discovered that heat made copper more malle-able. Casting and smelting of copper began around B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.

IACS (International Annealed Copper Standard). Alloy 25 also exhibits exceptional resistance to stress relaxation at elevated temperatures. Brush Alloy 190 is a mill hardened strip product. In other words, the strip is age hardened to a specified strength level as part of the manufacturing process at Brush Wellman prior to shipment.

Chapter 6 Copper Production Technology

The alloys are harder, stronger and tougher than pure copper. They can be made even harder by hammering them – a process called 'work hardening'. The copper alloy tree shows the options for adding other metals to make different alloys. Below are some examples. Click on the diagram above to see a larger version. Copper + tin = tin bronze ...

Copper Mining and Production Processes Explained

Feb 18, 2014· The more common leadframe materials today are copper and its alloys. While pure copper can be used, a copper alloy lead frame like copper-iron, copper-chromium, copper-nickel-silicon, or cop - per-tin, can have better hardness properties, which reduce bending and deformation during the assembly process and in more aggressive thermal cycling ...
