According to the requirement of wide customer our company can produce copper single wire and bared wire, etc with any specification.

 

The diameter of wire blank and its allowable deviation should be in conformity with the regulations in following list:

Diameter mm	6.0~6.35	>6.35~12.0	>12.0~19.0	>12.0~19.0	>25.0~35.0
Allow deviation	±0.5-0.25	±0.4	±0.5	±0.6	±0.8

Note: The copper wire blank should be supplied in coiled. Each coil should be one continuous piece and does not permit to weld.

Mechanical property

The mechanical property of copper wire blank should be in conformity with the regulations in following list. Hard copper wire blank after anneal should meet the requirement of elongation of hot state product with relative brand in following list.

Type	Status	Diameter m	N/mm2  D.C. resistance≥	% Rate of elongation
T1, TU1	R	6.0~35	—	40
T2,T3,TU2			—	35
TU1,TU2	Y	6.0~7.0	370	2.0
		>7.0~8.0	345	2.2
		>8.0~9.0	335	2.4
		>9.0~10.0	325	2.8
		>10.0~11.0	315	3.2
		>11.0~12.0	290	3.6

Torsion characteristic

T1, T2 and T3 brand copper wire with 6.0~22.0mm of diameter should carry out torsion test. After torsion it should not appear the defects such as wrinkle, impurity, etc. The bright metallic crack is not as the judged basis of reject.

Electric property

Type	Status	The volume resistivity should not be more than
T1,TU1	R	0.01707
T2,T3,TU2		0.01724
TU1	Y	0.01750
TU2		0.01777

 Surface quality

1,   Copper wire blank should be round and tidy, the size should be uniform.

2,   Copper wire blank surface should not exist in frilling, flash, crack, impurity and other harmful defect for use.
