COPPER ALLOY DATA SHEET

C16200

ACB Hitenso C16200 offers a unique combination of high tensile strength and high electrical conductivity in wire for an industry where these properties are generally considered incompatible and diametrically opposed. The nominal composition of 99.0% copper and 1.0% cadmium is the reason for these properties.

The cadmium noticeably increases the copper's strength and resistance to softening and stress relaxation with minimal decrease in its electrical conductivity. It also produces an alloy noted for its malleability and toughness and spring quality

Hot Working: The hot working properties of Hitenso C16200 are considered to be good.

Cold Working: The cold working properties are excellent. The alloy may be readily drawn, rolled, blanked, stamped, and bent. The alloy work hardens somewhat more readily than pure copper and may require intermediate annealing through an extensive set of cold working operations.

Joining: Joining by soldering or brazing is excellent and can be readily done. Resistance flash butt welding is commonly practiced on redraw rod and wire, while spot and seam resistance welding is not recommended. Applications of ACB Hitenso C16200 rarely require oxyacetylene or gas shielded arc welding, but good joints can be obtained by these methods. If welding is attempted, a standard precaution should be exercised to avoid inhalation of the hazardous cadmium-bearing fumes.

Applications: Because of its good strength and wear resistance, ACB Hitenso C16200 was used for low load transmission lines in rural areas for its earliest application. Here, line loss due to the lower conductivity of this alloy was offset by the added tensile strength which required fewer poles between spans, thus lower cost per mile of line. Today, it is commonly used to make trolley wire.

Today, because of its toughness and high conductivity, Hitenso C16200 finds wide use as small gauge wire in termination equipment, spring contacts in automotive and signal relays, and in such applications as high strength transmission lines, switch gear components, heating pads, electric blanket elements, fuse clips, and tinsel used in the telephone industry.

Applicable Specifications: When so specified, ACB Hitenso C16200 will be manufactured to the latest revision of the following specifications: ASTM B9, ASTM B105 (Alloy 80), and when used as resistance electrode material, RWMA – Group A, Class 1.

Standard Forms Available: Rod, bar, wire and flat wire. For other forms, please consult Ansonia Copper & Brass, Inc.
