Description
Excelfluid AL
A water-mix metalworking fluid designed for the machining of aluminium alloys
Product code: S047
Product Description:
Although the use of aluminium alloys in engineering has increased significantly over recent years, the variety of
alloying materials used and the severity of machining operations employed has increased in complexity more
recently.
More typically, high stock removal rates are employed in finish to size operations. In such environments the cutting
fluid has to withstand high rates of flow and be capable of providing outstanding hydrodynamic lubrication.
Excelfluid AL has been designed with these more recent trends in mind, particularly where machining performance is
critical on the more difficult high silicone alloys. Excelfluid AL is unique in its provision of lubrication in extreme
pressure situations without the use of traditional surface active components. The design approach taken has
produced a product which is particularly suitable for the aerospace industry where inter-granular corrosion is of
concern, whilst providing a fluid which gives maximum protection from staining on high magnesium and copper
alloyed materials.
Fluids providing such levels of performance have traditionally been more susceptible to foam generation in low
hardness waters where associated machining operations demand high coolant flow and pressure. The use of
intrinsically low foaming components ensures that foaming is kept under control even in waters of less than 20 ppm
total hardness.
Application:
Excelfluid AL should not be used at concentrations less than its specified break point.
Maximum machining performance can be achieved at concentrations up to 12% however, the majority of operations
will be completed with concentrations in the range 4 – 10%.
