Polyurethane Enameled Copper-Clad Aluminum Wire (CCA, 155/180)

Product Overview

This high-thermal-class copper-clad aluminum magnet wire pairs a metallurgically bonded copper-clad aluminium conductor with a high-temperature enamel system. It delivers the solderability and surface conductivity of copper together with a substantial reduction in conductor weight and material cost.

With thermal classes of 180, 200 and 220 and a diameter range of 0.10 to 2.00 mm, it is well suited to motor windings, automotive motors and aerospace equipment where weight reduction, thermal endurance and cost control all matter.

Key Advantages

• Dual manufacturing hubs in Changzhou and Foshan, China, covering both fine-gauge and heavy-gauge production.
• Full production range from 0.04 mm to 2.50 mm, supporting everything from micro-motors to large power equipment.
• Monthly output of approximately 3,000 tons, with stable capacity for repeat and high-volume programmes.
• ISO 9001 and ISO 14001 certified quality and environmental management systems.
• RoHS and REACH compliant insulation systems for European and North American markets.
• Wire manufactured in accordance with IEC, NEMA, GB and JIS international standards.
• High thermal class up to 220 °C combined with a lightweight conductor.
• Copper-clad surface remains directly solderable on existing lines.
• Lower conductor cost than solid copper for price-sensitive programmes.

Product Features

• High thermal shock resistance and excellent mechanical properties.
• Good wear resistance and adhesion of the enamel film.
• Continuous operation at temperatures up to 220 °C and below.
• Direct solderability with a stable, metallurgically bonded copper layer.
• Reduced conductor weight for rotating and mobile equipment.
• Consistent quality with repeatable electrical performance.

Typical Applications

• Motor windings and general rotating machines.
• Electromagnetic coils and solenoids.
• Automotive motors and auxiliary actuators.
• Aerospace and weight-sensitive equipment.
• Sealed motors operating at elevated temperature.
• Transformers and reactors where cost and weight must both be controlled.
