1, the titanium added to the titanium- based aerospace investment castings alloy other alloying elements called titanium . Titanium has a low density , high strength , corrosion resistance , good process performance , etc., is an ideal aerospace engineering structural materials. Titanium and titanium alloy structure can be divided into heat titanium, titanium alloy , or α , β , and α + β type titanium alloy titanium alloy . Study also include forming technology of titanium alloys , powder metallurgy technology, rapid solidification technology , titanium military and civilian fields.
2 , aluminum is aluminum made by adding some alloying elements such as aluminum - manganese alloys, aluminum - copper alloys, aluminum - copper - magnesium-based hard alloy, Al - Zn - Mg - Cu based hard alloys. Aluminum has a better than aluminum physical and mechanical properties : easy processing , high durability , wide application , good decorative effect , rich color . Rust-proof titanium bicycle frames aluminum into aluminum, hard aluminum , hard aluminum and other types of various types have their own range , and have their own code , in order for users to choose.
3 , remains a lightweight aluminum features, but significantly improved mechanical properties . Application of aluminum alloy has the following three aspects : First, as the force components ; Second, as doors, windows , pipes, covers, shells and other materials ; Third, as a decorative and insulating material . After the use of aluminum anodized characteristics can be colored , made of various decorations. Aluminum alloy sheet, the surface profile can be corrosion, ginning , painting, printing and other secondary processing to produce a variety of decorative plates, profiles, as a decorative material.
