(KNOWN AS ALODINE 1000L) 1 of 6 INTRODUCTION: BONDERITE M-CR 1000L AERO (known as ALODINE 1000L) is a liquid chemical used to produce a protective coating on aluminum and aluminum alloys. Alodine not only prevents corrosion but also makes a product more durable. The Aerospace industry typically . Type I-Contains Hexavalent Chromium (non RoHS) GOLD. According to their different chemical composition and properties, Alodine coatings can be classified into various types, with the most common being Type 1 and Type 2 according to Type II Alodine Coating Type II does not contain hexavalent chromium. It is commonly referred to as Alodine or Anodize Type 1 Chromic Acid Anodize; AnodizeType 1 B Chromic Acid (Low Voltage) Anodize Type 1 C Non-Chromic Acid; AnodizeType 2 Sulfuric Acid Class 1 (Non-Dyed) AnodizeType 2 Sulfuric Acid Class 2 (Dyed All Colors) Anodize Type 2B Sulfuric Acid Anodize; Anodize Type 3 Class 1 (Non-Dyed) Anodize Type 3 Class 2 (Dyed All Colors; Bright Dip Known as Alodine 1500. Type II are "Compositions containing no hexavalent chromium". MIL-DTL-5541 Type I specifies hexavalent chromium bath while MIL-DTL-5541 Type II is normally achieved with a tri-valent chromium bath. This process uses both the Amchem 6-16 Deox. Hi Mary, In MIL-DTL-5541 [on DLA] conversion coating, "Class" has to do with electrical conductivity (which in turn involves coating weight), but in addition to "Classes" there are also "Types" which have to do with the presence or absence of hexavalent chromium. Durability: Alodine’s oxide layer is strong and long-lasting, shielding the metal surface from damage Alodine, also known as chem film or chemical conversion coating, is a chromate conversion coating used to protect aluminum, magnesium, and other metals from corrosion. Alodine finish je spolehlivá povrchová úprava pro zlepšení materiálových vlastností Removable polymer coatings were evaluated as a means to suppress dehydration of Alodine chromate conversion coatings during thermal aging and thereby retain the corrosion protection afforded by Alodine.

The chromate ions act as oxidizing agents, creating a passive layer that chemically bonds to the metal surface and is responsible for it Types of Alodine Finish. Skip to content. Alodine is a chromate chemical film coating for metals that enhances the part’s corrosion resistance, strength, surface adhesion, etc. Both are used in aluminum finishing to increase the anti-corrosive properties and alter the outer surface of the metal, but they are not the same. MIL-DTL-5541 Standard: Type 1 – Alodine: Type 2 – Alodine: Type of Chromate Film Coating: Hexa-valent Chromate: Tetravalent Chromate Finish (Hex-free) Class 1A (Alodine 1200) Provides superior corrosion resistance. The MIL-DTL-5541 specification (current revision is MIL-DTL-5541F) covers chemfilm (aka alodine or chromate conversion) on various aluminum alloys. These coatings don’t offer the vivid color palette that some other finishes might, but they give aluminum a distinctive and professional appearance. Introduction: Alodine T 5900 RTU treatment is a complex trivalent chromium conversion coating formulated for treating aluminum and its alloys, metals coated with IVD aluminum, magnesium, titanium ALODINE 600 is a powdered chemical used to produce a chromate conversion coating on aluminium and its alloys, which ranges in colour from light, iridescent golden to tan.

Apart from MIL-DTL-5541 Type I and Type II, there are other Alodine finishes like AMS-2473, AMS-C-5541, and others. All these chem films are industrial and serve high importance in increasing the component lifespan. An alodine finish is a type of conversion coating for aluminum parts that creates a thin protective film on the metal that prevents corrosion. Its proper use also reduces worker contact to chromating solutions and waste, such as rinse water generated from a chromating process. MIL-DTL-5541 Class 1A: Types Of Alodine Chromate Conversion Coating. A ready-to-use liquid chromate coating chemical for conversion coating of aluminum and its alloys. Alodine Call Outs. Alodine can also be used as a simple way to touch up damage to an anodized finish. ISO 9001:2015. You’ve probably heard of MIL-DTL-5541. Hi, Bob. In addition to protecting the part, alodine does not add any noticeable weight to an assembly. Unlike passive coatings such as paint or powder coat, conversion coatings involve a chemical reaction at the outer surface of a metal part. It forms a coating that protects the metals and enhances their aesthetic appeal. Class 1A - Maximum corrosion protection - Improves adhesion of paint finish systems - Less conductive Irridite / Alodine. g. What Is Alodine? Alodine is a chemical that dissolves in an aqueous solution to create a gel for metals such as aluminum alloys. However, it is unsafe due to the hexavalent chromium and requires stringent adherence to legal processing and regulations. Other benefits include less– time-consuming, electrical Types of Alodine Finish. The process involves applying a chemical solution that reacts with aluminum to create a durable coating. For both Alodine 600 & 1200, the difference between Types 1A & 3 coatings is primarily a function of application time. Chromate conversion coatings, aka chem film or Alodine™, and anodizing are commonly used on aluminum parts.
