Cold-drawn and hot pull titanium wire titanium wire processing technology and features: 1. Heat pull ???? titanium wire is first with a titanium rod head machine head pressure is small, and then pull the thicker diameter titanium rod? ? the drawing out of the aperture is smaller than about 1 mm titanium rod tapered holes, by pulling can make the original titanium rod diameter becomes smaller, by repeatedly drawing, we can achieve a very small diameter titanium wire. It simply is controlled above the recrystallization temperature after heating the titanium rods out of titanium wire drawing process called thermal pull titanium wire. ???? 2. titanium cold drawn wire drawing process carried out at room temperature, usually made of titanium. VI. Titanium wire uses: ???? military, medical, sporting goods, glasses, earrings, hair ornaments, hanging plating, welding and other industries ?? Seven: Titanium advantages: ????? 1. The non-magnetic, non-toxic . ? ??? 2. Good heat resistance (melting point 1668 ± 4 ℃, boiling point 3535 ℃), good low temperature resistance (to maintain good ductility and toughness at low temperature -196-253 ℃, avoid metal cold brittleness. ?? ??? 3. Corrosion: titanium is not corroded in water, wet chlorine, chlorite and hypochlorite solution, nitric acid, chromic acid, metal chlorides, sulfides, and organic acids.
