What does Iridite coating do?

What does Iridite coating do?

Iridite is a N.C.P. (non-chrome chemical process) that produces a protective chromate conversion film coating on aluminium and its alloys. It is often used as a protective coating for abraded anodized surfaces and to provide an electrical contact.

What is Iridite NCP?

Iridite NCP is an innovative new process that offers extremely high resistance to corrosion, tested to 1000 hours on many aluminium alloys. For new chrome free technology that meets all environmental standards, bare corrosion resistance without painting, even after heating or baking.

What is gold Iridite?

2007. To add to what Ted said, Iridite is a trade name for a line of chromate conversion coatings. Yellow Iridite is sometimes used as a general name for yellow conversion coatings on a variety of substrates (zinc, cadmium, aluminum, etc).

What color is Iridite?

Alodine used to go to an old gold color on the high end, while Iridite tends to be slightly more of a reddish brown.It is possible to get the same color out of either, but it takes some work.

Does zinc chromate contain hexavalent chromium?

PennEngineering uses the detection methods defined in the IEC-63321-7-1:2015 to measure hexavalent chrome in the chromate conversion (passivation) layer of our zinc-chromate plated parts to assure they are not hexavalent chromium based as determined by IEC-62321-7-1:2015 and other consensus standards.

What is the formula of aluminum chromate?

Al2 CrO4 3
The formula for aluminum chromate is Al2 CrO4 3, so there are 12 oxygen atoms.

Is SurTec 650 conductive?

SurTec 650 is a trivalent chromium compound for the surface treatment of aluminium, achieved through a dipping process. The treatment is electrically conductive and an excellent pretreatment prior to powder coating. The process complies with the corrosion requirements of MIL-DTL-81706-B and F-MIL5541.

Is Iridite NCP conductive?

Iridite NCP is able to operate at high temperatures up to 350 degrees Celsius and unlike chromate conversions requires no oven curing time. Iridite NCP offers a good level of electrical conductivity which is comparable to conventional chromate coatings and is often used on applications involving Electrical grounding.

Can aluminum be anodized?

Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel.

Is Iridite the same as chromate?

Commonly known as Yellow and Clear Iridite or Alodine finishes, chemical conversion coatings are used primarily for paint adhesion on aluminum.

What is alodine1200?

Alodine* 1200S is a powdered chemical, used for producing paint bonding, corrosion resisting coatings on aluminium and its alloys by either spray or dip processing. The same concentration of Alodine 1200S is normally used for both spray and immersion processes.

Can you use chromium coating to protect copper in place of zinc?

Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys. The coating has a complex composition including chromium salts, and a complex structure.
