Aluminized Silicon Steel Coils in the New Energy Vehicle Industry

Introduction

As environmental awareness increases, the new energy vehicle industry has become a key focus of national development. With ongoing advancements, the selection of raw materials for vehicle components has gained significant attention.

TEDA Steel introduces aluminized silicon steel coils, a preferred material for new energy vehicle accessories due to its lightweight, high-temperature resistance, and corrosion resistance.

Why Choose Aluminized Silicon Steel?

1. Superior Formability and Lightweight Properties

• Automotive parts, such as stampings, press components, and accessories, require high plasticity and ductility.
• Aluminized silicon steel, composed of 90% aluminum and 10% silicon, is lightweight and has low density, making it ideal for vehicle applications.
• The material is available in various forms, including rods, sheets, foils, powders, strips, and wires, ensuring easy processing and shaping.

2. High-Temperature Resistance

• Automobile exhaust pipes and fuel tanks demand excellent heat resistance.
• The unique iron-alloy coating structure of aluminized silicon steel enhances its high-temperature stability.
• Heat resistance performance:
  • Maintains high reflectivity at 450°C.
  • Develops a gray coating at 480°C.
  • Withstands up to 650°C without oxidation or damage.

These properties make it a widely used material in the automotive industry.

3. Outstanding Corrosion Resistance

• Automotive components require high corrosion resistance due to frequent exposure to moisture and chemicals.
• During the hot-dip plating process, aluminum reacts with oxygen, forming a protective Al₂O₃ layer that passivates the surface, preventing corrosion.
• Even if the surface is scratched, the layer has a self-healing function, ensuring long-term durability.
• This makes solid aluminized silicon steel a preferred choice for rust-resistant automotive components.

Environmental Benefits and Future Outlook

• With societal progress and stricter environmental regulations, the demand for eco-friendly materials has grown.
• New energy vehicles require materials that meet high environmental and safety standards.
• The production of aluminum-silicon steel follows green manufacturing principles and complies with national environmental certifications.

As the automotive industry evolves, solid aluminized silicon steel will continue to play a crucial role in sustainable vehicle manufacturing.
