools, and parts—because your safety depends on it.

Final Thoughts

You might not think about the metals in your car—but we do. Whether your vehicle is built with high-strength steel, aluminum, or advanced composites, Solon Collision has the training, equipment, and experience to handle it properly.

Don’t settle for guesswork. Trust the team that understands what your car is made of—and how to repair it right.
