A special type of enamelled wire is self bonding wire. Self bonding wire is an enamelled wire with an additional adhesive enamel overcoat. This adhesive has a bonding feature, which is activated by heat or solvents. Once activated the adhesive bonds turn to turn windings into a compact self supporting coil. The use of self bonding wire may offer cost and manufacturing advantages in some winding applications as bobbins, tape, varnishing, or impregnation may be eliminated.Self bonding wire can be supplied with different conductor materials such as self bonding copper clad aluminum wire, self bonding aluminum wire etc.

FEATURES

• Low density allows coil weight reduction. only 50% weight of copper at the same length

• Easy soldering due to copper cladding

• Higher conductivity compared to aluminum

APPLICATION

• Copper Silver Alloy:High end speaker coils, audio connection wire application. Silver Content:0.1-10%

• Copper Zin Alloy: Gas nozzle, electro discharge machine, heating device. Zinc Content:10-30%

• Copper Tin Alloy: Heating components application. Tin content:0.15%-6%

• Copper Nickel Alloy: Heating components, resistance wire. Nickel content:2%-23%
