The term commercially pure (CP) titanium is applied to unalloyed titanium and designates several grades containing minor amounts of impurity elements, such as carbon, iron and oxygen. The amount of oxygen can be controlled at various levels to provide increased strength. Grade yang paling umum digunakan adalah grade-2. Komposisi dan sifat dari empat tingkat titanium CP tercantum di bawah ini. komposisi kimia (wt%) and minimum peralatan mekanis untuk CP titanium. Hubungi kami untuk informasi lebih lanjut.
Commercially Pure (CP) Grade 2 Titanium is one of the most common grades of unalloyed titanium. Commercially pure titanium terutama digunakan untuk ketahanan korosi.
