The Ti-6Al-4V (Ti64) alloy, also known as Titanium Grade 5, is one of the most used titanium alloys in additive manufacturing. It combines different properties like strength, lightness and corrosion resistance, making it attractive to a wide range of industries, including aerospace, automotive and medical. A major advantage of Ti64 additive manufacturing is its ability to produce customized implants for medical applications. Cutting the samples with a precision cutting machine such as the QCUT 200 A prevents the sample from overheating or being mechanically deformed during the cutting process. Mounting with an epoxy resin mounting material and using an infiltration device helps to fill all pores before grinding/polishing. Using the correct consumables during grinding/polishing can prevent smearing and makes the pore percentage measurement more accurate. This month you can find out all these important points in our preparation of the month.
