About anodizing before and after treatment for the hardware industry

  • 7 July,2018


Anodizing is an essential part of the hardware industry, after the treatment of hardware will be more durable than the original. But many people do not know what is needed before anodizing of metals and what is anodic oxidation? So today we're going to tell you what happens after anodization.


Anodized aluminium will have a thicker film than the natural oxide film, and the manufactured film will have to be sealed so that the tiny pores on the surface of aluminium will not be oxidized. In this way, only one color of aluminum can become colorful. In fact, not only aluminum can be anodized, but also copper, zinc, steel and magnesium alloys can be treated in industry.


The treatment effect of anodizing can be generally divided into the following:


1. Wear-resisting

Some metal components are often rubbed so that sulfuric acid can be used to adjust the anodizing process so that a thick hard surface film can be obtained. Usually we also add a little oil to the surface layer so that our surface film won't drop easily even in friction.


2. Anti-corrosion

Oxide films obtained from oxalic acid solutions or other solutions have a good corrosion resistance process, such as electric kettle, washing machine tank and so on, which are all oxidized.


3. Architecture

After the invention of aluminum alloy electrolytic coloring technology, the demand for aluminum materials for our buildings has gradually increased. This kind of pre-anodizing coloring additive can be used to make champagne series, imitation steel, bronze, black and other colors suitable for buildings, with emphasis on wear resistance. The performance is better than that of the conventional anodic treatment, and the service life can be up to 20 years in general.
