Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile, for a wide range of applications. The extrusion process makes the most of aluminum’s unique combination of physical characteristics. For instance, its malleability allows it to be easily machined and cast. However, aluminum is one-third the density and stiffness of steel, and the resulting products offer strength and stability, particularly when alloyed with other metals.  With the growing focus toward reducing exhaust emissions, and to meet the fuel economy standards, the demand for aluminum and aluminum-extrusion has been increasing, as aluminum extrusion aids automobile manufacturers in reducing vehicle weight, while accommodating additional safety and convenience.  The extruded aluminum content in the vehicles has been continually increasing over the past few years, and the new vehicle launches over the years have validated that growth outlook.

The global titanium alloy market (henceforth, referred to as the market studied, unless specified otherwise) registered a volume of 196.39 kilo ton, in 2017. The market is expected to reach a volume of 237.75 kilo ton million by 2024, registering a CAGR of 3.28%, during the forecast period (2019-2024), (henceforth referred to as the forecast period). The growth is majorly driven, due to its excellent mechanical and physical properties and extensive usage in a wide range of industrial applications. However, the premium pricing of titanium alloys is expected to act as a restraint for the market.
