Titanium alloy accelerated penetration of 3C field, industry enterprises take the lead in layout

According to relevant news, glory, Apple, Samsung and other mainstream 3C manufacturers have begun to varying degrees of import titanium alloy materials, titanium alloy is accelerating to cell phones, smart wearable, flat-panel computers, laptops and other consumer electronics products field penetration. Titanium alloy industry growth space is expected to continue to open.

Compared with traditional stainless steel, aluminum alloys and other materials, titanium can take better account of the hardness and weight of the parts, can do light and hard, better to meet the demand for thin and light 3C products.

At present, titanium alloy processing technology mainly includes CNC cutting and grinding, 3D metal printing two. Due to the material characteristics of titanium alloy, making the processing link (forming, grinding and throwing compared to aluminum alloy, the use of cutting and grinding Titanium Alloy Sheet products have a low yield, time-consuming, equipment requirements and other difficulties. To cell phone frame, for example, according to Aibang polymer data, Titanium Alloy Plate cell phone frame overall yield of about 30% -40%, much lower than 80% of the aluminum alloy frame; and processing time is long, about 3-4 times as long as the aluminum alloy. As a new direction of titanium alloy processing, metal 3D printing based on the parts of three-dimensional model of rapid manufacturing, do not need a special type of mold, the application of powdered metal materials, with the method of layer by layer printing to construct the object, high convenience, high precision, low-cost features. In addition, in the field of titanium alloy, hot isostatic pressing can effectively improve the mechanical properties of titanium alloy workpiece, reduce the cost of titanium alloy, improve production efficiency and material utilization.

It is worth noting that metal 3D printing also needs to be combined with CNC machine grinding process. Because the 3D printed parts usually have rough surfaces, additional post-processing, such as machining, grinding or polishing, in order to obtain high-precision smooth surfaces. Due to the titanium alloy material characteristics, so that the processing link (forming, grinding and polishing) value is higher, processing consumables consumption is greater. 3D printing is one of the titanium alloy forming method, began large-scale industrialization, after grinding and polishing (finishing link) value is expected to increase significantly.
