European Standards (ENs) are documents that have been ratified by one of the three European Standardization Organizations (ESOs), CEN, CENELEC or ETSI; recognized as competent in the area of voluntary technical standardization as for the EU Regulation 1025/2012.
Naturally, elZinc® titanium zinc meets all the standards’ requirements, both for the finished strips and sheets and for the individual alloying components.
elZinc® titanium zinc comes under the EN 988 standard, which defines the general
requirements for titanium zinc strips and sheets for use in the building industry.
The alloying components are high-grade refined zinc of the highest standardized level of purity Zn 99.995 according to EN 1179, with precisely defined additions of copper and titanium. Further components, such as aluminium and other trace elements, are accurately limited and the purity of the alloy is extremely precisely monitored by regular controls. See Technical Manual for mechanical and technological values pertaining to this standard.
elZinc® titanium zinc has been optimized for use in building applications. Prerequisites for this are the rolling process, which is precisely tailored to the elZinc® alloy, and accurate temperature control during manufacture.
This means the achievement of consistent quality and of compliance with all properties.
elZinc® titanium zinc stands out due to
• very good work-ability irrespective of the direction of rolling
• high creep strength (creep strain limit)
• low cold brittleness
• high re-crystallization threshold, i.e. no grain growth until 300°C;
this is crucial for soldering.
