At California Fine Wire Co. we use precision rolling mills to provide flat wire with very tight dimensions. Our flat wire is used in a number of applications including lead ribbon, voice coil winding, and microelectronic interconnections. Ribbon wire can be produced in thicknesses between 0.0002″ and 0.050″, and in widths between 0.002″ and 0.100″. Other wire sizes may also be possible to produce, depending on the material and required dimensions. Typically, a flattening ratio of up to 40:1 can be achieved while still maintaining a minimum corner radius.
Rolling mills are designed to operate dry in order to produce wire with a clean, oil-free surface, which eliminates the need for secondary cleaning processes. However, for high purity applications, both ultrasonic cleaning and chemical cleaning processes are available.
Our consultants can assist customers regarding the availability of specific alloys and the ideal metal for their particular application. We carry numerous metal wire alloys including stainless steel, copper, and precious metals; that meet all applicable DFARS, REACH, and RoHs requirements. Quality testing, including tensile testing, dimensional inspection, and resistance testing, can be performed according to our certified procedures to verify conformance to customer specifications.
Wire can be processed in a range of production volumes for an array of applications throughout the defense, medical, aerospace, and electronics industries. Wire may be spooled or cut to length, as desired by the customer. All lead times are evaluated on a job by job basis.
