When the copper or lightweight light weight aluminum alloy parts are stained immediately after using normal drinking water-undefineddependent reducing liquid, the key reason is the parts of the minimizing liquid react with copper and aluminium alloy, triggering corrosion of your own light weight aluminum alloy or copper. china aluminum parts，It can be strongly recommended to change the reducing substance or set copper and aluminium alloy anti-tarnishing broker agents before processing aluminium alloy sections.

For that reason, to make the lightweight aluminum alloy sections manufactured by cnc be fantastic and also have really good productivity, it is really necessary to use excellent-undefinedhigh-quality lubricating reducing compound. The workpiece packaged by higher-undefinedtop quality slicing drinking water works extremely well quite quite a while without discoloration and constant looks.
