Differences from Other Copper Alloys
1. Conventional copper alloys such as Beryllium Copper (BeCu), Phosphor Bronze,
     Nickel-Silver, Bronze and Brass have following problems:

     (a) Stress Corrosion Crack (b) Degradation (c) Decline of Spring Effect (d) Low Electric Conductivity (approx. 8~20%)
     But CFA has solved above problems..

2. CFA has high strength and high electric conductivity.
     Example: CFA 90 (Cu 90%, Fe 10%): Tensile Strength 1000N/mm2 Conductivity 60% or more.

3. Wear Resistance
    More excellent than conventional copper alloys.

4. CFA has great thermal conductivity and hardness, so optimal for Soldering Iron Tip.
    CFA also has thermal conductivity characteristics most required in Molding material.

5. CFA, not like other copper alloys, has magnetic forces,
    and shows excellent performance in shielding Electromagnetic Waves.

     (Results of comparative performance test with the products commonly used in the world-class
      companies have been announced, and CFA is also recognized in the economic efficiency.)

6. Iron and Copper are materials abundant in the earth, and the recycling of alloys does
     not produce hazardous substances; also safe on the issue of pollution.


7. In welding of copper alloys and welding of dissimilar metals, there have been
     difficulties, however, now it is easily done with CFA Welding Wire.


8. RoHS Regulation
    Most of conventional copper alloys use such hazardous substances as lead(Pb) etc.
    but CFA is a complete two-element alloy (Copper+Iron) that serves reduction of
    manufacturing costs and helps solve environmental problems.
