Link to the Anodizing calculator:

Tips:
1. Make sure you have a solid electrical connection to part
2. Pay attention to the temp – never go over 75deg. Ideal is 68-70deg.
3. Mix all solutions w/ DI or Reverse Osmosis water
4. Clean parts before etching in dilute simple green or dish soap.
5. Etch for 30 secs to 2 minutes. The longer you go the more matte finish you’ll get.
6. Hang parts in acid bath and start anodizing. Always 15v. Current varies on surface area of part.
7. Make sure ea part is bubbling, if you dont see bubbles it’s not anodizing.

Hello Everyone, I have a problem with anodising the pressure casting aluminium, means the alloy with high silicon contain (Si>6%). Does anybody tried this? Which parameter could be a problem, which should be combined?

Solution concentration and contents, the specific composition or impurities due to the makeup of the substrate alloy all factor in the oxidation or substrate surface conversion rate depth and crystalline structure effecting the results, keep impeccable notes about everything from room temp, ambient air quality, distilled water PH, contaminants, conductor length (Volts Amps Ohms) solution composition concentration temperature before and monitored during electrification compare all electrical circuit discrepancies at applicable time intervals, if the solution temp is up and you notice a voltage drop your solution has a high metallic content and will draw more current heat up the bath and the loss of pressure (volts) is either due to increased flow (amps) or reduced conductivity (low temp and high ohms) you know, all kinds of variables!!

Has anyone, through trial and error, found the best solution for durability? Not for shine and gloss but for being really hard to rub off and wear out, like bike clutch and brake levers that must suffer through prolonged frictional contact and stay put for years.

You should have made clear that PH down is acidic and how acid plays its part in the process. The world is full of idiots but they all seen to know what acid is.

So are you suggesting to ignore running constant current like most suggest and just run in CV at 15v even though the amps would be right down ?

I’ve been running requires amps to surface area but my volts are then higher in the 30v range to get the correct ampage.

Any ideas please , they do take the dye but I’ve been getting a dull not very deep dyed surface.

Thanks

Wonder if you can help me , when I use the 720 rule for area ,
I set the amps running in CC mode yet my volts still increase to around 25v-30v yet I read they should roughly be around 15v
Any help would be appreciated thanks

Sorry to bother again! I did my setup without the air hose. I used a gallon of water which came out to about 3.5 cups of Ph Down. Is the Ph Down supposed to dissolve ? It's all pretty much all sitting at the bottom. Thanks!

Did you mix two different colors ? It looks like the bottle is labeled "violet 3d + 1/3 blue" Which blue did you use and can you confirm ratio ? Thanks

It's a good idea to present the process in this way. Our company has always been cooperating with Galuminium in the past few years. It manufactured many aluminium products like the aluminium extrusion, aluminium window, aluminium door, aluminum curtain wall, etc.

Great process! Question- I want to anodize freshly sanded and cleaned aluminum (to give it a durable finish) and NOT do the dying part. Could I skip the etching and dying steps, and just do the anodizing step in the sulphuric acid? Thanks!

hello
i find a used current adjustable power supply 2000 watts from 12 volts to 26 volts / from 0 amperes to 80 amperes , i want to ask you if this power supply can do the job…for small and larger pieces of aluminium. this power supply start from 12 volts , did starting with 12 volts , this can mess up small parts ??
thanks
