For Aluminum Precision Machining parts, Aluminum alloy parts machining, how could we clean the stains on the surface of aluminum alloy parts? Let's have a look into it:

1. A small amount of aluminum alloy parts can be washed with cola, which can be washed very cleanly. This method can also be used for washing floors and tiles. For example, we can clean the aluminum windows and toilets in our house with Coke.

2. Aluminum is a very active metal, and its surface is prone to chemical reactions. However, the surface of aluminum alloy parts can combine with oxygen in the air to form a dense oxide film. This dense oxide film has a good protective effect on the interior of aluminum, so that it will no longer be corroded in the air. During various heat treatment, machining, transportation and storage processes, the surface of aluminum alloy parts will inevitably be oxidized, forming an oxide layer with uneven thickness.

At the same time, aluminum alloy parts are also easily contaminated by various greases and absorb some other impurities. Like some adsorbents, thinner oxide layers can be cleaned with a solvent, chemically and mechanically treated sequentially, or chemically treated directly.
For severely oxidized metal surfaces, if the oxide layer is thick and cannot be cleaned directly, chemical treatment is performed with a solvent, but it is better to perform mechanical treatment first.
3. Use the aluminum alloy degreasing cleaning solution. Because the alkali solution has a strong corrosive effect on the aluminum alloy, and the organic solvent is expensive, when there are many aluminum alloy parts that need to be processed and cleaned, the aluminum alloy cleaning solution can be prepared for cleaning.

For other steel material products like Brass Precision Machining , Steel Precision Machining , Titanium Precision Machining ,etc, it may also have similar problems after machining, but we can have many ways to deal with it. For more information, welcome you to contact me: sandy@sczyltd.com
