Which Is More Corrosion-Resistant: Copper or Aluminum Coils?
Corrosion resistance is a make-or-break factor for HVAC coils, and copper outperforms aluminum in challenging environments. Copper forms a dense natural oxide film that defends against salt spray, industrial waste gas, and hard water scaling. Near chemical plants, copper-coil AC corrosion is just 1/5 that of aluminum. Aluminum relies on a thin oxide layer for protection, which works in...

How Do Raw Material and Alloy Choices Impact PVDF vs. PE Coil Prices?
Raw materials and alloy types play a key role in the final cost of both PVDF and PE-coated aluminum coils—but how do these choices differ between the two? First, the coating resins drive base cost differences: PVDF’s fluoropolymer resins are significantly more expensive than PE’s polyester resins, accounting for a large portion of their price gap. Beyond coatings, the...
