1) Diameter: 0.10 - 4.00mm
2) It is mainly used as conductor under high-frequency in coaxial cable taking the
place of pure copper wire
3) It is divided into soft state (A kind) and hard state (H kind) 
4) It is divided into 10% and 15% two kinds according to volumetric scale of copper
layer
5) The DC resistivity at temperature of 20°C is less than 0.02676Ω.mm²/m
6) Its nominal density is 3.32g/cm³ - 3.63g/cm³, it is 37 - 40% of pure
copper wire
7) Under the same weight, its length is 2.5 - 2.7 times that of pure copper wire
8) Its surface is bright and smooth, no any defects
9) It can save a lot of copper resource
10) Its conductivity is good
11) It can reduce the production cost of the cable and it is convenient in construction
12) It has remarkable economic benefit, besides, it is easy to be erected
13) It has good softness
14) The signal quality is centered
15) It has good ability of preventing troubles and the signal is clear 
16) It has become the most common wire used in CATV and other high-frequency conduct
cable
17) It is a bimetallic wire with a copper cladding concentrically covering an aluminum
core, integrating the beneficial properties of the wonderful conductivity
of copper and the light-weight of aluminum
18) It can be scientifically processed into bare wire and flat wire, and it is the
best material for coaxial cable, computer cable, telephone cable and shielding
cable
19) The processing method is similar to that of copper wire during cable manufacture
