Alloy 90 (CuNi10) Copper Nickel Resistance Wire – 0.20mm Complete Product Description
Product Overview
Alloy 90 also well known as Cuprothal 90, standard marked CuNi10, is a classic low nickel copper-nickel alloy material professionally manufactured by precise smelting, continuous casting, multi-pass cold drawing and precision stress relief annealing treatment. This alloy features rational nickel-copper ratio, outstanding electrical conductivity, stable inherent resistance characteristic, reliable mechanical ductility and excellent atmospheric corrosion resistance. Different from high nickel grade CuNi23 Alloy 180 and CuNi44 constantan, Alloy 90 owns lower resistivity and obvious positive temperature coefficient, perfectly suitable for manufacturing low resistance wire wound components, low temperature heating units and current sensing parts that require high conductivity and stable working performance under long-term running condition. The whole production process strictly follows industrial standard specifications, with uniform wire diameter, smooth and oxide-free surface, stable batch consistency, fully adapted to mass industrial production and electronic supporting application scenarios.

Core Product Advantages
1. Low Resistivity & Excellent Conductivity
Alloy 90 CuNi10 has obviously lower resistivity compared with CuNi23 Alloy180 and CuNi44 constantan, with excellent current carrying capacity. It can meet the design demand of low resistance value components, avoid too long winding length, optimize product structure and save raw material cost effectively.
2. Stable Positive Temperature Coefficient Characteristic
With steady positive TCR value, the resistance changes linearly with temperature rising, the performance is predictable and controllable. It is very suitable for temperature compensation circuit and self-temperature-limiting heating occasions, maintaining stable working state under variable ambient temperature.
3. Superior Formability & Winding Performance
After precise annealing treatment, the wire owns good softness and ductility, not easy to harden and crack during repeated bending and close winding. It is compatible with automatic winding machine production, suitable for making tiny dense winding parts, high production yield and stable processing performance.
4. Good Solderability & Assembly Adaptability
Smooth bright bare surface without oxidation, easy to tin and solder, no need for special surface treatment. It can be directly welded with copper terminals and electronic pins, firm welding spot, not easy to fall off, convenient for subsequent electronic assembly and encapsulation.
5. Outstanding Corrosion & Oxidation Resistance
Copper-nickel alloy matrix forms dense protective oxide film naturally, owning good resistance to atmospheric humidity, mild acid and alkali environment and aging performance. Long-term working indoors and ordinary industrial environment will not produce obvious resistance drift and surface corrosion, greatly extending service life.
6. Cost-Effective & Batch Stable Supply
Low nickel content rationally controls raw material cost, while maintaining comprehensive performance qualification. Batch production keeps stable chemical composition and electrical parameters, no big difference between batches, very suitable for large-scale procurement and matching use in electronic factory assembly line.
