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 aluminum alloy itself affects pricing. 1000-series pure aluminum (cost-effective but less durable) keeps overall costs low for both coatings, while 3000-series (manganese-infused) adds 10–15% to the price, and 5000-series (magnesium-enhanced) boosts costs by 20–30% for superior durability.

Aluminum purity also matters: higher-purity aluminum (≥99.7%) improves formability but increases costs by 5–8% for both coatings. When paired with PVDF’s premium resin, high-alloy, high-purity coils become the most expensive option—ideal for harsh environments. PE-coated coils, even with premium alloys, remain more affordable, making them suitable for budget projects needing moderate performance.

These choices let buyers balance cost and functionality: PVDF + high-alloy for long-term use, PE + standard alloy for short-term needs. Click here to know more.
