PROPERTIES OF ALUMINIUM
Standardisation
Appropriate standardisation is the instrument of order for all technical -scientific and personal life. It is an integral part of the economic, social and legal order.
In the course of the common European market, the national standards are gradually being replaced by the new EN standards.
In future, the national identity will only be maintained by national cover sheets - e.g. with the title DIN-EN for Germany.
For the most important semi-finished products in all business areas, alphametall has already completed this conversion. We will change offers and order confirmations accordingly after release of the corresponding standards.
We practically only see nominal changes compared to the German DIN standards. Only minor adjustments have been necessary and possible.
In the following overview, we have compared the new DIN EN standards with the previous DIN standards for your convenience:
