Aluminum Perforated Sheets are widely used in architecture, decoration, and acoustic engineering. Here are the typical material classifications and their characteristics:
1. Basic Aluminum Alloys
1xxx Series (Pure Aluminum):
Models: 1050, 1060.
Features: High purity (≥99.5%), excellent corrosion resistance but low strength. Suitable for indoor decoration or low-load applications (e.g., acoustic ceilings, wall designs).
3xxx Series (Aluminum-Manganese Alloys):
Models: 3003, 3004.
Features: Enhanced strength (tensile strength: 150–200 MPa) with manganese additives, ideal for outdoor façades or sunshades requiring wind resistance.
5xxx Series (Aluminum-Magnesium Alloys):
Models: 5052, 5083.
Features: High strength (tensile strength: 250–350 MPa) and seawater corrosion resistance, suitable for marine or industrial environments.
2. Special-Treated Materials
Anodized Aluminum:
Process: Electrochemical oxidation (10–25 μm thickness).
Advantages: Improved hardness (up to HV300) and wear resistance; customizable colors for architectural exteriors.
Powder-Coated Aluminum:
Process: Electrostatic spraying with high-temperature curing (60–120 μm thickness).
Advantages: UV resistance and diverse color options (RAL standards), ideal for long-term outdoor use (e.g., airport terminals).
Note: Consider load requirements (e.g., wind pressure), acoustic performance (NRC 0.4–0.8), and cost (5xxx series costs ~30–50% more than 1xxx). Finite element analysis is recommended for optimizing hole patterns and thickness.
