Since 1963 Bharat Metal Corporation has experienced tremendous growth and earned a reputation as an organization stocking Quality products and maintaining transparency in dealings.
The USP of the organization is a Huge Inventory of Non Ferrous Metals like Copper , Brass, Phosphorus Bronze, Lead etc in all kinds of semi finished forms like Strips, Plates, wires, Bars, Rods, Pipes etc.
Offices and stock points in Secunderabad (Hyderabad) and Mumbai enable delivery from Ready Stock more often than not.
Specialists : ETP Grade Copper and Earthing materials. Delivery as per IS/DIN/BS specifications.
Quality Assurance : We have in-house testing facility to conduct non destructive tests on copper. The material can be tested in your presence before dispatch and even before finalization of order.
By visual inspection it is not possible to differentiate between ETP Grade Copper and Commercial/industrial Copper. Hence it is necessary to test the material for Conductivity.
Please note that Conductivity and Not Purity is the Defining Test for ETP Grade Copper
At Bharat Metal Corporation, an in-house testing facility for testing of conductivity is available and the material can be tested in presence of the Customer before dispatch.
*Your information is safe with us.
Our Specialty lies supply of ETP Copper in the manufacture of EDM Electrode because of Efficient and Effective Sparking as elucidated under
Cutting efficiency and erosion resistance is attained by high conductivity of ETP Grade Copper Electrode.
This is ensured by in-house testing facility to measure the conductivity of copper.
For Efficiency, minimum machining of electrode is essential.
This is ensured by the Huge Inventory of various sizes and shapes provided.
Huge Inventory at our end also ensures immediate dispatches cutting lead time and inventory cost to the customers.
The supply of Electrodes in cut lengths helps in controlling costs.
Consistency in Quality is ensured by testing of each and every piece for conductivity.
We also Stock Chromium Zirconium Copper and Berrilium Copper
Depending on the application there are many grades of Copper. The main application of Copper is due to its properties of Electrical Conductivity. Hence the most important aspect while choosing Copper is its Conductivity and not purity.
In the Indian Market the there are two main grades of copper available----EC grade (ETP grade) and Commercial/industrial grade.
ETP grade Copper is made out of Virgin raw material extracted from the ore itself. Whereas the commercial / industrial grade copper is made by melting scrap.
While melting of scrap, oxidation is inevitable and the conductivity ( efficiency of carrying current) is reduced drastically anywhere between 30% and 70%. This reduction in efficiency cannot be controlled.
In short Commercial Copper carries only 0.3 to 0.7 times the current that ETP Grade Copper can carry.
Thus a smaller cross-section of ETP Copper is sufficient to carry a particular ampearage of current as compared to commercial grade copper thus resulting in monetary savings.
Apart from this there is a faster Dissipation of Current in ETP Copper which is vital for Earthing, lesser heating of system and so on.Variety and a large range of sizes available in ETP Grade Copper ensures flexibility in design and Cost savings.
