0.016mm ultra fine copper wire is our advantage. Self bonding wire is a special type of enameled wrie 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 selfbonding wire may offer cost and manufacturing advantages in some winding applications as bobbins, tape, varnishing, or impregnation may be eliminated.

Selfbonding wire can be supplied with different conductor materials such as selfbonding copper clad aluminum wire, selfbonding aluminum wire etc.
