In metalworking, manufacturing, and logistics, preventing corrosion is critical. Whether you're shipping precision components, storing parts long term, or preparing metal for downstream processing, metal protection fluids — also called corrosion preventatives — play a vital role.

This guide explores the metal protection fluid category, the benefits of using rust preventatives, and how FERROCOTE® 5856 BF from Quaker Houghton delivers long-lasting, barium-free protection trusted across industries.

Metal protection fluids are specially formulated to prevent corrosion by forming a barrier that blocks moisture, air, and other corrosive elements from reaching the metal surface. They're used in nearly every stage of the metal lifecycle:

• Post-machining
• Pre-shipping
• During storage
• Between manufacturing steps

These fluids can be oil-based, water-dilutable, or solvent-based, depending on the application. Many modern options, like FERROCOTE® 5856 BF, are barium-free to meet evolving health, safety, and environmental standards.

Corrosion can lead to costly part failure, safety concerns, and rejected components. Using the right protection fluid helps:

• Maintain product quality and appearance
• Ensure readiness for final assembly or coating
• Reduce rework and scrap rates
• Protect parts during international or long-term storage

Whether you're protecting a pallet of castings or individual CNC-machined parts, corrosion preventatives are essential.

FERROCOTE® 5856 BF is a barium-free corrosion preventative that delivers up to 5 years of indoor protection. It's designed to protect a wide range of metal parts used in automotive, industrial equipment, aerospace, and more.

• Barium-free formulation for improved safety and compliance
• Excellent rust and corrosion protection
• Water-displacing to eliminate fingerprint corrosion
• Safe for ferrous and non-ferrous metals (including aluminum)
• Used by OEMs like Caterpillar and major automotive suppliers

Metal protection fluids like FERROCOTE® 5856 BF are used across many sectors:

Industries:

• Automotive (OEMs, Tier 1 & Tier 2 suppliers)
• Heavy machinery (construction, mining)
• Aerospace and defense
• Metal stamping and fabrication
• Export and marine shipping

Components:

• Precision-machined parts
• Sheet metal and coils
• Gears, castings, and forgings
• Tools and dies

Fluids can be applied via dip, spray, or brush, depending on your workflow and volume.

Traditional corrosion preventatives often contained barium — a substance now flagged for potential health and environmental risks. Modern fluids like FERROCOTE® 5856 BF offer:

• Safer handling and disposal
• Easier regulatory compliance (especially REACH and RoHS)
• Cleaner performance without compromising protection

FERROCOTE® 5856 BF is more than just a rust preventative — it’s a category-leading metal protection fluid that combines durability, application flexibility, and environmental responsibility.

If you're looking for a corrosion preventative that delivers peace of mind across shipping, storage, and shop-floor operations, FERROCOTE® 5856 BF is the proven choice.

·        Fire Resistant: Fluids that resist ignition and burn slowly under extreme conditions.

·        Flame Retardant: Additives in the fluid reduce flame spread but may not prevent ignition.

·        Fire Proof: Implies a material cannot burn at all—this is not achievable with hydraulic fluids.

Fire-resistant fluids offer the best practical protection by combining safety and performance.
