New Standards in Corrosion Protection
A customer requested 480 hours of resistance in the salt spray test for EN AW 7075 with a 30 µm hard anodized coating—a significant challenge for this material. At that time, we narrowly missed the mark, but this motivated us to further improve.
The result: An impressive 2016 hours of resistance according to DIN EN ISO 9227. This progress underscores our commitment to durable, innovative solutions.
Our Facts:
Material: EN AW 7075
Coating: 30 µm, tested using eddy current measurement
Result: 2016 hours of resistance
We stand for the highest corrosion protection standards—let’s work together to meet your requirements!
Give Your Components the Glow of Golden Performance!
Our refinement technology offers top physical and chemical performance—perfect for applications requiring the highest precision. Gold coatings according to ASTM G 45204C Type 1 Grade C provide corrosion and wear protection along with a refined appearance.
Your Benefits:
Durability and resistance
High purity > 99.7%
Hardness of 120-190 HV
Contact resistance
AC 46000: A Masterpiece in Surface Technology.
The Aurolia team has earned a reputation for seeing their customers' challenges as exciting opportunities, and this case was no exception. It wasn't just about creating a desired component out of AC 46000 in a decorative and appealing form. Rather, our goal was to achieve a very specific attribute associated with exceptionally high adhesion strength.
Improved Occupational Safety with a Positive Side Effect
Process Optimization Makes Hydrofluoric Acid Redundant
Sometimes, on the journey to a solution, you find much more than you expect. This was the case in a collaboration with one of our customers. They produce covers for connectors in electric vehicles using the aluminum die-casting process. In order to remove the residues typically associated with this process, the components were previously pickled with concentrated hydrofluoric acid.
Impossible to Enhance
Impossible to Enhance
A customer approached us with the request to coat the alloy AW 7075 T6511 - after several platers had already rejected the order, stating that it was not possible. The alloy in the T6511 condition contains hardenings in the edge area, which are visible as a dark edge after coating. During a hardness test of the material, a difference of over 50 Brinell between the edge and the core was found - with losses increasing proportionally as the component diameter increases. Our solution: If manufacturers provide the workpiece with some machining allowance and machine off the hardened edge, even the previously considered unsuitable for coating alloy AW7075 in the T6511 condition can be excellently and uniformly refined.

AC 46000: A Masterpiece in Surface Technology.
Das Aurolia-Team hat sich mittlerweile einen Ruf dafür erarbeitet, die Herausforderungen ihrer Kunden als spannende Gelegenheiten anzusehen, und dieser Fall war keine Ausnahme. hierbei ging es nicht einfach nur darum, ein gewünschtes Bauteil aus AC 46000 in dekorativer und ansprechender Form herzustellen.

It wasn’t just about producing a component from AC 46000 in a decorative and appealing form.

Process optimization eliminates the need for hydrofluoric acid.
Impossibly Refined
A client approached us with the request to coat the alloy AW 7075 T6511—after several plating companies had already declined, stating it wasn’t possible. The alloy, stretched in the T6511 condition, has hardened edge areas that show up as a dark fringe after coating. Hardness testing of the material revealed a difference of over 50 Brinell between the edge and the core, with percentage losses increasing as the diameter of the component grows. Our solution: If manufacturers apply a small machining allowance to the workpiece and remove the hardened edge, the alloy AW 7075 in the T6511 condition—previously considered unsuitable for coating—can be refined to a high standard with a uniform finish.

Aurolia Technologies
Your service provider for innovative and precise surface finishing with the most advanced technologies.
Our range of services extends from anodizing and hard anodizing to specialized processes like chemical nickel plating and blasting with glass or stainless steel beads.
These processes offer customized solutions for numerous industries, including the automotive industry, medical technology, and the defense industry.
Anodizing not only gives aluminum parts an attractive appearance but also increases their durability.
Whether natural or black anodizing on various aluminum alloys like EN AW 7075 or EN AW 5083—our processes guarantee high-quality, corrosion-resistant surfaces. For demanding applications, we also offer hard anodizing, which is characterized by its robustness and wear resistance, for example in shock absorbers, braking systems in the automotive industry, grippers for robotics, and much more.
In the field of blasting, we rely on modern technologies such as glass bead blasting and stainless steel bead blasting, which enable uniform and gentle surface treatment. Particularly in combination with anodizing or chemical nickel plating, we offer comprehensive protection against external influences as well as enhanced appearance and feel.
Our chemical nickel processes like Low Phos, Mid Phos, and High Phos provide excellent corrosion protection for various materials such as aluminum, steel, or copper. Chemical nickel also ensures uniform, contour-true finishing and is ideal for precision parts in medical technology and electronics.
Trust Aurolia Technologies when it comes to first-class surface treatments—from anodizing to chemical nickel plating, we offer solutions that not only give your products a premium appearance but also maximize functionality.
