Why Material Choice Makes or Breaks Your Enclosure
Ever wonder why some sheet metal enclosures outlast others? The secret starts with material selection. Aluminum alloys (3003/5052) dominate 68% of industrial applications due to their corrosion resistance, while stainless steel remains crucial for extreme environments [IndustryWeek 2024]. We learned this the hard way when our team’s 2025 telecom project initially used mild steel, only to discover rust spots within 3 months of coastal deployment.
Material Comparison Table
| Aluminum | Stainless Steel | |
|---|---|---|
| Cost | $2.8/kg | $5.1/kg |
| Corrosion Resistance | Excellent | Superior |
5-Step Fabrication Blueprint
- Laser-cut panels with ±0.1mm precision
- Form bends using CNC press brakes
- Apply powder coating at 200°C
⚠️ Common Pitfall Alert
Never skip prototype testing! A major automotive supplier recently recalled 12,000 units due to improper vent hole placement.
FAQs
- How thick should enclosure walls be?
- Typically 1.2-2.5mm for industrial use
