BRUSH WELLMAN WIRE PRODUCTS

Copper beryllium wire is used in many diverse applications including:

• Miniature machined electronic sockets
• Long travel coil springs
• Cold headed fasteners
• Spring loaded contact test probes
• Lightweight, fatigue resistant stranded cable
• Bandoliered connector contacts
• Braided shielding cloth
• Corrosion and biofouling resistant marine wire and wire mesh structures
• Eyeglass frames

Wire that is straightened and cut to length is called rod (see Rod/Bar). Wire is available with cross sections other than round, such as flat wire, used in place of narrow slit strip, and square wire, used in electronic contacts where wire wrapping requires sharp corners for reliable contact.

Brush Wellman supplies wire in diameters from 0.050” to 0.500”. Fine wire, below 0.050”, can be supplied either by special order from Brush Wellman or from any one of a number of copper beryllium wire redrawers.

Copper beryllium wire is supplied annealed (A), or in quarter hard (1/4H), half hard (1/2H), or full hard (H) tempers. In special cases, prehardened, or “pretempered” wire is available. This product offers versatility in strength and durability for products with mild to somewhat stringent forming requirements.

Leaded Nickel Copper wire is supplied annealed (A), full hard (H), annealed and aged (AT) but more typically, pretempered (HT) temper.
