Need to know anodising cost

A. Cost varies greatly. Just a few factors are competition, chemical costs, waste disposal costs, employee cost, real estate cost and quality of employees. Size makes a big difference -- generally bigger costs more than a cost per sq foot scale up. Certifications cost more. Amount of parts processed in a day. All the same parts, or a wide variety of sizes and shapes. Some alloys anodize easier than others. Dye cost varies greatly by fade resistance, color and type of dye used to make it(organic or organo-metallic). Cast is a total pain to anodize. Extruded can be better and 100% machined wrought alloy is the easiest.
Is masking required? When racked, will it cup and drag out great amounts of your chemicals.

This is a tiny amount of factors that you have to set before you can ever think of having a semi-valid answer.

A. Hello Nicole,
Good day! How are you?
It is very difficult to say exact price for the anodizing process. Here in Bangalore (INDIA) from one of the anodizing industry I got 3 anodized components for Rs. 150.00. Dimension of each are 64 mm x 62 mm x 75 mm, 64 mm x 62 mm x 20 mm and 64 mm x 62 mm x 2 mm.Total quantity was 5 sets.
I feel 6063 He9 and 6351 He30 T6 would be better option for anodizing. Anodizing quality depends on silicon content in the alloy (should be low).

A. That all depends on the market and the specifications. True MIL spec type 3 is expensive because of the cooling requirement.
Next, there is nothing to prevent the current competition from lowering their prices. They can break even a lower cost than you can, in almost all cases. And, they may do it at a loss to drive you out of business.
Real MIL spec type 3 with all of the required testing and controls could easily run 10 times as much as thin type 2 that is non spec.
What you need to do is to figure out how much it will cost you do do the job and then find out what the competition charges. Then cross your fingers that they do not lower their prices.
