1050 H14 Stucco Embossed Aluminum Coil Sheet for Refrigeration/Electronics/Packaging (99.5% Pure, Enhanced Heat Dissipation)

Product Introduction

Premium 99.5% pure aluminum coil with engineered stucco embossing, optimized for thermal management and formability in critical applications. The H14 temper delivers optimal balance between strength and workability for refrigeration, electronics, and packaging industries.

Key Differentiators

? High Purity Aluminum (AA1050) - 99.5%+ Al content ensures superior conductivity
? Precision Embossing - Stucco pattern enhances surface area by 15-18%
? Thermal Efficiency - 225W/m·K thermal conductivity (ideal for heat dissipation)
? Regulatory Compliance - FDA/ROHS compliant versions available
