Some materials can handle acids like a champ, while others… not so much…
Aluminium + Acid = Trouble! ⚠️
🛑 Reaction: Strong acids like hydrochloric or sulfuric acid eat through aluminium quickly, causing bubbling and corrosion.
🔥 Fun Fact: Aluminium forms a protective oxide layer, but acids strip it away, leaving it vulnerable!
🚫 Not recommended for acidic environments!
Stainless Steel – Tough but Not Invincible!
🔩 Reaction: Resistant to many acids, but…
💀 Weakness: Hydrochloric acid (HCl) and sulfuric acid can pit and corrode it over time!
💡 Pro Tip: Choose higher-grade stainless steel (316) for better acid resistance!
Brass – Say Goodbye to Strength!
⚙️ Reaction: Strong acids cause dezincification (zinc gets leached out, leaving weak, spongy copper behind!).
😱 Result: Metal weakens, turning dull and brittle.
🚧 Not a great choice for acidic conditions!
Polypropylene – Surprisingly Resistant!
🛡️ Reaction: Doesn’t react with most acids. Resistant to corrosion!
⏳ Lifespan: Holds up well, but extreme temperatures can reduce durability.
✅ A solid choice for acid handling!
Viton – The Acid-Proof Rubber?
🔄 Reaction: Handles many strong acids well! Resistant to chemicals and heat.
⚠️ Weakness: Some highly concentrated acids (like fuming sulfuric acid) can degrade it over time.
💪 Great for seals & gaskets in aggressive environments!
FEP – The Ultimate Acid Warrior!
🦸♂️ Reaction: Virtually inert to almost all acids.
🔥 Bonus: Can handle extreme temperatures!
💎 Best Choice for: Ultra-corrosive environments.
