Alocrom 1200 It is completely free of Chromium (VI), is REACH, RoHS, ELV and WEEE compliant and contains no chromium or other heavy metals. Alocrom 1200 must not be used to treat foodstuff containers as it contains Hexavalent chromium.

What is alodine made of?

Its ingredients include chromium(IV) oxide, barium nitrate, sodium silicofluoride and ferricyanide. In the aluminum industry, the process is also called chemical film or yellow iridite, Commercial trademarked names include Iridite and Bonderite (formerly known as Alodine, or Alocrom in the UK).

A. Iridite is a trade name for a whole family of chromate conversion coatings. Alodine 1200S is the trade name for aluminum chromate that meets MIL-C-5541. Iridite 14-2 is the particular trade name for a product that is chromate conversion for aluminum.

What is yellow chromating?

Yellow chromate is a chemical conversion coating that is applied over zinc plating during the surface coating process. Zinc plating is a soft, ductile, marginally solderable, corrosion-resistant finish. It protects the substrate and corrodes before the base metal, unlike most other commonly plated metals.

What is chromium hexavalent?

Chromium is an odorless and tasteless metallic element that is found in the earth’s crust. It is also found in air, water, soil, and food. Hexavalent chromium compounds are a group of chemicals that have useful properties, such as corrosion resistance, durability, and hardness.

Is alodine 1200 RoHS compliant?

The following is an e-mail response directly from Henkel which would include Alodine 1200. “Our Alodines listed on the QPL-81706 are not RoHS because they contain chrome. We do offer the Alodine 5200 and the 5700 that are RoHS compliant.

Is alodine RoHS compliant?

We offer Mil-Spec and RoHS compliant chemical films. RoHS compliance is achieved by using trivalent chromate chemistry (as opposed to hexavalent chromate chemistry). Hexavalent chromate produces the gold color associated with gold alodine. Our hexavalent chemical films are offered in both clear and gold color.

What is the difference between alodine and Alocrom?

Alocrom 1200 is marketed under the name Alodine 1200 outside of the UK and drawings calling for Alodine 1200 can be coated with Alocrom 1200 and vice versa. … For example, for maximum electrical conductivity, the coating is colourless to very light yellow, whereas for maximum corrosion protection it is a deeper yellow.

How do you apply Alocrom 1200?

For large scale continuous production, Alocrom 1200 may be applied in a conventional spray washing plant. For brush application use only Brush Alocrom 1200 liquid. This product is supplied as a two pack product.

Is zinc chromate hexavalent chromium?

The substance of concern with regard to chromate conversion coatings on zinc plating and RoHS compliance is hexavalent chromium. The RoHS Directive restricts hexavalent chromium, but does not restrict less hazardous trivalent chromium.

Is alodine electrically conductive?

In addition to electrical conductivity, Alodine coatings offer thermal conductivity and are used in applications such as heat sinks. Chromate conversion coatings such as Alodine are an effective solution for aluminum alloys when both corrosion resistance and conductivity are important.

What color is MIL DTL 5541 3?

This film typically appears to be gold or brown in color, but in some cases may be optionally specified as having no color (Having no color is described as “clear”). Type 2: Addresses compositions containing no hexavalent chromium.

Can you use alodine on magnesium?

Alodine 5200 is a chrome-free and environmentally friendly conversion coating. This coating is commonly used on castings, forgings, wrought alloys of aluminum, magnesium, and titanium. The Alodine 5200 process is approved for military applications by the Department of Defense.

Can you alodine titanium?

Titanium can be anodized. See, for example, AMS 2488 [affil. … It certainly isn’t aluminum or any non-ferrous metal, so we simply assumed that it had to be steel or titanium. Whatever the case, they are anodizing it and not using Alodine/primer coating.

Is yellow zinc RoHS compliant?

Only trivalent yellow zinc plating is compliant to the Restriction of Hazardous Substances (RoHS) directive, which bans the use of certain substances such as the carcinogenic*, hexavalent chromium (used in the hexavalent yellow plating process), due to health and environmental concerns.

Is chromate the same as chromium?

Chromium and chromate are different compounds. Chromium is represented as Cr and chromate is represented as CrO42-.

What does yellow passivated mean?

Yellow passivate (trivalent chromium) Yellow passivate offers a better corrosion resistance and is more often used for motor parts and general parts to be used outdoors.

What products contain hexavalent chromium?

Industrial uses of hexavalent chromium compounds include chromate pigments in dyes, paints, inks, and plastics; chromates added as anticorrosive agents to paints, primers, and other surface coatings; and chromic acid electroplated onto metal parts to provide a decorative or protective coating.

What color is hexavalent chromium?

What is hexavalent chromium? Chromium is a lustrous, brittle, hard metal. Its colour is silver-grey and it can be highly polished. It does not tarnish in air, when heated it burns and forms the green chromic oxide.

Where can hexavalent chromium be found?

Hexavalent chromium is a form of the metallic element chromium. Chromium is a naturally occurring element found in rocks, animals, plants, soil, and volcanic dust and gases.

Is nitric passivation RoHS compliant?

Regarding Passivation: Some of our passivate baths contain dichromate, which is not RoHS compliant. … Alternatively, we offer numerous passivate baths that do not contain dichromate, and are therefore RoHS compliant whether or not entrapment is an issue: Citric Passivate, Passivate 6, and Passivate Nitric 2.

Is anodized aluminum RoHS compliant?

While a metal itself does not contain hexavalent chrome, there are anodizing processes and conversion coating processes available that leave it hexavalent-free and RoHS compliant.

Is clear alodine RoHS compliant?

H&E Plating Canada offers ROHS compliant “clear” non chromium conversion coating for your aluminum product. This chemical conversion process is available in both rack and barrel processing.

Is gold Iridite RoHS compliant?
