1, different titanium content: pure titanium is a silver-white metal, titanium alloy refers to a variety of alloys made of titanium and other metals gold .
2, different density: the density of titanium is 4.54g / cm3, 43% lighter than steel, higher than aluminum, but lower than steel, copper and nickel, its specific strength in the first metal. Titanium alloys usually have a density of about 4.51g/cm3, which is only 60% of that of steel. Pure titanium is a silvery-white metal with many excellent properties, such as light weight, high strength, metallic luster, and resistance to wet chlorine corrosion.
The most significant difference between pure titanium and titanium alloys is that titanium alloys are based on pure titanium with the addition of chemicals such as Al, Mo, Cr, Sn and so on, and it is precisely these chemicals that lead to the difference between these two types of titanium metals in terms of performance.
