Nickel Copper Alloy Tape Copper Nickel Sheet Good Welding Performance

Product Specification

Copper-Nnickel Composite Tape Sheet Coil Copper-Nickel Sheet

Product Description

Copper-nickel strip alloy is a resistance alloy with copper and nickel as the main components. It has the characteristics of good corrosion resistance, welding performance and processing performance. Its product classification and physical properties: it can be used as general resistance element, varistor, wire wound potentiometer, resistance for AC precision instrument, low temperature heating resistance (<500℃), etc. It can be used as additional resistance and shunt resistance on general electronic instruments and electricity meters. The operating temperature range is 0-100°C.

During the development process of copper-nickel strip, we independently developed advanced horizontal continuous casting technology and protective atmosphere technology, which eliminated the defects such as pores and porosity of the casting billet, and adopted new surface passivation technology to solve the problem of oxidation and discoloration of the product at high temperature of 250 °C. At the same time, the unfolded tension annealing technology is used to solve the problem of uneven performance of the strip. The comprehensive yield of the product is over 55%, ranking in the forefront of the world, and the product weight per millimeter reaches 10kg/mm

Advantages

(1) Excellent heat dissipation characteristics, significantly reducing the internal resistance of the battery by more than 10%, thereby greatly improving the safety of lithium batteries; (2) The product has excellent electrical conductivity, with a conductivity of 57% IACS, which is 2.5 times that of pure nickel;

(3) Excellent mechanical properties, which can be designed and adjusted according to customer requirements;

(4) CN-2 is a two-layer composite; NCN-2 is a three-layer composite, with copper in the middle and nickel on both sides;

(5) CN-2 has certain anti-oxidation ability after surface passivation; NCN 2 has nickel on both sides, which has strong anti-corrosion ability.

Copper-nickel composite tape. The pure mechanical composite manufacturing method is adopted, and the copper and nickel composite interface molecules are infiltrated and fused into one through a special process method without adding any medium, and a nickel-copper composite material with strong bonding force is manufactured. The copper-nickel composite tape has been greatly improved for reducing the internal resistance of the battery and prolonging the service life of the battery. As a negative electrode material, the nickel surface is the welding surface, and the copper surface is the conductive surface, which combines the advantages of nickel-plated copper tape and nickel tape to achieve the best performance of the negative electrode material.
