Al-Si 코팅 강철

설명

Al-Si Coated Steel is a carbon steel product protected by a hot-dip aluminum-silicon coating. The coating typically contains approximately 90% 알루미늄과 10% 규소, providing excellent heat resistance, 산화 저항, 부식 방지. Because of these advantages, it is widely used in automotive, 산업의, 건설, and energy-related applications.

Typical Coating Composition

The aluminum layer forms a protective oxide film, while silicon improves coating adhesion and controls the growth of the intermetallic layer between the coating and steel substrate.

주요 성능 특성

우수한 내열성

One of the most important advantages of Al-Si coated steel is its ability to maintain performance at elevated temperatures. The aluminum-rich coating resists scaling and oxidation much better than conventional carbon steel.

Outstanding Oxidation Resistance

When exposed to heat and air, the surface develops a dense aluminum oxide layer that slows oxidation and extends service life in demanding environments.

우수한 부식 방지

The coating acts as a barrier against moisture and corrosive atmospheres. Compared with uncoated steel, service life can be significantly increased in outdoor and industrial environments.

High Thermal Reflectivity

The bright metallic surface reflects radiant heat efficiently, making the material suitable for thermal management applications.

좋은 성형성

The material can be stamped, 굽은, rolled, and fabricated while maintaining coating integrity. This allows manufacturers to produce complex parts without sacrificing protection.
