Metals Used in Medical Devices
We support most common metals and alloys used in medical device include stainless steel, cobalt-chrome alloy, titanium, and nickel-titanium alloy (nitinol). Other metals, such as gold, platinum, silver and tungsten, are also common in many medical devices.
Other wire products for the medical industry:
Special Shaped Wire
We have high quality stainless steel flat wires, square wires and shaped wires contribute to space saving and high load due to their cross-sections. Ex: SUS 304, 316L, 316 etc..
Application example: Braiding wire for catheter, Shaped wire for endoscope..

Co-Based alloy for medical use
"605PH" is an ASTM (F90 equivalent) standard material, approved as as a material use in medical applications. It provides good resistance to oxidizing environments at high temperatures for prolonged exposures and excellent corrosion resistance. Common medical applications include stents, bone drill bits, cerclage cables, guide rods, orthopedic cables and heart valves.
