NedZink NOVA

Quality

NedZink produces titanium zinc according to EN 988, an alloy based on electrolytically cleaned zinc with a purity of min. 99.995 % Zn (Z1 according to EN 1179) with small additions of the alloy elements copper, titanium and aluminium.

The chemical composition, the mechanical and physical properties and measurement tolerances are determined in the KOMO product certificate and the product certificate from Lloyd’s Register, Industrial Quality Scheme for Product Certification by Surveillance of Quality Systems (approval No. QIS 122).

Compliance with the set material properties is checked at regular intervals (several times a year) by an independent and neutral control body, Lloyd’s Register.
