Why Choose 3003 Aluminum Sheet Coil as the Ideal Insulation Protective Layer?
The so-called "insulation" or "thermal insulation" function of 3003 aluminum sheet coil usually does not refer to the material itself providing insulation, but rather that it is commonly used as a protective layer for insulation materials.
- 3003 aluminum sheet coil (also known as "insulation aluminum cladding" or "corrugated aluminum sheet") is wrapped around the outer layer of insulation materials (such as rock wool, glass wool) for pipelines and equipment, serving as protection, moisture barrier, corrosion resistance, and decorative finish.
- In applications requiring special thermal conduction or heat dissipation (such as battery cases and water-cooling plates in new energy vehicles), 3003 aluminum sheet may be combined with other aluminum alloys (such as 4343, 4045) to produce brazed sheets. This utilizes its thermal conductivity rather than insulation.
