Titanium is a new type of bai metal. The performance of titanium is related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. The purest titanium iodide contains no more than 0.1% dao, but its strength and plasticity are low. high. The performance of 99.5% industrial pure titanium is: density ρ=4.5g/cubic centimeter,…
