II.Titanium:Characteristic Of Titanium

Light weight With a specific gravity of 4.51, Ti is about half as heavy as copper and approximately 40% lighter than steel.
Excellent corrosion resistance (to sea water) Ti is as corrosion-resistant as platinum in seawater. This is better than any other major metals.
High strength Ti is some 6 times as strong as Al and twice as strong as Fe per weight.
Non- toxicity.Fit for the human body Safe and friendly to the human body – no metallic allergy
Non- combustibility.Heat resistance Titanium mill products have also been approved as non-combustible lic materials
Shape memory property Sensor, Motor, Thermal drive unit, Brassiere.
Hydrogen absorbing property Hydrogen car , Use of waste heat.
Cryogenic property.Superconductivity Liner motor car, Superconductive generator, MRI
Non-magnetism Electronic equipment (stepper)
Short radioactive half life Reprocessing equipment
Fashion ability Golf goods, Tennis racket, Ski, Bicycle, Mountaineering goods, Fencing mask.
Pot, Spectacle frame, Watch, Camera, Attached case, Accessories, Chinese pot.
