BRASS - COPPER ZINC ALLOY - CuZn20

General Description

ELEKTRISOLA brass wire CuZn20 consists of 80% copper and 20% zinc (C24000). The product features very good mechanical properties and corrosion behavior comparable to copper. The low conductivity and the outstanding bending proof performance makes it the favorite choice for heating applications. Furthermore brass bare wires are suitable for electric discharge removal of material (spark erosion). Copper zinc alloy wires are available with all insulation and self-bonding enamel types as well as bare wires or litz wires.

Features

  • Very good mechanical properties
  • Outstanding bending proof performance
  • Low conductivity

Applications

  • Resistance wires
  • Heating applications
  • Spark erosion
