What is the difference between alodine 600 and 1200?
This is class is commonly recognized as Alodine 1200. Class 3 is a thin film coating typically used in electrical bond applications, commonly recognized as Alodine 600. The only difference between the two classes is the coating thickness, which is determined by immersion time, therefore the same chemicals are used.

How long does alodine last?
Alodining is a process in which a metal is coated with a chemical called alodine. This coating hardens to the surface and can last for years if painted, not requiring reapplication.
Does alodine add thickness?
Aluminum chromate conversion coating/alodine produces a thin coating in the range of 0.00001-0.00004 inches (0.25-1.0 µm) in thickness. Chemical conversion coatings on aluminum are amorphous in structure with a gel-like composition hydrated with water.
What color is alodine?
Alodine is a slightly cheaper process than anodizing, though it is more prone to scratches, wear, and cosmetic damage. The most common color of the coating is an iridescent greenish-gold, and thus it may also be used for cosmetic purposes.

Does alodine prevent corrosion?
Alodine is a chemical treatment of aluminum to prevent corrosion, it is electrically conductive and can be used as a primer for layers of paint. It does not add weight or changes dimensions of the part that is being treated, where as paint does.
What is the difference between alodine and anodize?
The primary difference between Alodine (chem film) and anodizing is that anodizing is an electrolytic process and Alodine (chem film) is not. Alodine (chem film) and anodizing are both processes used in aluminum finishing to improve corrosion resistance. Both transform the outer layer of the surface of the metal.

What is the difference between the 1200 and 600?
The chemistry difference between the two is that the 600 has some "complex cyanides" in it that the 1200/1200S doesn't - more environmentally unfriendly. The 600 - in either Class 3 or 1A can be sprayed, dipped or brushed. The 1200 can be sprayed, dipped, or brushed in only Class 1 work - Class 3 work must be dipped.

Is Alodine 600 hexavalent?
Another thing to note, though, is that the Alodine 600 and Alodine 1200 mentioned on these pages are hexavalent and not RoHS-compatible. You may want to contact Henkel or another vendor about a more eco-friendly trivalent chromate product.
Is Alodine 1200 the same as 600?
Mr Budman is correct in his answer about the concentrations of both chemicals. But both can be used in Spray or Immersion applications. The primary difference in the two chemicals is the issue of coating weight. The Alodine 1200 will produce a heavier film than the 600 will. The Aerospace industry uses the 600 chemical on areas that require electrical bonding.
Can you use #600 in spray?
The differences seen are that the #600 can be applied by an immersion dip, while the #1200 is applied by spray. A toner is used with the #600 and not with the 1200S I hope this helps. Mr Budman is correct in his answer about the concentrations of both chemicals. But both can be used in Spray or Immersion applications.
Is alodine a trade name?
A. Hi Roger. Alodine is a tradename for Henkel products and they are free to change the formulation, the operating parameters , or anything else at any time. Thus, although it can be interesting to get general impressions from users, we should not rely on years-old postings for operating parameters! Please request a current technical data sheet from Henkel. Good luck.
Alochrom 1200 vs. Alodine 1201
Q. When ordering Alodine 1201 [linked by editor to info/product on Amazon] for surface treating aluminium aircraft components, my organisation was supplied Alocrom 1200 with a claim that they are the same thing. I am not sure that this is so.
Can I use Alodine 1201 instead of 1200
Q. The manual I am using is calling for use of Alodine 1200 or equivalent. I have a lot of Alodine 1201 [linked by editor to info/product on Amazon] . Could I use the 1201?
What is alodine used for?
Aside from passivating aluminum, alodine is also useful as a base for paint coatings and priming, as well as preserving electrical conductivity. Application of alodine finish is typically by dipping, brushing, or spraying of the precision machined part.
What is the process of alodine coating?
The defining principle of Alodine aluminum finish is the electrochemical reaction of chromate. The Alodine coating process is actually a quite simple chemical process . Aluminum coatings are usually created through passivation, which makes the coated metal surfaces chemically inert.
How long does it take to apply alodine?
The application process of the alodine coat usually lasts mere minutes. The exact time depends on the method in use. Generally, immersion in a chemical bath will not last more than an hour at the utmost.
Can you use alodine film at room temperature?
Manufacturers can apply Alodine films at room temperatures. The implication of this is that parts manufacturers don’t have to stress too much during manufacturing, which is a very desirable property, particularly in precision machining parts. Also, the energy demands of the process are low, as well as the pollution impact on the environment, especially the later forms of alodine coatings.
Is aluminum anodized?
Aside from alodine coating, anodizing layers are also great ways of protecting aluminum surfaces from corrosion and rust. However, one of the ways alodine aluminum coatings are different is the thinness of the film, which is usually between 0.5 and 4 microns. The film is also soft, porous, has good adsorption properties, and will not alter the part size, justifying its use as base layers for paints.
Is alodine safe to use?
Although alodine is generally safe and doesn’t pollute the environment , it can be quite toxic to the skin. Therefore, it must be very carefully handled and disposed of after use. In fact, the use of some types of alodine coatings is regulated by government bodies.
