Copper Round Bar manufacturer in India

ASTM B62 is a specification that takes into consideration several cast copper based components such as valves, fittings, bars etc. While the main chemical ingredient of the specified ASTM B62 Copper Hex Bar is copper itself, the specification also mentions several other residual elements. In the instance of the copper bars which has inclusions of other residual elements such as iron, sulfur, aluminium, antimony, phosphorus, as well as silicon. While these casting Copper Round Bars are not to be plugged, welded, repaired, or burned-in, they are to be marked. Makings are to be done on these castings in such a manner that they neither hinder the usefulness of these bars nor do they cause injury to them. With regards to the mechanical properties of the Copper Flat Bar, each cast specimen will be used to separately determined them. Grade UNS C12200 is a Phosphorus deoxidized, High Residual wrought copper alloy.

Apart from the very obvious, yet excellent property of the UNS C12200 Bright Bar, such as good ductility and good malleability, these bars have good resistance to corrosion as well. The  Deoxidization process carried out on this lightly alloyed Brass Round Bar imparts the material with improved embrittlement resistance during welding operations. Moreover, properties such as soldering and brazing the UNS C12200 is frequently rated as excellent. In addition to exhibiting great formability properties, the Copper Threaded Rod is often used in those applications which have requirements of heat and electrical conduction.

The Difference Between Copper Round Bar and Precision Ground Bar

Copper Round bar is exactly as it sounds; a long, cylindrical metal bar. Copper Round bar is available in many different diameters ranging from 1/4" up to 24".

Copper Precision Ground Bar, also known as ‘Turned Ground and Polished’ shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces. The manufacturing process is designed for extremely close tolerances for surface finish, roundness, hardness, and straightness which ensures a long service life with reduced maintenance.

Copper Precision ground bar is manufactured through induction hardening. Induction hardening is a non-contact heating process which uses electromagnetic induction to produce the required heat. The steel is placed into a strong alternating magnetic field which causes an electric current to flow through the metal, generating heat. During this process the core of the steel remains unaffected and retains its physical properties.
