Cross-referencing between numeric and alphanumeric temper designations to DIN 17672 and DIN 17673
Abstract
Standard specifications DIN 17672 and DIN 17673 describe alphanumeric and numeric temper designation systems for wrought copper alloys. In this article are given cross-reference tables between these two systems for rods, bars and drop forgings made of wrought copper and copper alloys.
