Magnesium Alloy Dedicated Cutting Fluid KR-C8799: Prevent Discoloration, Resistant to Hard Water

Magnesium Alloy Dedicated Cutting Fluid KR-C8799: Prevent Discoloration, Resistant to Hard Water

When new energy vehicles are obsessed with every gram to improve range, and when aerospace vehicles strive for every ounce to push performance limits, a lightweight revolution is sweeping the global manufacturing industry with unprecedented depth and breadth. In this competition that determines future competitiveness, magnesium alloys — “21st-century green engineering materials” with only 2/3 the density of aluminum and 1/4 that of steel — are moving from behind the scenes to the forefront, becoming a key solution to the lightweight challenge.

However, transforming the potential of magnesium alloys into reliable products is challenging. During machining, the reactive chemical properties of magnesium alloys present four core difficulties:

  • Corrosion and discoloration
  • High temperature and tool sticking
  • Cleaning and chip removal
  • System stability and safety

As a “Green Industrial Medium System Solution Provider,” Kerun (科润) deeply understands that solving these systemic issues requires targeted professional solutions. Therefore, we launched KR-C8799 high-performance metalworking fluid — a cutting fluid specially designed for magnesium alloy machining, aimed at precisely and stably addressing the industry’s pain points.

01. Exceptional Protection, Focused on Magnesium Alloy Machining
With excellent corrosion inhibition, it not only effectively prevents surface discoloration of magnesium alloy workpieces like AZ91D and AZ31B during machining and chip removal but also suppresses hydrogen evolution throughout the process, enhancing machining safety at the source. Even at low concentrations, it maintains superior protective performance.

02. Outstanding Hard Water Resistance, No Emulsion Breaking or Soap Precipitation
It possesses excellent resistance to hard water, remaining stable even when water hardness increases, without breaking the emulsion or forming soap scum, avoiding machine tool scaling. Its superior resistance to miscellaneous oils allows easy removal of floating oil in the machine sump, effectively preventing oil interference and keeping the sump fluid clean over time.

Additionally, within the recommended water hardness range, the product maintains low foam characteristics, ensuring that the lubrication and cooling performance of the cutting fluid are fully delivered, guaranteeing clear visibility during machining and stable processing.

03. Safe and Environmentally Friendly
The product contains no harmful substances such as chlorinated paraffin, nitrites, or organic phenols, making it safer to use. It also has excellent biodegradability, is environmentally friendly, reduces the burden of subsequent treatment, and aligns with sustainable manufacturing concepts.

04. Also Protects Aluminum
KR-C8799 not only performs excellently in magnesium alloy machining but also provides superior protection for aluminum and aluminum alloy workpieces. During aluminum machining, it effectively inhibits surface oxidation and discoloration, ensuring machining quality and finished appearance while maintaining low foam and stable lubrication and cooling, making it suitable for processing both magnesium and aluminum materials.

Typical Applications

KR-C8799 is designed for turning, drilling, boring, and milling of commonly used magnesium alloys such as AZ91D and AZ31B in the automotive, aerospace, aviation, and 3C electronics industries.
