We know how intimidating it may be to decide if some of the factors contributing to cost are unknown.
In this brief blog, we are to assist you in understanding how major points impact the price of anodizing.

Coating Thickness
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||22px|||” global_colors_info=”{}”]Before we go any further, we should clarify one essential point. In this post, we do not compare offers of different service providers. Their prices may significantly fluctuate, but it does not have anything in common with the standard cost factors of anodizing.
We also do not discuss how ordering a higher or lower quantity affects offers (large-scaled orders often receive discounts). But, we’ll explain how a number of metal parts proceeded in one run, which may affect the final price in the ” racking section.”
So, let’s get down to business. The first factor that determines the price and is usually questioned by the service provided is coating thickness. In other words, the exact width of the coating. This characteristic of anodizing is regulated by applying several layers or using less or more thin and precise methods.
The “basic” coating has the lowest price, which is completely understandable. It is fine in most cases. But what if your specifications require a thinner or thicker coating? You should know that any deviations from the “basic” option will result in an increase in price.
Not only the thickness of coating but also the precision of anodizing impacts the cost. As such, coating, the range of thickness of which is +/-0.001″ (inches), is cheaper than stricter +/-0.0001″. In addition, coating thickness impacts the turnaround time. You should consider it while planning a production cycle.[/et_pb_text][et_pb_text _builder_version=”4.17.4″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||11px|||” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]
Type of Anodizing Process
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||15px|||” global_colors_info=”{}”]We’d like you to know all the types of anodizing that exist to be aware of options that can be offered. However, we cannot provide you with actual costs, but only with assumptions which of the processes are more or less expensive. It is so because we have seen prices for different types of anodizing significantly vary from seller to seller.[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||11px|||” global_colors_info=”{}”]
- Type I or Chromic Acid Anodizing (CAA). Chromic acid provides the thinnest anodizing coat, up to +/-0.0001” However, it is not recommended for aesthetic purposes because it absorbs dyes.
Continued use of chromic is a crucial environmental concern. That is why costs are tightly linked to a particular region’s policy regarding chromic acid. Costs for this process are rather average.

- Boric-Sulfuric Acid Anodizing (BSAA). You may be offered to anodize your parts with boric-sulfuric acid instead of chromic acid. It creates a less precise coating, but it can be used as a paint/prime base. It is also more energy-efficient than the Type I process. Thus, the price for BSAA is most likely lower than for CAA.

- Type II or Sulfuric Acid Anodizing. This process is the most widespread one. It offers great precision, up to +/-0.001”, and great corrosion resistance. It absorbs dyes well and is receptive to other methods of finishing.
The kicker is that sulfuric acid anodizing is less expensive than other anodizing types. It is so because of less heat and power consumption, absence of safety implications, and more affordable acid used.
If you are completely unsure that anodizing would be a good fit for your components, we suggest sulfuric acid anodizing. Unless specifications directly demand something different, of course.
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||9px|||” global_colors_info=”{}”]
- Type III or Hard Anodizing (Hardcoat). This process also exploits sulfuric acid-based electrolytes. However, the coating obtained is much thicker and denser. You would really need hard anodizing if your components were expected to be subject to extreme wear applications.
The good thing is that hard coated parts can be black dyed and have a nice appearance. They are also non-conductive (circumstantial features).
Typically, hard anodize is somewhere between type I and type II anodizing, concerning the price. Unfortunately, you do not have much of a choice if you need superior abrasion and corrosion resistance.

- Titanium Anodizing. This one is attributed to coating titanium parts alone. It is simply the controlled creation of an oxide film on the metal workpieces’ surfaces.
As a matter of fact, other methods of anodizing are suitable, mostly for aluminum. So, one more time, you do not have a broad range of options of how to apply coating on titanium, but this one.
Luckily, it is not that expensive. Additionally, a number of features with which titanium anodizing can enhance the surface, which enables it to compare it to any other type of coating.
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||11px|||” global_colors_info=”{}”]
Dimensions
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||14px|||” global_colors_info=”{}”]This part is easy. Dimensions of parts you need to anodize define the total surface area. In its turn, surface area determines the force of current that must be applied to electrolyte liquid.
Additionally, the surface area affects the number of parts that can be processed in one run. Service providers often care about the total surface way more than about the number of parts.
Here is the scary part. Both racking and tanks for acid have certain limitations. As such, extra small parts cannot be fixed on racks correctly. Alternatively, gigantic components may not just suit standard sizes (or volumes) of tanks.
It is likely that you would eventually find a service provider that has tanks big enough to contain your components. Unfortunately, it would affect the final price for sure. You also should pay more attention to the surface area of your parts rather than their quantities while calculating expenses.[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||11px|||” global_colors_info=”{}”]
Racking
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||14px|||” global_colors_info=”{}”]
By racking, we mean how parts to be anodized are positioned in the tank. This process of coating implies that metal components should be dinked in a tank with electrolyte liquid. For this purpose, they obviously should be held by the equipment that would move them up and down.
Racking or jigging exploits metal racks to expose metal parts to a solution. Typically, service providers use either titanium or aluminum racks. This choice can impact the cost, as the first one is expensive but durable, while the second one is less convenient but more affordable. However, there is nothing you can do about it.
But, there is another way racking influences the final price of anodizing a batch of metal components. The quality of coating directly depends on how many components are sunk into a tank and are exposed to current. The distances between the positions of components on the rack are also crucial for the quality of the process.
The simple truth is, any service provider would load the rack with a maximum number of parts possible unless something particular is requested by a customer. It is not like a pile of your precious details would be simply thrown in a tank if you had not paid more. There are still requirements for power supply, which should be 15 or 30 amps per square foot.
However, if you care for the quality of coating, you may like the idea of requesting the service provider to limit the surface area. Thus, fewer components would be processed in one run. This way, you should not be surprised if the final price differs from the basic one.

Design & Extras
[/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||14px|||” global_colors_info=”{}”]
The thing is, not only the surface but also the design of your components and other extras affects the final price. Let us give you an example.
The coating is basically an additional layer that somewhat changes the original dimensions of a part. It is frequent that your components have precisely drilled holes, which you do not want to deteriorate in dimensions. So, you would request a service provider to do something about it.
For this purpose, holes masking is conducted. Basically, it is the plaguing of all the holes with capes. It is a time and labor-consuming process. And as with any other non-basic option, it will be additionally charged.
