Our Products
Lihua develops, designs, manufactures, markets and distributes high purity recycled refined copper products low cost, high quality, alternatives to pure copper magnet wire.

Copper Anode
To better address the rapid growth in the market for pure copper alternative products, in July 2010, we launched the manufacturing of copper anode following the completion of our second smelter, and in October 2011, we completed efficiency enhancements on existing copper anode and copper rod smelters, which increased total refined copper capacity to 85,000 tons. Copper anode is the raw material for copper cathode, which is the fundamental building block for almost all pure copper products, and holds a wide range of potential end market uses. As a result, customer demand for copper anode has been sizeable.

Copper Rod
In March 2009, we launched the manufacturing of copper rod from our newly acquired continuous production system for fire refining, melting and rod casting. We use scrap copper as the raw material to manufacture and sell copper rods. In addition, we produce cable and copper magnet wire from copper rods. End uses for copper rod-based wire products include:

Cable used in:

 

•

Telephone drop wire and conductors

 

•

Electric utilities; transmission lines, grid wire, fence and structured grounds

 

•

Industrial drop wire, magnet wire, battery cables, automotive wiring harnesses

 

•

Electronics: radio frequency shielding


Magnet wire used in:

 

•

Electronic motors, transformers, water pumps, automobile meters, energy, industrial, commercial, and residential industries.

Copper Clad Aluminum (CCA)
CCA is an electrical conductor consisting of an outer sleeve of copper that is metallurgically bonded to a solid aluminum core. This structure is set out in the following CCA illustration:

Over the past five years, CCA has become a viable and popular alternative to pure copper wire. In comparison with solid copper wire, CCA raw material costs are generally 35% to 40% lower per ton. CCA and pure copper raw materials are purchased based on weight. Since aluminum accounts for approximately eighty six percent (86%) by volume of CCA wire, each ton of CCA wire can yield 2.5 times the length of each ton of solid copper wire. Our CCA products are a cost effective substitute for pure copper wire in a wide variety of applications such as wire and cable, consumer electronic products, white goods, automotive parts, utility applications, telecommunications, and specialty cables.

We produce CCA wire with the line diameter in the range of 0.03 mm to 0.18 mm. We produce and distribute wire in the following forms:

  • Magnet wire.  Magnet wire can be fine or super fine and is the basic building block of a wide range of motorized appliances and is mainly used for its electrical conductivity.

  • Tin plated wire.  Tin plated wire is mainly used for the transmission of audio and visual signals.

  • Raw wire.  Raw wire is sold to smaller wire manufacturers for further processing.

    We produce CCA wire in accordance with customer orders and we customize our products based on customer specifications. Customer specifications vary depending on the end use of the CCA wire, but are primarily determined based upon two measurements, the thickness of the copper layer on the aluminum core and the diameter of the CCA wire.
