1 The copper-clad invar sheet material prepared by use of said method has the low coefficient of expansion, good radiating capability, large capacitance and good electromagnetic screening effect.

2 The application of copper-clad steel wire in future was also described.

3 The types, performance and applied field of copper-clad steel wires were introduced.

4 Characteristics as well as the production of copper-clad steel wire were described.

5 The processing and properties of copper-clad steel wire produced by pipe - weld cladding technique were studied.

6 This product is suitable for copper stranded and copper-clad steel wire.

7 Therefore, the advantages and test methods of copper-clad aluminum wire, and its applications in cables are described in detail.

8 The utility model relates to an epoxy paper glass cloth double-faced copper-clad plate, which is applied to the basic materials of different electronic devices, instruments and circuit boards.

9 Said invention uses the electroplating method to prepare the thin copper-clad invar sheet material.

10 High strength PVC casing, high-quality and high-efficiency lithium manganate battery; power control board is made of aluminum-based copper-clad plate with good heat dispersion.

11 The flaxseed oil modified resin has low cost and the copper-clad panel manufactured with it has performance not lower than that of copper-clad panel manufactured with tung oil modified resin.

12 Using the above criterion, we show that there exists a optimum copper-clad thickness, which have maximum of the overall critical current density.
