Cross-reference tables for DIN aluminium wrought alloys: Part One

Cross-reference tables between alphanumeric and numeric temper designations for wrought aluminum alloys according to DIN 1788 and DIN 1790 standard specifications are given in this article. It covers sheets and strips with thickness from 0,021 to 0,035mm and aluminium alloy wires.

Cross-reference tables for DIN aluminium wrought alloys: Part Two

This technical guide presents comprehensive cross-reference tables mapping alphanumeric and numeric temper designations for wrought aluminum alloys according to DIN 1745, DIN 1746, and DIN 1747 standard specifications. The document focuses on three main categories: plates, sheets, and strips (thickness >0.35mm); tubes; and rods and bars.

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

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.

Designation of Carbon and Low-Alloy Steels

A designation is the specific identification of each grade, type, or class of steel by a number, letter, symbol, name, or suitable combination. Unique to a particular steel grade, type and class are terms used to classify steel products. Within the steel industry, they have very specific uses: grade is used to denote chemical composition; type is used to indicate deoxidation practice; and class is used to describe some other attribute, such as strength level or surface smoothness. This article describes basics of SAE, AISI, UNS, AMS, European and Japanese designation systems.

Designing to Codes and Standards

This article explores the fundamental importance of codes and standards in engineering design practice. Originating from the need for interchangeability and compatibility in manufacturing, these guidelines have evolved into essential tools for ensuring safety, quality, and consistency across industries. The text examines the distinctions between performance and specification codes, various types of standards from proprietary to international ones, and the processes through which they develop.

EN Numerical Designation System for Alloyed Aluminum Ingots

European standards for designation of aluminum and aluminum alloys, which is submitted to Technical Committee CEN / TC 132 “Aluminum and Aluminum Alloys”, have two basic designation systems: chemical symbol based designation system and numerical designation system. Chemical symbol based designation system is mainly the same for wrought products and castings while numerical system differs for wrought and casting products...
