Steel-aluminum composite 75-75

The steel-aluminum composite radiator is a heating device developed by combining the unique properties of steel and aluminum. Through a specialized manufacturing process, steel and aluminum are integrated into a single unit, leveraging the strengths of both materials. Below, we provide a detailed introduction from multiple perspectives:

Material and Structure

1. Material Composition

Main structure:

Water pipelines typically use low-carbon steel (such as Q235), which offers high strength and excellent pressure resistance, making it ideal for water transmission in centralized or residential heating systems.

Cooling section: The outer layer is wrapped with aluminum alloy (such as 6063 aluminum alloy), leveraging aluminum's high thermal conductivity to enhance heat dissipation efficiency.

Composite Process:

The aluminum profiles are tightly bonded to the steel tubes using tube expansion processes—either mechanical or hydraulic expansion—ensuring a seamless connection between the two materials, minimizing thermal resistance, and enhancing heat dissipation performance.

2. Structural Form

Commonly found in column or tube-array designs, the散热片 features an airfoil shape wrapped around the outer side of steel tubes. Some products also include additional structures such as towel bars, making them ideal for spaces like bathrooms.
