The density of titanium coil is 4.51g/cm3, which is higher than aluminum and lower than steel, copper and nickel. Titanium melting point is 1660±10℃. Boiling point is 3287℃. Values are +2, +3 and +4. It has good corrosion resistance and is not affected by the atmosphere and seawater. At room temperature, it will not be corroded by dilute hydrochloric acid, dilute sulfuric acid, nitric acid or alkaline alkali solution; only hydrofluoric acid, hot concentrated hydrochloric acid and concentrated sulfuric acid can work.
Titanium is easily absorbed by moisture, air, grease and oxides. It not only absorbs oxygen, nitrogen, hydrogen, carbon, etc. in a dissolved state, but also some are above 400°C in the solid phase, which reduces the plastic joints and plastic joints, and causes pores and cracks. The influence of iron loss on titanium coil is mainly affected by welding, and the welding mechanical properties of the brittle titanium-iron composite phase formed by heating are reduced, and the corrosion resistance is reduced; under the action of corrosive media, the role of iron particles is pitting corrosion, and hydrogen embrittlement, etc.
