Online sources of specifications, documents and material data sheets relating to metals and manufacturing. Industry standards, Mil-Specs, OEM specs, U.S. Federal government standards, international ISO specs and more.
  1. Metal Properties

ASTM Standards for Copper and Copper Alloys
Copper and copper alloys are categorized using numbered systems. These number designations are essential to properly identifying the type, form and condition of any copper alloy. Listed below are the standard ASTM/UNS categories for copper and copper alloys.

Copper History Pt. II
Copper and bronze after the fall of Rome. Despite the development and spread of iron smelting in the 1st millennium BC putting an end to the Bronze Age, copper production grew under the supervision and guidance of Rome. Following the fall of the Roman Empire, however, copper extraction and use is believed to have dropped dramatically.

Classification of Wrought Aluminum Alloys
Classification of Wrought Aluminum Alloys. Four-digit classification is the most widely-used designation system for categorizing wrought aluminium alloys. See general categorization in the table below.
