 雙金屬線
銅線是標準的電導體材料，但是卻有重量太重的缺點，鋁線較輕但卻導電性較差，鋼線抗拉強度優(yōu)異導電性卻很差，雙金屬線就是結(jié)合了以上各種材料的優(yōu)點、集優(yōu)良的導電性、較輕的重量、較高的抗拉強度為一體的新一代電導體材料。公司主要產(chǎn)品銅包鋁線和銅包鋼線，采用先進的包覆焊接制造技術(shù)，將高品質(zhì)銅帶同心地包覆在鋁桿或鋼絲等芯線的外表面，并使銅層和芯線之間形成牢固的原子間的冶金結(jié)合。使兩種不同的金屬材料結(jié)合成為不可分割的整體，可以象加工單一金屬絲那樣作拉拔和退火處理，拉拔過程中銅和鋁（鋼）同比例地變徑，銅層體積比則保持相對恒定不變。
由于高頻信號具有“趨膚效應(yīng)”的特點，因此銅包鋁線和銅包鋼線在傳輸高頻信號(大于 5 MHz) 時，具有與純銅線相同的導電性能。
銅包鋁線和銅包鋼線等雙金屬復合導線的優(yōu)點
1.獨特的復合性能：銅包鋁線同時具備銅的導電性與鋁的密度小的復合特性；而銅包鋼線則將銅的導電性與鋼的高強度結(jié)合在一起。鍍錫銅包鋼線發(fā)揮了錫的可焊性和抗硫化性；鍍銀銅包鋼線則提高了導電性、導熱性，增大了耐蝕性、抗氧化性。因而具有廣闊的應(yīng)用范圍。
2.好的延展性和可加工性：可象純銅線一樣作拉拔和退火處理，還可進一步深加工成銅包鋁漆包線，以及鍍銀、鍍錫銅包鋼線。
3.明顯的經(jīng)濟效益：銅包鋁線的密度僅為純銅線的37～40%，其長度是同等重量、同等直徑的純銅線的2.45～2.65倍；同等重量、同等直徑的銅包鋼線其抗拉強度比純銅線高1.6～2倍以上。因此，利用導線的長度或強度生產(chǎn)電線電纜，必將大大降低生產(chǎn)成本。
4.顯著的社會效益和環(huán)境效益：節(jié)省大量稀缺的銅資源；減輕電纜重量，便于運輸和網(wǎng)絡(luò)施工，減輕工人勞動強度；包覆焊接法生產(chǎn)工藝不污染環(huán)境。
BIMETALLIC WIRE
The bimetallic wire has magic performances. If combines many beneficial properties of different metals in a single wire.
Our leading bimetallic products are TTOFF CCA wire and CCS wire. By applying our ented clad-welding technique, the wire is made by fusing a core aluminum or steel wire with an external copper cladding. The two different kinds of metals are metallurgically bonded at their interface and the copper-cladding thickness remains constant, so they become a single and indissociable wire.
Because of skin effect, the AC conductivity of CCA and CCS wire equals to solid copper when frequency greater than 5 MHz.
Advantage of Bimetallic Wire
1.With composite characteristics: the bimetallic wire combines different beneficial properties in a single wire. CCA wire integrates the beneficial properties of the wonderful conductivity of copper and the light-weight of aluminum； CCS wire,carries the strength of steel with the conductivity and corrosion resistance of copper； Tinned CCS wire is good at soldering and anti-vulcanization, and Silver plated CCS wire is appreciated with excellent performance of current and heat conductivity, corrosive resistance and oxidation resistance, even in the condition of high temperature.
2.With wonderful plasticity and easy to process further: CCA/CCS wire can be done in the same way as with copper wire. CCA wire is easy to be processed to fine wire or flat wire, while CCS wire to be tinned and Silver plated.
3.Economical effect: The density of CCA is about 37～40% of that of copper, its length is 2.45～2.65 times of copper in same weight and diameter. And the tensile strength of CCS is about 1.6～2 times higher than copper. All of these contribute to reduce production cost for cable manufacturers.
4.Social and environmental effect: It is helpful to save copper resource by using copper-clad wire. The finished cable will be easy to transport and install because of light weight. And there is no pollution discharged during the production with clad-welding technique.
