Saporito's Top 6 Finishes
1. Zinc Plating
Strong protection for steel parts — and it looks good, too
Zinc plating keeps your steel parts from rusting while giving them a clean, finished appearance. It’s a smart choice for fasteners, brackets, and automotive components. You can choose from different finishes like bright, yellow, or black for the look you want.
✅ Affordable
✅ Reliable corrosion protection
2. Anodizing
Sulfuric Anodize
Durable and dyeable — your aluminum never looked better
Sulfuric anodizing protects aluminum parts from corrosion and wear and gives
you tons of color options. It’s great for everything from consumer products to
aircraft parts, offering a clean look that lasts.
Can be dyed nearly any colorLooks sharp and holds up to wearLong-lasting protection
Chromic Anodize
Protection for sensitive aluminum parts
Chromic anodizing provides a thin, durable coating that protects aluminum without changing its dimensions. It’s ideal for parts that need inspection or operate in tight-tolerance environments. Especially important in aerospace where sulfuric acid entrapment can cause safety issues.
✅ Light finish, strong protection
✅ Great for aerospace or precision parts
✅ Highlights surface flaws for inspection
3. Zinc Nickel Plating
When corrosion resistance really matters
Zinc Nickel is built for harsh environments. It outperforms standard zinc plating, making it the go-to finish for automotive, marine, agriculture, or aerospace parts that need to last.
✅ Superior corrosion protection
✅ Great for tough jobs and demanding specs
✅ Excellent alternative to cadmium
📢 Fun fact: Saporito has the largest Zinc Nickel plating line in the world.
4. Hardcoat Anodizing
Built to take a beating — and keep performing
Hardcoat anodizing turns aluminum into a wear-resistant, electrically insulating surface that’s great for moving parts and high-impact applications. It can even be dyed for a sleek look.
✅ Extremely tough and durable
✅ Withstands friction and wear
✅ Great for electronics, machinery, and food service equipment
5. Electroless Nickel Plating
Smooth, even finish — even on the trickiest parts
Electroless Nickel gives consistent coverage on complex shapes, inside and out. It protects against wear and corrosion while offering a clean, stainless-steel look. It is a great replacement for stainless steel and hard chrome.
✅ No edge buildup
✅ Ideal for precise or oddly shaped parts
✅ Long-lasting protection
6. Chem Film Conversion / TCP
Lightweight coating with powerful protection
Chem film (also known as chromate conversion or TCP) protects aluminum and helps paint or adhesive stick better. It’s a go-to finish when weight and conductivity matter and you need a coating where dimensions do not change.
✅ Great for bonding or painting
✅ Low electrical resistance
✅ RoHS-compliant options available
