WROUGHT
COPPER ALLOYS
The following wrought copper alloy products are available
from stock. Other copper alloys are available on a made to order basis.
Please submit your inquiry for prompt price
and delivery information.
C10100 Oxygen-Free Copper is produced by the
direct conversion of selected refined cathodes and castings under
carefully controlled conditions to prevent any contamination of the pure
oxygen-free metal during processing. The method of producing O.F.H.C.
Copper insures extra high grade of metal with a copper content of
99.99%. With so small a content of extraneous elements, the inherent
properties of elemental copper are brought forth to a high degree.
Characteristics are high ductility, high electrical and thermal
conductivity, high impact strength, good creep resistance, ease of
welding, and low volatility under high vacuum. C10100 Copper Conforms to
ASTM B187 for bar & ASTM B152 for plate.
C18200 Class II Chromium Copper is a heat treatable, corrosion
resistant alloy which combines high electrical conductivity with high
strength. Class II chrome copper is a superior resistance welding electrode
material specifically recommended for high level production spot welding and
seam welding of clean mild steels, low alloy steels, low conductivity
brasses and bronzes. Typical applications include projection welding dies,
seam welder shafts and bearings, flash and butt welding dies, resistance
welding electrodes, spot welding tips, seam welding wheels, electrode holder
jaws, cable connectors, current carrying structural members, electrical
switch gears and electrical and thermal conductors requiring greater
strength than copper.
C17510 Class III Beryllium Copper has high thermal conductivity
combined with good hardness and high temperature strength. This alloy is being
chosen with increasing frequency for applications requiring a combination of
high electrical conductivity and mechanical strength, and for applications
requiring wear and corrosion resistance. Alloy C17510 Class III beryllium copper
is specifically recommended for projection welding dies, flash and butt
welding dies, current carrying shafts and bushings. Class III alloy (having
higher strength than class II), is recommended for highly stressed welder
structural current carrying members and heavy-duty offset electrode holders.
Class III alloy is generally recommended for spot welding and seam welding
wheels having high electrical resistance, such as stainless steels.
C36000 Free-Cutting Brass is
ideally suited for high speed machining operations with its superior
machinability, thread
rolling and knurling characteristics. Its machinability rating of 100 is standard against
which all other copper alloys are rated. It is easily soldered or brazed and has good
resistance to corrosion. Typical applications included gears, pinions, plumbing ware
fittings, adapters, valves, valve stems and screw machine products. Conforms to
specification ASTM B16.
C46400 Naval Brass
provides a high degree of corrosion resistance to
seawater at even higher than normal temperatures while also assuring greater strength and
rigidity. It possesses excellent capacity for hot working and adapts well for hot forging
and pressing. This naval brass also lends itself to drawing, forming, bending and heading.
It is readily soldered, brazed and welded. Typical applications include nuts, bolts,
rivets, valve stems, pump shafts and marine hardware. Conforms to specification ASTM B21.
C51000 Phosphor Bronze alloy possess a higher yield
strength than is readily available in most cast products. Typical
applications for phosphor bronze include bearings, bushings, gears,
pinions, shafts, thrust washers and valve parts. Can be readily brazed
or soldered. Capacity for being cold worked is good. Conforms to
specification ASTM B139.
C63000 (AMS 4640) Nickel Aluminum Bronze alloy is
an excellent choice for applications involving heavy loads, adhesive
wear, friction, abrasive wear and corrosion. The addition of nickel
increases the alloys strength without diminishing its excellent
ductility, toughness and corrosion resistance. Alloy C63000 nickel
aluminum bronze has gained wide acceptance in the aircraft industry for
severe landing gear service in products such as strut bearings, main
pistons, trunnion bearings and similar vital components. Conforms to
specification ASTM B130
Many other wrought copper alloys are available from stock
or on a made to order basis. Copper alloys available include tellurium copper,
leaded commercial bronze, forging brass, architectural bronze, admiralty brass, silicon bronze, copper nickel and leaded
nickel silver alloys.
