What are the characteristics of titanium alloy CNC machining compared to other metals?
The most common machining parts in CNC machining centers are aluminum. By oxidizing sandblasting, you can make the desired texture and the color you want. Perhaps we do not know that there is also a processing material is titanium alloy, this material has characteristics that other metals do not have, what characteristics of titanium alloy CNC processing compared to other metals?
1. The specific strength is high. The density of titanium alloy is 4.5g/cm3, which is only 60% of steel. It is commonly used in aircraft engine components, skeletons, skins, etc.
2. Good corrosion resistance, titanium alloy can work in wet weather and seawater medium. However, it has poor corrosion resistance to reducing oxygen and chromium salt media;
3. The heat intensity is high, the working temperature of the titanium alloy can reach 500 ° C, and the aluminum alloy is only about 200 ° C;
4. Large chemical activity;
5. Good low temperature performance;
6. The thermal conductivity is small and the modulus of elasticity is small;
Although titanium alloy has the above advantages, in addition, titanium alloy has some shortcomings, that is, the chill phenomenon is serious, which is not conducive to cutting, so it is necessary to attach great importance to the selection of tool materials. The suggestion of Xiaobian is to select Good red hardness, high thermal bending strength, good thermal conductivity, and poor tooling properties with titanium alloy cnc.
