Why Aluminum Flashlight Needs The Second Stage Oxidation Treatment

Why Aluminum Flashlight Needs The Second Stage Oxidation Treatment



Oxidation procedure is imperative to metal materials, for example, aluminum, iron, and so on.. In the flashlight, the aluminum amalgam shell likewise needs the second-organize oxidation process. Why? What part does second stage oxidation treatment play on flashlight? This article will share you a few tips.

You might know something from the aluminum flashlight dealers. When you are picking flashlights, the vendor might let you know the shell has been treated with the second-arrange oxidation process which make the shell difficult to get scratched and get to be harder than that has not been dealt with. Indeed, this has expressed the principle advantage of the second-arrange oxidation, yet did not let you know why the flashlight shell needs it.

“Oxidation process” is a surface treatment way in the aluminum industry. Since both aluminum and its alloys are active in terms of chemical properties, which determines they are easy to get rusty. The second-stage oxidation is to make them not easy to get rusty, and another important benefit is, oxidation can bring an exquisite appearance to the surface.

Entirely talking, the “oxidation” has little to do with the robustness yet can make the surface difficult to get scratched. What decides the hardness is the material itself, for instance, aluminum or compounds, what sort of aluminum, and so on. The immaculate aluminum is of low hardness. At that point heat treatment of aluminum is called “Aging” inline. It heats the aluminum to 380-500 degrees Celsius, keep the stage a while and after that let it cool actually so to build the hardness. The supposed hard oxidation procedure is somewhat surface treatment innovation, obviously, it can just enhance the scraped area hardness unbending nature yet not expand strength.

If a piece of aluminum is not treated, its surface will generate a piece of oxide film, thin, colorless and not abrasion resistant. Common oxidation process is to electrify the electronic cell to generate an oxide layer which is under control, the thickness can be controlled by the current density and time, there are a lot of benefits than the natural oxide layer, wear-resistant, non-conductive. You can dye (generally black or any color) hard oxygen processing, technology and general principle similar oxygen, but a low temperature and low current density, long time, special electrolyte it can get denser and thicker oxide layer with higher hardness.

The problem is, there is no distinct line between general oxidation and hard oxidation, so the US military developed a standard HAII, the third-stage hard oxidation, but many manufacturers do not strictly in accordance with the standards of production. No matter what oxidation process the flashlight adopts, the goal is to protect the shell not easy to be scratched or get rusty and gain a beautiful appearance.

Above are reasons why Tank007 aluminum flashlight uses the second stage oxidation treatment. Are you clear?
