TS 5183

TS 5183 is a terminology standard that collects terms and definitions for unwrought products made from light metals and their alloys. Standards of this kind help prevent confusion between overlapping names and establish a common technical language for a material family. In this case, the focus is on naming and meaning rather than on a manufacturing process requirement.

What is meant by unwrought products?

In general technical usage, unwrought products are material forms that are not presented as finished wrought shapes such as sheet, strip, sections, bars or wire. Light metals commonly refers to low-density metals such as aluminium and magnesium, and their alloys are widely used because of their weight advantage, formability and application-dependent mechanical properties. Clear terminology is especially important where the same family of materials is handled by design, procurement and production teams.

What this standard covers

• It covers terms and definitions only.
• The scope is limited to unwrought products of light metals and their alloys.
• Its purpose is to standardise technical terminology.
• The document is identified as equivalent to ISO 3134-2:1985.

As a vocabulary standard, it is useful in specifications, materials documentation and engineering communication. Precise definitions reduce ambiguity when the same material class is described across different industries or technical documents. TS 5183 therefore serves as a reference point for consistent terminology within this specific aluminium and magnesium alloy product area.
