BRASS - COPPER ZINC ALLOY - CuZn37
General Description
ELEKTRISOLA brass wire CuZn37 consists of 63% copper and 37% zinc. 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.
