Characteristics of titanium and titanium alloys

Titanium is a silvery white metal, it has many excellent performance. The density of titanium was 4.54g / cm3, 43% lighter than steel, lighter than the prestigious magnesium slightly heavier. Mechanical strength of steel but with similar, more than twice as large as aluminum, magnesium than five times. Titanium, high temperature, the melting point of 1942K, higher than that of gold near 1000K, higher than that of steel nearly 500K.

Chemical properties of titanium alloy sheet are relatively active metal. Can be non-metallic effect with O2, N2, H2, S, and halogen when heated. However, at room temperature, dense titanium oxide surface protection film is easy to generate a very thin layer, can resist strong acid or aqua regia role, showing strong corrosion resistance. Thus, the general metal becomes riddled with acid, alkali, salt solution, and titanium are safe and sound.

Dissolve almost all of the liquid titanium metal, and a variety of metals can be formed alloy. Join prepared titanium steel titanium steel tough and elastic. Titanium metal Al, Sb, Be, Cr, Fe, etc. generated between interstitial compound or metal compound.

The same aircraft titanium bar for sale alloy aircraft heavier than other metals contained more than 100 passengers. Made submarines, both seawater corrosion resistance, but also anti-deep pressure, the dive depth increased by 80% compared to stainless steel submarine. Meanwhile, titanium rod for sale non-magnetic, not mine found, with good anti-guardianship role.

Vanadium has a "pro-biotic" 'sex. In the human body, can resist corrosion and non-toxic secretions, adapt to any sterilization methods. It is widely used in making medical devices, making artificial hip, knee, shoulder, threatening joints, skull, active heart valves, bone clip. When a new package in these muscles annulus "titanium-bone", these titanium bone began to maintain the body's normal activities.

Titanium is widely distributed in the body, in an amount of normal body weight not more than 70kg per 15mg, its role is unclear. But titanium can stimulate phagocytic cells, so that the immune system has been proven to enhance this effect.
