distributed crustal abundance of elements titanium welding wire

Strategic metals - Ti (Titanium): element symbol Ti, atomic number 22 , atomic weight 47.88 , located on the 4th cycle Ⅳ B family in the periodic table . Titanium is one of the most widely distributed crustal abundance of elements in high (6320 × 10-6) , pure titanium wire‍ accounting for 0.61% by weight of the crust ranked 9 out ; resources are second only to iron and titanium , aluminum, magnesium and columns home section 4 is an important raw material preparation slag , synthetic rutile , titanium dioxide , titanium sponge , titanium and titanium , welding rod coatings. Because titanium silvery white , with a high melting point (1727 ℃), light weight ( 4.5 ) , high mechanical strength ( 5 ) , low temperature ( ultra low temperature resistance is almost 0 ) , abrasion resistance , good ductility titanium wire ( energy use thin wall ) , easy to oxidation, reduction , and other characteristics ; titanium oxide - titania ( titanium dioxide ) , with non-toxic , good physical and chemical surgical implant titanium‍ stability ( after 1000 ℃ calcination does not melt at any acid and alkali ) , high refractive index ( 2.55 to 2.70 ) , and strong whiteness, color strength ( 1150 to 1650 ) , the hiding power (40 ~ 50g/m2), temperature resistance, and other characteristics of the powder , called "pigment the king .
