Alumina Nanoparticles Used by Iranian Firm to Manufacture Strong Rebar
‘Artash Composite’ company has made the rebar based on pure copper whose hardness and mechanical strength are enhanced by dispersing alumina nanoparticles.
It can be used as spot welding electrode tip and submerged arc welding electrode with low cost and prolonged lifetime.
The bars can be used for production of resistant welding electrodes, submerged arc welding tips, CO2 welding tips, and welding of pipes for oil and gas industry in a large volume.
In a relevant development in May, a technological company in Iran had also succeeded in replacing copper with nanomaterials in making welding electrodes to decrease environmental hazards.
“By using these nanomaterials instead of copper, there is no need for an acidic bath and compounds, therefore, the risk of acid evaporation in the environment will be zero,” said Mohammad Reza Afkhami, the chairman of the board of directors of the company.
“Also, in common electrodes, a lot of water is needed, and with this replacement, water consumption has reduced,” he added.
Noting that the company’s experts have made lots of efforts to replace copper with different materials to decrease costs and minimize the negative environmental impacts, Afkhami said, “We have succeeded in increasing efficiency by 50% with this new technology.”
"We have also managed to enter the European markets in the past few years and exported 24 tons of electrodes to Spain. We are currently exporting our products to neighboring countries including Georgia," he concluded.
