POLYMEROXID® xH4®
Ultra hard
Minimal wear
Maximum corrosion protection
High dielectric strength
Standards are set elsewhere!
After more than two years of development and countless test series in our technical center, we are pleased to present xH4®. The further development of our established and widely used type H is the highest-performing hard anodized layer on the market. The focus was on maximum wear resistance with the greatest possible smoothness and was achieved by developing a completely new high-tech monomer mixed acid electrolyte while simultaneously optimizing all process-relevant parameters.
xH4® outperforms conventional hard anodized layers in the quality of its properties by up to 30%!
Because we can.
We can only achieve a consistently high quality standard by maintaining the stability of all process and bath parameters. Continuous in-house analysis of all process steps, PLC-controlled processes, a well-coordinated team and our unique plano ERP system are reflected in the highest possible quality.
We are also one of the few companies worldwide to have the IHAA Type II label for our anodized coatings!
HOW POLYMEROXIDE xH4® WORKS
With our polymer oxide coating Type xH4®, we protect aluminum, a material that is very interesting for many applications, from wear. By developing a completely new polymer oxide matrix, we have been able to fundamentally optimize practically all application-specific properties. The modified structure created by the cross-linked polymers not only offers excellent wear protection, but also increased flexural strength, improved friction values, reduced slip-stick effect and protection against cold welding.
Details:
- completely new polymer oxide matrix
- smoother layers than those of our competitors
- highest possible hardness of approx. 500 HV0.25 (7075-T6)
- protects against cold welding
- maximum abrasion resistance
- reduces the slip-stick effect
- good friction properties
We coat all common wrought alloys up to a copper content of 5%. The most suitable materials are AlZnMgCu1.5 (7075) and AlMg4.5Mn (5083).
The polymeroxid®-xH4® layer grows to 40% of its total layer thickness beyond the base area (see sketch on the left). A 50μm layer therefore means a growth of approx. 20μm (40µm on the diameter). Depending on the type of material used and the requirements, layers of 30 or 50μm are common.
Layer thicknesses <20µm are not technically practical. Two layer thickness classes have become established on the market. (30 or 50µm).
The majority of workpieces are finished with a 30µm layer.
We will be happy to explain in a consultation. why exactly less than 20µm and more than 50µm are not recommended.
The effective layer hardnesses are highly dependent on the material used. For our xH4®, they are generally above 500-520 MHV0.025 (7075 T6).
