Cross-referencing between numeric and alphanumeric temper designations to DIN 17672 and DIN 17673

Abstract

This article presents comprehensive cross-reference tables between the alphanumeric and numeric temper designation systems for wrought copper alloys as described in the German standard specifications DIN 17672 and DIN 17673. These reference tables cover various forms including rods, bars, and drop forgings made from wrought copper and copper alloys. The conversion tables serve as essential references for engineers, metallurgists, and material scientists working with copper alloys in industrial applications, facilitating standardized communication across different designation systems.

Introduction to Copper Alloy Designation Systems

Standard specifications DIN 17672 and DIN 17673 establish two parallel systems for designating wrought copper alloys: an alphanumeric system and a numeric system. DIN 17672 covers rods and bars, while DIN 17673 addresses drop forgings. Understanding the relationship between these designation systems is crucial for proper material selection and specification in engineering applications.
