When discussing aluminum anodizing, one of the most important, and often underestimated, aspects is the sealing phase of the anodic layer. It is precisely this phase that determines the corrosion resistance, color stability, and treatment durability.

One of the most common questions we receive from those approaching a technical surface treatment for the first time is:
“How much does it cost per kilo?”
Whether we’re talking about electroless nickel plating or anodizing, the correct answer is: it depends.
Clean energy has become a top priority for governments and industries around the world, as reducing greenhouse gas emissions has become critical to limiting the impact of climate change. In this context, hydrogen is emerging as a promising clean energy source for vehicles and beyond.

The hard anodizing of aluminum is a process that allows creating a layer of aluminum oxide on the material’s surface with hardness and wear resistance properties superior to those of natural or architectural anodizing.

Anodizing (also known as anodic oxidation) is an electrochemical process that produces a compact oxide layer on the metal surface of the treated part. This process uses electric current and its name comes from the fact that the part to be treated is connected to the anode of an electrolytic cell.

After the fall of the Berlin Wall, several Russian technologies were investigated by the western world in the early 90s to assess their industrial applicability. These technologies came from Russian space and military research. Among the surface treatments for metals, electrolytic treatments called Plasma Electrolytic Oxidation PEO, also known as Micro-Arc Oxidation MAO, gained a certain amount of interest, they made it possible to create an extremely hard and compact oxide layer on aluminium , magnesium and titanium using high-voltage current.

aluminium anodizing, also known as anodic oxidation, is an electrolytic process by which a layer of aluminium oxide is formed on the surface of the workpiece to be treated, giving it excellent surface characteristics.

Aluminum is a metal widely used for the production of items that come into contact with food. Pots, pans, utensils, trays and foil are made of aluminum. Aluminum objects that come into contact with food are often protected through painting or anodizing.

With the online calculator presented below, you can determine the dimensional
tolerances of shafts and holes.
This tool takes into consideration the coatings applied to mechanical parts,
allowing you to calculate the dimensional tolerances needed in mechanical
pre-treatment machining, in order to ensure the correct tolerance of the
finished piece after surface treatment.
