Work Hardening and Annealing of Copper

Experimental process 1. Prepare lengths of copper wire, 6 to 10 inches long, or tubing, 1 to 1.5 ft in length. 2. Ask selected class members to slowly bend the copper—careful not to cause crimping. 3. Once bent, ask another class member to unbend the copper. 4. Discuss why the copper cannot be fully unbent due to work hardening. 5.

Copper & steel engraving explained

Copper, being a soft metal, was easier to engrave than steel allowing the artist more freedom in the effects that could be produced. Also, being soft, the engraved lines were not as fine or hard edged as possible with steel. These two effects tended to allow a richer, warmer feel to good copper engraved prints when compared to those printed ...

Factorio Reference Sheet

For example, Iron Plate has a stack ratio of 2:1 because it takes 200 Iron Ore (2 stacks of 100) to create 200 Iron Plate (1 stack of 200) Copper Cable has a stack ratio of 1:1 because 1 stack of Copper Plate (100) turns into 1 stack of Copper Cable (200). The belt compression ratio is similar, but doesn't take stack size into account.

Alloying Elements Effects on Properties of Copper Alloys

Unalloyed copper is relatively soft compared to common structural metals. An alloy with tin added to copper is known as bronze; the resulting alloy is stronger and harder than either of the pure metals. The same is true when zinc is added to copper to form alloys known as brass. It should be noted that neither 'brass' nor 'bronze' is a concrete ...
