From what I understand of the "annealing in air" process is to heat treat the wire in air. this may be as simple as taking a torch to unshielded copper wire. I have read that there is a pulsed method as well. Possibly simple as heating the wire by putting enough current through it to reach annealing temp. As for what annealing does for the wire is either increase the ppm of oxygen in the copper or decrease it. I'm not sure but from what i have seen on a couple sites is that the copper actually crystalizes to an extent noted on the surface of the copper.

Query, annealing in air, annealing copper in air, annealing process.

Terry,

"Softening or annealing of cold worked copper is accomplished by heating to a temperature that causes recrystallization and, if maximum softening is desired, by heating well above the recrystallization temperature to cause grain growth. Method of heating, furnace design, furnace atmosphere, and shape of work piece are important, because they affect uniformity of results, finish, and cost of annealing.

Generally, two annealed tempers are available: light anneal, which is performed at a temperature slightly above the recrystallization temperature, and soft anneal, which is performed several hundred degrees higher, at a temperature just below the point at which rapid grain growth begins.
When annealing copper that contains oxygen, the hydrogen in the atmosphere must be kept to a minimum to avoid embrittlement. For temperatures lower than about 480oC, hydrogen preferably should not exceed 1%.

The most simple method to do a copper anneal process, is the usage of a clean convection oven with an integrated HEPA filter. The oven can be used for temperatures between 100?C and 450?C. The atmosphere is inert gas (nitrogen).

By enlarging the grain size, the conductivity of the copper increases."

However, you would not want to do this yourself. Copper wire comes with an
insulating varnish on it that would be destroyed if heated to these temperatures.

What you could do is buy "soft drawn" copper wire.

Gee I'm sorry Terry, just a couple of facts and I killed the group.
