Pure iron, carbon steel, stainless steel, copper, brass, aluminum, titanium, Kovar, and various alloys. Many other metals possible.
Note: We are also able to perform tests to see if a material provided by the customer is forgeable.
Range of Base Material Sizes Possible
Base wire material diameters between 0.2mm and 23mm (0.008in to 0.90 in)
Possible Part Lengths
Part lengths between 1mm (0.04in) and 1,200 mm (47.2in) are possible.
Note: Please consult with us if your part is particularly long.
Tolerances / Precision Possible
Tolerances in the μm (micrometer) range are possible.
Note: What tolerances are possible depends greatly on part geometry and material.
