Krishna Copper Limited

Tellurium Copper C145 Tellurium is adapted for use in high-speed automatic screw machines. The copper telluride precipitations become finely dispersed throughout the matrix and assist in chip breakage into short pieces, thus enabling a much higher machining speed than with pure copper. Copper 145 Tellurium has a machinability rating scale of 85%, compared to pure copper of 20%, thus insuring longer tool life. The high conductivity of tellurium copper makes it a suitable material for electrical applications, and is an outstanding alloy for the production of hot forged products.

Rods, Ingots & Billets For Extrusion/Forging

Copper Nickel Ingots and Extruded Rods (90/10 - 70/30)” Also known as Cu-Ni, offers excellent corrosion resistance, especially in marine salt water environments. Copper nickel alloys that are generally chosen for sea water parts and service equipment contains 10 to 30 percent nickel. These various alloys also have important additions of iron and manganese, which are necessary to maintain good corrosion resistance in the harsh environments. Aside from being very corrosion resistant to sea water, copper nickel alloys are very thermally stable. Copper nickel is most commonly used in applications such as electrical and electronic products, tubes for condensers in ships and power plants, various marine products, including valves, pumps, fittings, and sheathing for ship hulls.

Available Grade:

• C70600 & C71500 / C75200/ ASTM B151, SAE J461, SAE J463

Available Forms:

• Rods, Ingots & Billets for Extrusion/Forging

Nickel silver is a metal alloy of copper with nickel and often but not always zinc. It is named for its silvery appearance, but contains no elemental silver unless plated. Other common names for this alloy are: new silver German silver, paktong, and alpacca (or alpaca). It is noted for both corrosion resistance and high electrical resistance. Our aluminum strip can be produced in standard dimensions or custom made to your requirements. We produce both imperial and metric units.

KRISCOP provides a full range of nickel silver products for almost any application. Our strip, coil, foil, bar, rod, plate, sheet, and other profiles are produced in a wide variety of alloys, including clad composites. They can be produced in standard dimensions or custom made to your requirements. Our nickel silver products are manufactured in compliance with the main international specifications, and tighter tolerances are available upon request. We offer various platings and coatings, edge conditioning, special surface conditions, profiled strip, and multiple packaging options to meet our customers requirements.
