How Can Machining Aerospace Aluminum Components Be Truly Worry-Free?
In the manufacturing of aerospace aluminum parts,
“Worry-Free” = “Solid Technical Strength”
KERUN Metalworking Fluid KR-C8211
Redefining the “worry-free standard” of high-end machining fluids
No worries about corrosion, no stress over tool wear, no fear of unplanned downtime.
1. Exceptional Corrosion Inhibition – Safeguarding Zero-Defect Components
Engineered for machining high-strength 7050/7075 aluminum alloys used in wing spars, landing gear, and other critical aircraft parts.
Provides long-term protection for 7–15 days, effectively preventing corrosion during extended processing cycles and minimizing the need for secondary protection or rework.

2. Upgraded Lubrication with Excellent Machinability
Compatible with machining of high-temperature alloys and titanium alloys (e.g., TC4).
Reduces fluid change frequency and simplifies workshop fluid management, contributing to operational efficiency.

3. Extended Service Life – Confidence in Complex Conditions
Powered by advanced core technology, KR-C8211 offers triple-layer protection for manufacturers: antibacterial defense, production stability, and intelligent foam control—all in one.
① Long-Lasting Antibacterial Action
Formulated with broad-spectrum antimicrobial agents and strong pH retention, it effectively inhibits bacterial and fungal growth, significantly delaying fluid spoilage and odor development.
② Stable Performance in Demanding Environments
Excellent tramp oil separation and hard water resistance. Maintains consistent performance even under oil-leak-prone machinery, hard water conditions, or high workshop temperatures—delivering up to twice the service life of conventional products.
③ Intelligent Foam Control
Proprietary foam-control technology keeps foam volume consistently below 5%, even in high-pressure, high-flow recirculation systems—eliminating the need for shutdowns due to foaming.

— Case Study —
A leading aerospace manufacturer once struggled with insufficient lubrication leading to shortened tool life and excessive foam buildup, requiring frequent production halts for cleaning. After switching to KERUN KR-C8211, they achieved:
✔ 15 consecutive days of machining without adding corrosion inhibitors—zero corrosion on aluminum alloy fixtures.
✔ 6 months of stable fluid use without degradation, resulting in a 25% increase in production line efficiency.
