Titanium mill products refer to a range of titanium materials that are manufactured through various milling processes. Titanium is a lightweight and highly corrosion-resistant metal that possesses excellent strength-to-weight ratio and heat resistance, making it an ideal material for a wide range of applications in various industries such as aerospace, automotive, medical, and chemical processing. Moreover, titanium mill products include titanium bars, titanium plates, titanium sheets, titanium tubes, and titanium forgings. These products are typically produced by machining titanium ingots or billets using milling machines, which remove excess material and give the desired shape and size to the final product.

Aluminum powder is manufactured by fine-grinding aluminum metal or by converting pure molten aluminum metal into fine droplets under a compressed gas jet environment. Aluminum flakes are derived from aluminum powder by the dry ball milling process. Aluminum paste is a type of metallic pigment which is similar to other tinting pigments. It is made from aluminum powder or flakes, petroleum solvent, and lubricant.
