Wire Diameter
Specializing in building long-term partnerships with OEMs, Master Spring & Wire Form Co. has the expertise and latest equipment to manufacture the difficult or “impossible to make” wire forms. We have a wide range of CNC wire forming machines that can manufacture custom wire forms with diameters as small as 0.010″ or as large as 0.500″ (0.25mm to 12.7mm) and any size wire in between.
Wire Form Material Type
We manufacture custom wire forms from all types of material. The most common material types for wire forms are cold rolled steel (1008 or 1010 basic wire), stainless steel (type 302, type 304, type 316 or type 17-7 PH), music wire, hard drawn and oil tempered. You can learn about the suitable uses of each material type in our Properties of Materials chart.
