The DIN 17007 standard defines the numerical system for designating non-ferrous metals (Werkstoffnummer) used in Germany. This system categorizes metals into major groups—heavy metals (excluding iron) and light metals—through the first digit of the designation. The next four digits specify the particular metal or alloy type within each group. This article provides an overview of the DIN 17007 alloy designation system, explains its structure, and outlines the principal alloy groups, offering a comprehensive reference for professionals working with non-ferrous metals.
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 following four digits, ranging from 2.0000 to 3.9999, specify the exact metal or alloy within each category.
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:
This format enables precise identification and standardization across a wide range of metal materials.
The following sections summarize the main groups and alloy subgroups defined by the DIN 17007 system.
This category includes pure copper, brass (CuZn alloys), bronze (CuSn, CuAl), and other copper-based alloys. It also covers various copper alloys containing elements such as nickel, zinc, aluminum, tin, lead, silver, and more.
Table 1. Copper and Copper Alloys
This group includes pure zinc, zinc alloys, zinc sheets, strips, and solders, as well as cadmium and cadmium-based alloys.
Table 2. Zinc, Cadmium, and Their Alloys
Covers pure lead and lead alloys used for cable coatings and soldering applications.
Table 3. Lead and Lead Alloys
Includes pure tin, tin-lead soft solders, die casting alloys, bearing metals, and other tin-based alloys.
Table 4. Tin and Tin Alloys
Encompasses pure nickel and cobalt, low and high alloyed Ni/Co alloys, as well as alloys containing copper, iron, chromium, and molybdenum.
Table 5. Nickel, Cobalt, and Their Alloys
Comprises pure magnesium, master alloys, and magnesium alloys with thorium, zirconium, manganese, and aluminum-zinc.
