Surface technology for the fine mechanics

xH4 polymeroxid hard anodisingpolymeroxid®


After a two-year development period and numerous test series in our technical laboratory, we are delighted to be able to present xH4® to you. This further development of our well-established and widely-used Type H is the best hard anodised coating in the market. The focus was on maximum wear-resistance together with the highest-possible smoothness. This has been achieved through the development of a completely new high-tech amino mixed acid electrolyte combined with an optimization of all the relevant process parameters.

xH4® outperforms the competition in the quality of all relevant properties by as much as 30%.
