Copper Ingots
We are the world most reliable source for supply of high purity oxygen free copper for scientific and very sensitive applications. Our copper are purity range from 99% to 99.9999%. We work directly with manufacturers and suppliers and therefore able to negotiate the most competitive price and terms for the following products:
Copper Cathode
Oxygen Free Copper Ingot
Ultra pure copper is characterised by single crystal, unidirectional, free of impurity, flexible, fatigue-resistance, corrosive-resistance, low electric resistance, none-crystal boundaries, rapid transmissibility, perfect in structure, and easy to process.
The above characteristics make an ideal material for making rapid transmission lines.
From inner hook up wires to interconnect cables, ultra pure copper is widely applied to Hi-Tech products such as Hi-Fi stereo system, high resolution TV.
Ultra Pure Copper Ingot
Oxygen Free Copper (5N) IngotREF/CU/POLI/5N
Ingot properties:
Copper content: 99,9991% - 99,9998% (5N)
Content of detectable impurities: <0,0001 %
Ingots are absolutely free of Oxygen, Nitrogen and Carbon
Radioactivity does not exceed 1.10^-11 of degree Ci/g
The ingot has an optimal dense crystal lattice and represents a Single-Crystal
Copper is grown as crystals in complete vacuum and under high pressure patented technology.
Ingot dimensions:
Diameter: 150 mm
Height: 15 mm. - 30 mm.
Mass: 2500 gr. - 3700 gr.Copper Applications:
Single crystal copper find application in aerospace, telecommunications, high-end energy sectors and large scientific laboratories.- raw materials (foils, strips, rods, sputtering targets, substrates, powders, pastes);
- high quality wiring, cables and connectors for hifi audio and video;
- high frequency cables, connectors, switches for telecom industry;
- special duty generators and transformers;
- catalysts and chemical compounds based on crystal copper.
Packing:
Ingots are transported in special sealed containers conserved in inert gas Argon.
Net weight: 30 and 35 kg.
Gross weight: 45 and 50 kg.
Each container contains 8-10 ingots.Average weight of ingots - 3 kg
Certificate
The "Giredmet" laboratory certifies every container (minimum batch of 8-10 crystals).and individual Certificate, which states average analysis probed from eachcrystal.
