How To Anodize Aluminum Blue

I am a chinese, i work in a trading company, i am dealing a project which all part are make of adc12(a type die casting aluminium), and the customer ask us to anodize the part with blue color, but our supplier, a metal stamping factory , told me their supplier can't anodize the adc12 with blue col Anodizing again might look complex, however, the steps are straightforward.

How to anodize aluminum blue. In order to properly anodize aluminum parts, the surface must first be cleaned and rinsed before getting placed into a bath of an electrolytic solution, primarily either sulfuric or chromic acid. The anodizing solution that is most often used for anodizing aluminum is sulfuric acid. The aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized.

The aluminum can also be dyed at the end of the anodizing process to get a cosmetic, colored finish. Next, we seal the anodize simply by rinsing it with water or other chemicals, depending upon your needs. The purpose of anodizing is to form a layer of aluminum oxide (higher corrosion and abrasion resistance than aluminum) that will protect the aluminum beneath it.

The second step is that the aluminum part acts as the anode, then it is submerged in an electrolytic solution bath along with a cathode. This is done through a secondary operation with either an organic or inorganic coloring. Below are two images zooming in on the surface of the anodized metal.

Below are the general steps used in the anodizing process. A ventilated area to work in Anodized finishes have made aluminum one of the most respected and widely used materials today in the production of thousands of consumer, commercial and industrial products.

Unlike paint, which can flake off if not applied properly, anodized finishes are actually formed from the original material. Aluminum anodize coating thickness penetrates 50% into the surface of the substrate. How the process of anodizing aluminum works.

It can be a pale grayish blue if you do a shorter anodizing cycle. This is important for the removal of impurities that can hinder the process. Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium.

They contain enough degreaser, deoxidizer, and sealer to anodize 100 square feet of aluminum surfaces. The anodizing is a porous structure that grows out of the base aluminum and absorbs colored dye very well. Don't let it touch the aluminium part at the anode.

This provides a electrically conductive coating that contains a number of positive and negative ions. A cathode is mounted to the inside of the anodizing tank; Place a lead cathode in the bath.

Before beginning the process, one should calculate the liters or gallons of solution needed, while taking into account the recommended ratio of acid in the anodizing bath (15% to 18%). This is what you need to anodize aluminum: There are some types of anodizing that produces a porous oxide layer that can be colored with dyes or.

Anoplate processes black, blue, red, gold, as well as small lots of green and gray using standard organic dyes. But the characteristics of that film will vary. Attach the positive connection of your power supply to the aluminium anode and the negative connection to the lead cathode.

Oh, and i'm trying to anodize 7075 aluminum, without any color added. This should have a surface area of at least twice that of the aluminium part. To be more specific, anodizing creates an oxide layer that has roughly one million microscopic pores on the surface of.

Each step requires an external heat source (not included). Aluminum casting alloys containing relatively low amounts of silicon and iron and higher amounts of magnesium, chrome, and zinc tend to anodize well. About 0.0001 of aluminum is consumed in building an anodized coating of 0.0002.

How to anodize adc12 material with blue color? An agitator (optional) safety gear; The hard anodized coating gives it better resistance to abrasion and corrosion than other coated aluminums.

First, cleaning of the aluminum part occurs before undergoing anodization. Dye (only needed if you want to make it a different color) aluminum or titanium wire; A power source with connections;

The electricity in the anodizing process makes the metal porous, thereby preparing it to receive dye. It is not intended for use on any other metals or materials. Our versatile anodized aluminum can be diamond, laser or rotary engraved.
