Titanium alloy material

Titanium alloy with high strength, high fracture toughness and good corrosion resistance and weldability. With the airplane increasingly composite structure, titanium materials used in the fuselage proportion will also increases day by day, because of titanium and composite performance is far superior to the combination of aluminum alloy. For example: compared with aluminium alloy, titanium alloy can make the body structure of life 60%.

High strength/titanium density than (20:1, which can reduce weight to reduce 20) of large components (it is the weight of the plane designers are the main challenges) provides solutions. In addition, the titanium alloy inherent high corrosion resistance (compared with steel can save aircraft maintenance and daily operation cost.

Need more processing ability

Because the process is more than ordinary steel, so usually think hard alloy belongs to difficult-to-machine materials. Typical of the metal removal of titanium is only the most ordinary steel or stainless steel by 25%, therefore, a titanium alloy processing time of workpiece takes approximately four times the steel processing.
In order to satisfy the aviation manufacturing titanium alloy processing of growing demand, manufacturers need to increase production capacity, so need to better understand the titanium alloy processing efficiency. Typical of the machining of titanium alloy forging, from the material removed until 80% of workpiece and final appearance.
With the rapid growth of air parts manufacturers have felt bloated, plus for processing of titanium and low efficiency of the machining, the titanium alloy processing capacity obviously in tension. Some aviation manufacturing enterprise even openly questioned whether existing machining ability finish machining of titanium alloy all new task. Because of the workpiece is usually composed of new-type alloy, so need to change the way of cutting tool materials and processing.
