Petroleum chemical instrument can be used by cable wire lashing it

Answer:

Of course, if after the aluminum cold processing (such as bending, torsion, often extrusion) will become hard, in this case you put the aluminum wire is heated to 340 degrees Celsius heat for about 5 minutes -- because aluminum wire is relatively small, so there is no need to heat too long time.
The alumina is very hard, so you think the aluminum wire is hard. You just need to dip the aluminum wire in a dilute acid for a period of time until the surface is bright.
The aluminum wire is softened without heat treatment, mainly because the surface of the aluminum wire is oxidized after a long time to form a layer of alumina,
