Platinum tungsten alloy wire

• Platinum-tungsten alloy is a platinum alloy based on adding tungsten, it has high strength, high elasticity, corrosion resistance, oxidation resistance and other excellent properties, is commonly used in medical devices in the development material. Development, spring coil is a kind of components used in the medical device in development, it can be under X-ray clearly show the location and shape of the instrument, the convenient doctors operate and diagnosis. , developing spring coil material selection requirements of good development, biocompatibility, stable chemical and physical properties and machinability, platinum, tungsten alloy is a kind of to meet the requirements of the ideal material. , enhancement of the spring coil wire diameter generally between 0.01 mm to 0.1 mm, according to the different application scenarios and requirements, you can choose different wire diameter and shape. , enhancement of the spring coil manufacturing technology mainly includes the cold drawing, annealing, heat treatment, cutting, melt the top step of the cold drawn is the key to improve the strength and elastic spring coil. Developing spring coil has a very wide range of applications, for example, can be used to take bolt support, endoscopy, heart valve spring coil, embolism, transmission cables and other kinds of medical apparatus and instruments.
