把铜丝轧制成薄片，然后缠绕在纤维丝上。这种结构的线材摇摆性能和抗张强度大大提高。缺点是直流电阻大，只能用于低电流传输。
Tinsel wire is a form of low voltage[1] electrical wire used when maximum mechanical flexibility is required. It is commonly found in cords used for telephones, especially the handset cords, and in headphones. Because of its extreme flexibility it is much more resistant to failing as a result of metal fatigue than ordinary stranded wire or solid wire. Tinsel wire is also used in the power cable for very small appliances such as electric shavers or clocks, where stranded cable conctors of adequate mechanical size would be too stiff. [2] "Tinsel cords" are recognized as type TPT or TST in the US and Canadian electrical codes, and are rated at 0.5 amperes.
Tinsel wire is made by wrapping several strands of thin copper foil around a textile core. Because the foil is very thin, it is extremely flexible; the extreme thinness of the foil means that the minimum bend radius imposed on the foil is many times the thickness of the foil, leading to a low probability of metal fatigue. Meanwhile, the fabric core provides high tensile strength.
Separated from the core, the indivial foils are relatively fragile, and the textile core can be damaged by high temperatures. Together, these two factors make it difficult or impractical to terminate tinsel wire by soldering ring equipment manufacture, although soldering is possible, with some difficulty, to repair a failed connection. Although soldering may be used for emergency repairs, the foil conctors tend to break at their junction with the rigid solder. Instead, crimped connections are commonly used. Usually the connector has a series of barbs that pierce the insulation of the tinsel wire, allowing the connection to be made without the need to strip the insulation off the conctor.

Copper foil(铜箔)：一种阴质性电解材料，沉淀于电路板基底层上的一层薄的、连续的金属箔，它作为PCB的 导电体。它容易粘合于绝 铜箔
缘层，接受印刷保护层，腐蚀后形成电路图样。 Copper mirror test(铜镜测试)：一种助焊剂腐蚀性测试，在玻璃板上使用一种真空沉淀薄膜。

铜箔由铜加一定比例的其它金属打制而成,铜箔一般有90箔和88箔两种,即为含铜量为90%和88%,尺寸为16*16cm 铜箔 是用途最广泛的装饰材料。如：宾馆酒店、寺院佛像、金字招牌、瓷砖马赛克、工艺品等；
