Self Solderbale enamelled Copper Wire
Normally enamelled copper conductors are used as coil components of various electrical products such as motors / transformers / home appliances / auto electrical components / chokes / AC compressors. Apart from AC compressors all other copper windings undergo secondary insulation coating and curing of the same. The process is called impregnation. The secondary insulation is used to get a firm compact winding, that can withstand vibration and all the copper conductors are held firmly together. The voids in coil are also filled by the secondary insulation. It also prevents direct contact of moisture with the primary (enamel) insulation film. The basic property of secondary insulation (varnish) is to hold the winding together. However for certain applications (where the secondary insulation is not practical) self-bonding enamelled wires can be used. These wires have an outer layer of bondable material which is usually thermoplastic and bonds the wires surfaces with each other once heated to the bonding temperature of the outer layer. Bondable wires, thus, benefits in reduction of cycle time and elimination of process of secondary insulation application / baking / curing cycle etc. APPLICATION Bondable wires can be used in power tools armature coils, electronics, miniature coils, TV yoke coils, continuous-transposed conductors etc. The bondable layer is applied over variety of primary insulation like polyester, polyester-imide, dual coated and solderable polyurethanes of class 130, 155 and 180.

Copper Strips
Commutators are electrical components for which the advantages of Tamra-oxygen-free copper can be fully exploited. Tamra-Oxygen-free copper is the purest form of the metal and offers unparalleled thermal and electrical conductivity as well as superior weldability. As a conductor, it generates much less internal heat than other copper grades and it suffers a much lower decrease in conductivity at high temperatures. A small amount of silver alloyed in copper increases the softening temperature of pure copper without any major sacrifice in electrical conductivity. Our commutator strips, profiles and wires are also manufactured in the full range of oxygen-free silver bearing copper grades. EARTHING From Transformer to Towers from IT-Building to Engineering Colleges, from Hotel to Hospitals, earthing is very important for safety of human life, equipment and functioning of an electrical system. Tamra offers strip in OFC grade and DHP grade suitable for various earthing applications. MOTOR WINDING Tamra Copper Strips is a trusted name amongst various pumps and motors manufacturing companies. Tamra Oxygen-free Copper Strips is best choice for edge winding. Tamra is a reliable name among various traction motor winding companies.

Copper Anodes
Tamra manufactures high purity copper anodes in different shapes and sizes for electrolytic copper plating. Nuggets and bar anodes are produced by a continuous casting process, while balls are produced by forging. After fabrication and sizing, the anodes are cleaned and washed so they are ready to use when they arrive. Tamra provides two grades of copper to meet the needs of most plating. The oxygen content of oxygen free anodes is controlled to less than 10ppm to provide uniform dissolution in cyanide, pyrophosphate and fluoborate baths. Phosphorised copper anodes containing 0.04-0.06 percent phosphorus are required for acid copper solutions. Nuggets are the most common form of copper anode. They are typically 1” in diameter by one-inch-long, but other sizes are available. Both OF and Phosphorus copper nuggets are available. PHOSPHORUS COPPER ANODE (DHP Gr) Tamra phosphorous copper anode with high quality plating properties, commences with supreme quality copper cathode melted with precision % of phosphorous under vigilant controlled conditions. Cast continuous rods are produced in inert atmosphere without any scope of copper's contact with air. Stage inspections are assured and monitored strictly during further process. Thus the oxygen free melt remains 0.04-0.06% consistently. APPLICATIONS Printed Circuit Boards Rotogravure Printing Cylinders ABS Plastic Coinage
