The right coating for aluminium surfaces
We are specialists for anodising, hard anodising, hard Ematal coating, and bond coating. We coat any aluminium surface with our 6 brands ELOX, ANOTEC®, ALTEF®, EMATEC®, EMATEF® and ANOBOND® partially or completely from 1 mm to 1.5 m or from 1 g to 120 kg since 45 years.
Coating processes
Anodising
Anodising
In conventional anodising, the surface of the aluminium component is converted into an oxide coating. This coat makes the component weather-resistant and provides decorative protection.
Hard Anodising
Hard Anodising*
In hard anodising, an advanced process converts the surface of the aluminium component into an extremely hard, thick, wear-resistant and corrosion-resistant oxide coating.
Hard Ematal coating
Hard Ematal coating*
In hard Ematal coating, the surface of the aluminium component is converted into a highly wear-resistant, corrosion-resistant oxide coating containing titanium.
Bond coating
Bond coating
In bond coating, the surface of the aluminium component is converted into a very thin oxide coating.

Passivation process
Passivation
Passivation
Through a chemical conversion process, passivation creates conversion layers that increase the corrosion resistance, stabilise the electrical contact resistance and create an ideal bond coat for paints.
Properties

hervorragend gut geringThere is only one requirement when it comes to coating: Perfection
Not all coatings are created equal. And a promise is only good if it is kept. We are particularly pleased that our name and our 6 brands are synonymous with perfection in partial coating technology and complying with specified coating tolerances. What does this mean for you? You can rest assured that your component is in the very best hands.
Altefco – Your Standard
Our approach
Thinking things through, planning ahead, working together
If you undertake a project with us, our main goal is for you to feel proud of our collaboration, which goes beyond just providing effective service. To achieve this, efficient and effective project management is a central topic. It starts with competent support and technical advice in the early stages of the project and ends with your components being optimally coated according to your requirements.
Our processes are optimised for the best possible result, so there is no idle time, no unnecessary extra costs and no loss of time that repeated prototyping could cause. The advantages of a possible partial coating are already discussed in the product development phase and tolerances are taken into account in a timely manner.
Advantages for you:
You save time and money and benefit from an all-round successful result.
Cleanrooms
On request, we can carry out the final cleaning and packaging in cleanrooms. These components leave our company packed and ready for assembly. This prevents possible contamination during transport or intermediate storage.
