Alloy Designation Systems for Non-Ferrous Metals According to DIN 17007

---

Introduction to DIN 17007 Alloy Designation System

The DIN 17007 standard establishes a numerical system for the designation of non-ferrous metals in Germany, known as the Werkstoffnummer. This system is widely used for cataloging and identifying various non-ferrous metals and their alloys in industrial and engineering applications.

The first digit of the designation represents the broad category of metals:

• The number 2 denotes heavy metals (excluding iron).
• The number 3 indicates light (non-heavy) metals.

The following four digits, ranging from 2.0000 to 3.9999, specify the exact metal or alloy within each category.

Structure of the DIN 17007 Numerical System

The DIN 17007 numerical system is organized to provide a clear and systematic method for identifying non-ferrous metals and their alloys. Each designation consists of five digits:

• The first digit identifies the principal group (2 for heavy metals, 3 for light metals).
• The subsequent four digits define the specific metal or alloy.

This format enables precise identification and standardization across a wide range of metal materials.

Main Categories and Alloy Groups

The following sections summarize the main groups and alloy subgroups defined by the DIN 17007 system.
