Coolant for machining

rhenus FU 70 W: Best performance with aluminium and steel

The Rhenus Lub GmbH & Co KG has developed a premium product specifically for machining under the toughest operating conditions: rhenus FU 70 W is the name of this innovative water-miscible EP coolant, which enables customers in the metalworking industry to achieve outstanding results, particularly when machining aluminium alloys and steel.

He unites

excellent lubrication performance,
low foaming
and the most modern environmental protection.

Thanks to its unique formulation, rhenus FU 70 W produces very little foam even when used with soft water with a German hardness of between 3 and 10 degrees, ensuring a consistent application of the cooling lubricant at all times.

rhenus FU 70 W is safe for the environment and for people

As well as its outstanding technical qualities, the new lubricant also impresses with its excellent environmental and human safety profile – it is, after all, a premium-class product from Rhenus Lub’s range of amine- and boric acid-free cooling lubricants.

Thanks to its low pH value of 8 to 8.8, rhenus FU 70 W prevents skin irritation whilst meeting the highest standards for Environmental protection and application security.

Everything about rhenus FU 70 W

What rhenus FU 70 W does for your business

„With its excellent lubricating properties, rhenus FU 70 W is the first choice, particularly for customers who machine wrought aluminium alloys and die-cast aluminium with a silicon content of around one per cent,“ explains Stephan Klaue, Product Manager for Rhenus Lub, highlighting the benefits of this high-performance lubricant. „This ensures a clean chip is produced from the relatively soft material, thereby preventing tool wear.“

Soft alloys place the highest demands on the lubricant used, which rhenus FU 70 W meets perfectly. The fluid guarantees optimum lubrication and clean surfaces.

In practice, for example, customers were able to significantly increase machining performance, minimise tool wear, boost production reliability and reduce manufacturing costs when producing valve blocks, aluminium compressors or cylinder housings.

Applications of rhenus FU 70 W

rhenus FU 70 W has also proven its worth in the medical technology sector. Thanks to its excellent technical properties, this high-performance mineral oil-based lubricant is particularly suitable for demanding machining operations involving small internal threads and very fine tools.

rhenus FU 70 W delivers good results when turning, drilling, milling and reaming titanium and stainless steel. The fluid can therefore also be used, for example, in the manufacture of implants or probes.
