ALTEF®
is very hard, wear-resistant, exceptionally slidable, smooth and easy to clean, and features many other impressive characteristics.
Link to: Anotec® DE
ANOTEC®
has a hard surface and great thermal insulation properties, is abrasion-resistant and, with special hardening, largely corrosion-resistant and exceptionally electrically insulating.
Link to: Ematef® DE
EMATEF®
allows minimal friction with outstanding sliding properties with great wear-resistance. The minimal and low-pore coating results in high dimensional accuracy and minimal roughening.
Link to: Ematec® DE
EMATEC®
is hard while also low-friction. High dimensional accuracy and minimal roughening is achieved thanks to the minimal and low-pore coating.

ANOBOND®
is the optimal adhesive primer for perfectly bonding your aluminium parts to sprayed external materials, such as plastics, elastomers and, in particular, fluoroelastomers.
Link to: Elox DE
ELOX
is decorative and offers great corrosion protection together with excellent insulation properties.

Important notes
Coating thickness
ALTEF® and ANOTEC® 15–70 µm, depending on the alloy (in individual cases even thicker); standard coating thickness for ALTEF® and ANOTEC® is 40 µm (except for EN AW-2XXX)
EMATEF® and EMATEC® 10-25 µm, depending on the alloy; ELOX 5–25 µm, as required
COATING COLOUR
ALTEF ® / ANOTEC ®
The colour of the coating depends on the alloy, coating thickness and processing. In different material compositions, shadings from light grey to charcoal grey and from bronze to dark brown are possible. For more information on the colours of the different coatings, see Alloys. ALTEF ® and ANOTEC ® can be dyed black.
ALTEF ®-GOLD / ANOTEC ®-GOLD
Due to this special process a gold-like colour is achieved. For possible alloys we announce on request.
ELOX
The coating is transparent. ELOX can be coated black: minimum coating thickness of 15µm.
EMATEF ® / EMATEC ®
The look of the coated surface is like email. The colour varies from light gray to brown-gray to bronze depending on the alloy. For more information on the colours of the different coatings, see Alloys.
ANOBOND ®
The coating is transparency and slightly iridescent. ANOBOND ® can`t be dyed.
Tolerance
Coating thickness tolerance for wrought alloys +/-5 µm (less for thinner coating thicknesses), for casting alloys +/- 10 µm
Production tolerance = pre-machining tolerance +/- coating tolerance
Pre-machining for
Example: Drilling 25H7 (0/+0,021)
ALTEF®/ANOTEC®: 40 µm coating thickness: 25+0.045/+0.056 mm EMATEF®/EMATEC®: 20 µm coating thickness: 25+0.011/+0.026 mm
ELOX: 15 µm coating thickness: 25 +0.013/+0.028 mm
