FEPAC can provide precious silver copper clad metals (AgCuZnNi, AgCuNi or AgPd) to domestic and overseas customers to make top grade commutators and brushes.
Clad Metals for Micromotor

Features

 » Excellent wear resistance
 » High electric conductivity
 » Good anti-oxidation ability
 » Stable contact resistance
 » Minimum metal transfer

Layer Ratio

Inside material thickness of inlay ranges from 0.04mm to 90% of the base layer; for overlay any layer ratio can be reached.

Meterial Composition

The new clad metals are specially design for commutators and brushes in DC micro motors. The materials are classified into two main alloys: AgCuZnNi or AgCuNi/TU1 (base layer) and AgPd/BZn 18-26 (base layer).


Application

Technological design features of material composition

For commutators, trace elements Zn, Ni are put into the AgCu alloy to enhance the electric conductivity, wear resistance and anti-oxidation abilities; And TU1 (base layer) is superior to common coppers regarding electric/ thermal conduction.
For brushes, AgPd alloy is unique in low contact resistance, excellent wear resistance, minimum metal transfer, etc.; And BZn18-26 (base layer) provides good anti-corrosion, wear resistance and flexibility.

Features of manufacture technology

Clad metals manufactured into long rolls ( without welding conjunction), suitable for mass pressing process;
Close tolerance to meet different applications;
Smooth surface can reach mirrored effects;
Good uniformity of alloy layers;
High bonding strength.
