Precision copper and copper base alloys play a major roll in electronic and automotive connectors, fasteners, closures, jewelry, coinage, medallions, musical instruments, lock hardware, plumbing goods, and decorative products. Scott Brass is pleased to provide a broad selection of brass, copper, and bronze alloys to meet your specifications.

Alloy 194 (Copper-Iron) offers a combination of greater strength than Alloy 110 (E.T.P. Copper), excellent electrical and thermal conductivity, and good fatigue strength. These combined properties are realized without the use of special heat treatments. Excellent formability allows Alloy 194 a wide range of applications: electronic lead frames, electrical contacts, terminals, connectors, fuse clips, eyelets, cable wrap, and circuit breaker contacts.

Alloy 688 (Cobalt - Modified Aluminum Brass) -688 is designed for its high strengths, less dense and better corrosion properties than C26000. Also has excellent non-directional properties, allowing for difficult good and bad way bends compared to other Brasses, Phos Bronze or Nickel Silver alloys. Applications center around springs, clips switches, contacts, relays and draw parts.

Alloy 102 (Oxygen Free Copper) offers additional advantages over Alloy 110 to the user. The purity and absence of deoxidizers combine electrical conductivity and freedom from hydrogen embrittlement necessary for super critical applications in the electronic, electrical, and communications industries.

Alloy 110 (Electrolytic Tough Pitch Copper) is used primarily in electrical components because of its current-carrying capacity. It has excellent resistance to weather and is widely used for outside applications. Alloy 110 is also used for mechanical applications such as gaskets, cable wrap, eyelets, automotive terminals, and electronic connector components.

Alloy 122 (Phosphorous Deoxidized Copper) has better ductility than Alloy 110 and is used for deep drawing that involves severe cold work or may require heating, brazing, or welding, which would tend to embrittle tough pitch copper.

Alloy 155 (Copper & Silver) Provides moderate strength, excellent formability and thermal conductivity, with only a slight loss in electrical conductivity compared to pure copper. Uses center around electrical and heat transfer applications; light duty springs, contacts, electrodes, connectors, diaphragms and heat exchanger fins.

Alloy 210 (Gilding) and Alloy 220 (Commercial Bronze) are ideal for decorative products, jewelry, medals, medallions, hardware, thermostats, and lighting fixtures, as well as for cable wrap shielding and marine hardware.

Alloy 230 (Red Brass) and Alloy 226 (Jewelry Bronze) are used for decorative and industrial products. They are widely used for costume jewelry (Gold Tone), cosmetic cases, fountain pens, bellows, automotive terminals, and connectors.

Alloy 240 (Low Brass) is used in decorative trim applications. Its yellow gold color and tonal qualities prove advantageous for musical instruments and chime plates. The combined ductility, strength, and corrosion characteristics of this alloy allow bending, blanking, deep drawing, etching, and stamping.

Alloy 260 (Cartridge Brass) is one of the most versatile alloys. Its outstanding strength and ductility make it useful for a wide range of automotive terminal connectors, industrial hardware, ammunition, decorative items, instruments, and holloware.

Alloy 268 (Yellow Brass) is sometimes used as a cheaper alternative to Alloy 260. Typical end uses include automotive radiator cores, eyelets, fasteners, grommets, and finish hardware articles.

Alloy 280 (Muntz Metal - High Zinc Brass) Excellent hot working, it's a stronger and "springier" alloy at the expense of a moderate decrease in corrosion resistance. Applications: Springs, components of electrical switches and sockets, tubes, plumbing goods and fasteners.

Alloy 510 (Grade A Phosphor Bronze) has tin with phosphor added in small quantities as a deoxidizer. This alloy has remarkable tensile strength, ductility, fatigue and stress relaxation properties, and is resistant to corrosion. Applications include springs and electronic connectors.

Alloy 519 (Phosphor Bronze 4%) has excellent formability along with good strength, high endurance limit, electrical conductivity and resistance to stress relaxation.  These properties make it suitable for electrical applications such as connectors and flexed contact blades. 

Alloy 521 (Phosphor Bronze 8%) offers superior spring properties, which makes it suitable for applications where severe formability and functional requirements are desirable.  Its excellent corrosion resistance makes it superior to other higher strength metals such as steels.

Alloy 752 (Copper - Nickel - Zinc known as 18% Nickel Silver)
Known for its excellent capacity for being cold worked and good ductility, 752 is used where forming, drawing, spinning and stamping are to be performed. Also offers excellent brazing and solderability characteristics; silver-gray in color.
