Anodize vs Alodine Alodine, a chemical conversion coating, also known as "chem film," is a thinner conversion coating that is conductive and is commonly used in conjunction with masking in anodized parts. In contrast, anodizing is a thicker coating created by immersion with electrical current. Ch...
Over 50 years experience in aluminum anodizing, both Type II & Type III hard coat anodize. AMS 2469, AMS 2471, AMS 2472, and MILA8625.
Q.My company manufactures a light business jet aircraft. We have some baggage compartment tiedown fittings made by a supplier from 7075-T651 aluminum. Our drawing specifies anodize per MIL-A-8625F Type III, class 2, dyed to a specific color chip per Fed Std 595. The color is supposed to...
Anoplate’s AnoLube III - 15k typically involves 2-mils (50 microns) of coating thickness. Because the anodize is grown from the aluminum substrate, roughly half of that coating thickness penetrates in to the original dimension, so the measurable dimensional change on a 2-mil coating is approx...
Type II & Type III Anodizing Hard anodize for military standards This dielectric surface coating improves abrasion resistance and isexcellent plating for corrosion resistance. It improves the appearance of aluminum. Type II comes in many color selections, and Type III is made to military standards. ...
I am looking for the exact bath solution for what I have been told is a type II anodize per AMS 2488D. I understand that it is >=13 pH and that the temperature is controlled to ±2 F and that voltage is the controlled characteristic, but WHAT is the chemical?
The Same Universal Electrolyte produces both electropolish and hard anodize with power savings of over 50%. The following technical and practical areas relating to heavy thickness anodize will be discussed: 1) New Anodize Bath Parameters, 2) Power Supply Requirements, 3) Tooling and Racking Set-up...
In reality there are many jobs that require seal of Type III Anodize, but it is the decision of the purchaser and not the job shop to make. Call your customer and give them a choice, maximum abrasion resistance or color longevity? Bill Grayson - Santa Cruz, California, USA 2001 publicly...
A. While I'm hesitant to offer the following, because as Ted said - it is very dependent upon your exact circumstance, there is a substantial weight and thickness difference between a MIL-A-8625 type II (conventional) and a MIL-A-8625 type III (hard) anodize coating. Type II has to ...
