1. Product introduction

The copper-silver alloy for commutator is a copper alloy containing a trace amount of silver (Ag). The trace amount of silver can change the physical properties of pure copper, so that the material has higher resistance to softening and wear resistance while maintaining high electrical conductivity. Features.

Products are widely used in automotive, home appliances, power tools and other fields of commutator.

2. Model

According to the different silver content, there are five kinds of products: copper silver (03), copper silver (08), copper silver (10), copper silver (20), copper silver (30);

According to the processing method, the products are divided into four types: upper lead rod, extruded profile, high-precision drawing profile and drawn round bar.

3. Specifications

Extrusion profile specifications: maximum width 150 mm, minimum thickness 0.5 mm, maximum section 2000 mm2, and maximum width to thickness ratio within 20;

High-precision drawing profiles: maximum width 50 mm, minimum thickness 0.5 mm, and maximum width to thickness ratio within 20;

Pull rod specifications: Φ 2.6mm to Φ 9mm .
