We offer a wide range of copper alloys such as Chromium Copper Rods / Alloys, Chromium Zirconium Copper Alloys, Beryllium Copper Alloys, Tellurium Copper Alloys and Nickel Silicon Chromium Copper Alloys. Our alloys are highly conductivity precipitated hardened copper alloys having good mechanical features as compared to pure copper. We manufacture these copper alloys in the form of electrodes, rods, bars, wheels and blocks. Different sizes of these copper alloys are available as per the client's specific requirements.

Alloys - We manufacture:

• Chromium Zirconium Copper
• Nickel Silicon Chromium Copper
• Nickel / Cobalt Beryllium Copper
• Tellurium Copper
• Zirconium Copper
• Beryllium Copper
  
  

• Electrodes
• Rods & Bars
• Wheels
• Blocks
  
  

Sizes Available:

As per the client’s specific requirements.

Chromium Zirconium Copper Alloys are normally a very high strength & high conductivity alloys, which are used in spot, seam, butt and projection welding and electrical disconnectors and mainly suitable for plain as well as coated & galvanized sheets.

Physical Properties

Density	8.9 g/cc
Thermal Conductivity :	>0.77 cal/cm.cm²/s/°C
Electrical Conductivity :	>75% IACS
Softening Temp. :	500°C

Resistance to Softening:

It is the property of a material to come back to its original hardness when it is heated to a certain Temperature range for a given time and is then cooled at room Temperature.

Hardness at high Temperature:

The hardness of an electrode material at a given Temperature (above room Temperature) is a criterion for its service life.
