What is the anti-rust performance of cutting fluids used in aluminum and aluminum alloy machining? Can this cutting fluid be used to process steel parts? why?
The aluminum alloy cutting fluid used in the aluminum alloy cutting process is limited by the special influence of the aluminum alloy material to the cutting fluid. First, the aluminum alloy is most easily oxidized under alkaline conditions, and the color will become black, yellow, whitish, and even mildew, etc., so the ph value of the aluminum alloy cutting fluid is weakly alkaline or even acidic, but acidic. In the environment, production equipment processing centers, CNC lathes, etc. are prone to rust, and the working fluid is likely to become a hotbed for bacterial growth. Therefore, aluminum alloy cutting fluids for processing aluminum and aluminum alloys are preferred for weakly alkaline products.
The anti-rust requirement of ferrous metal steel parts is weak and alkaline, that is, the ph is controlled at about 9. When the ph value of the aluminum alloy cutting fluid is lower than 8, the anti-rust performance of the aluminum alloy cutting fluid on the ferrous metal steel parts is relatively poor. Therefore, the ph value of the aluminum alloy cutting fluid can neither be too high nor too low. The lower the ph value, the worse the rust prevention effect of the steel parts. The higher the ph value of the aluminum alloy cutting fluid, the better the rust prevention effect on the steel parts.
The aluminum alloy cutting fluid has poor rust resistance to steel parts, but the aluminum alloy cutting fluid must meet the rust prevention period of about 7 days between the general process of steel parts. Atwell-4100 general aluminum alloy cutting fluid is suitable for processing steel, copper, aluminum, Magnesium is almost all metal products.
