铜导体

: 

1.

纯铜

.

强度不够

,

只用于小功率的扬声器

; 

2.

无氧铜

(

也是纯铜

).

强度不好

,

也只用于小功率的扬声器

; 

3.

锡铜合金

.

导电率比纯铜低

,

强度中等

,

适用于中档扬声器

; 

4.

镉铜合金

.

导电性良好

,

强度大

,

适应于做大功率xx的扬声器

; 

5.

镀银镉铜

.

导电性能好

,

易于焊接

,

美观大方

; 

6.

纯银线

.

导电性能超群

,

美观大方

,

强度很好

,

但价格昂贵

Copper conductor
:
1.
Pure copper
The
Strength is not enough
,
Only for low-power speakers
;
2.
Oxygen-free copper
(
Also pure copper
).
The intensity is not good
,
Also used only for low-power speakers
;
3.
Tin-copper alloy
The
The conductivity is lower than that of pure copper
,
Moderate strength
,
Suitable for mid-range speakers
;
4.
Cadmium copper alloy
The
Good electrical conductivity
,
Strength
,
Adapted to do high-power high-end speakers
;
5.
Silver plated copper and copper
The
Conductive performance is good
,
Easy to weld
,
Nice and generous
;
6.
Pure silver thread
The
Conductive performance superior
,
Nice and generous
,
Good strength
,
But it is expensive
