Chromium CopperOverview

Chromium copper alloys are high copper alloys, containing 0.6 to 1.2% Cr. The chromium copper alloys are used for their high strength, corrosion resistance and electrical conductivity. The chromium copper alloys are age hardenable, which, in this case, means that a change in properties occurs at elevated temperature due to the precipitation of chromium out of the solid solution. The strength of fully aged chromium copper is nearly twice that of pure copper and its conductivity remains high at 85% IACS, or 85% that of pure copper. These high strength alloys retain their strength at elevated temperatures. The corrosion resistance of chromium copper alloys is better than that of pure copper because chromium improves the chemical properties of the protective oxide film. Chromium copper has excellent cold formability and good hot workability. It is used in applications such as resistance welding electrodes, seam welding wheels, switch gears, cable connectors, circuit breaker parts, molds, spot welding tips, and electrical and thermal conductors that require strength. Chromium copper alloys are designated as UNS C18050 through C18600, the cast alloys are C81400 through C81540.

The age hardening reaction occurs because the solid solubility of chromium in copper decreases as the temperature decreases. The structure of slow cooled chromium copper is a two phase mixture of chromium and alpha copper. Superior mechanical properties are achieved by fast-cooling the chromium copper alloys from the annealing temperature, so the chromium remains in a supersaturated solid solution with the copper. Followed by an aging treatment where the chromium precipitates from the solid solution forming a very fine dispersion of precipitates in the matrix. The microstructure of a quenched or quickly cooled chromium copper alloy appears similar to that of the unalloyed copper. A fast cool prevents the chromium from precipitating out of the solid solution, so the resulting cast structure consists of a single phase alpha copper structure. The first material to solidify is pure copper, followed by a eutectic mixture of alpha and chromium. The alpha and chromium eutectic material forms a lamellar structure in the interdendritic regions. The microstructure of the wrought alloy consists of equiaxed, twinned grains of alpha copper solid solution. Typically the allow are cooled rapidly so the chromium remains in alpha copper solid solution. The tempering treatment allows the chromium to precipitate out of solution forming a dispersion of chromium precipitates throughout the matrix. The chromium precipitates, or hardening precipitates, can be very fine and may not be visible at low magnifications.

C46400 Naval Brass "Lead Free"

Naval Brass C46400 is nominally composed of 60% copper, 39.2% zinc and 0.8% tin. As is typical of brass alloys with the duplex alpha beta structure, C46400 has good strength and rigidity. By substituting tin for an equal quantity of zinc, a high corrosion resistance to seawater is achieved. The addition of tin also gives the alloy an inherent resistance to dezincification, thereby further inhibiting the impingement by seawater at higher than normal temperatures. The alloy is also noted for its resistance to wear, fatigue, galling, and stress corrosion cracking.

Typical Uses for C46400 Naval Brass "Lead Free":

BUILDERS HARDWARE:Lock Pins

ELECTRICAL: Precision Shipboard Equipment

FASTENERS: Rivets, Bolts, Nuts

INDUSTRIAL: Welding Rod, Condenser Plates, Structural Uses, Valve Stems, Balls, Heat Exchanger Tube, Aircraft Turn Buckle Barrels, Bearings, Dies, Golf Ball Production, Pressure Vessels, Bearings, Bushings, Hub Cones

Tellurium Copper
Ask Latest Price

GRADE: ASTM B301, C14500

Description: C14500 Tellurium copper round rod. C145 Tellurium is adapted for use in high-speed automatic screw machines. The copper telluride precipitations become finely dispersed throughout the matrix and assist in chip breakage into short pieces, thus enabling a much higher machining speed than with pure copper. Copper 145 Tellurium has a machinability rating scale of 85%, compared to pure copper of 20%, thus insuring longer tool life. The high conductivity of tellurium copper makes it a suitable material for electrical applications, and is an outstanding alloy for the production of hot forged products.

Applications:

  • Transistor Bases, Motor Parts, Electrical Connectors, Switch Parts, Welding Torch Tips, Soldering Tips, Screw Machine Products, Forgings , Plumbing Fittings, Sprinkler Heads, Fixtures, EDM Anodes, Tool Making Parts, Dies /Welding Torch tips / Transformer & Circuit-breaker terminals

Lead-free a + b brass with good hot forming but limited cold forming characteristics. It is particularly suited for
forging. It is significantly harder than brasses with lower zinc content. The alloy is relatively brittle, which improves its
machinability. In some cases one observes Zn-lean zones and a susceptibility to stress-corrosion cracking.
This alloy is often used in construction.

Fabrication characteristics
Sheets, ribbons, wires, profiles, tubes, dimensions and tolerances on request.
State
Welding, brazing and soldering
Available products
Poor cold formability, but excellent hot formability (625°C - 800°C). The alloy is not suitable for stamping or deep drawing. For these operations, a
brass of lower zinc content is recommended. Polishing quality is good..
Annealing in air requires subsequent pickling to remove the surface oxide layer. Annealing can also be done in a neutral (Argon) or reducing (cracked
ammoniac, N2 + H2) atmosphere. The most
performant microstructures and mechanical properties are achieved with annealing temperatures to the lower bound of the temperature interval given
above. Machining is average. Machinability
is estimated at 40% on a scale with the free cutting brass CuZn35.5Pb3 at 100%.
