5-axis milling titanium
An outstanding material demands high-performance manufacturing
Titanium is a light metal although it is 70% heavier than aluminium and only about 40% lighter than steel. However, the tensile strength of titanium (300-1,150 N/mm²) is much higher than that of aluminium (250-500 N/mm²) and almost reaches the values of steel (350-1,500 N/mm²).
Titanium is antimagnetic, which makes it completely insensitive to eddy current influences. Therefore, the material is excellently suited in the field of EMC shielding when other materials would not provide sufficient attenuation or would heat up unacceptably.
Titanium immediately forms an oxide layer when exposed to air, which protects the material from further oxidation. This layer is particularly hard and strongly adhesive - this explains the extremely high oxidation resistance to seawater, acids and alkalis.

Titanium and titanium alloys can be machined in a similar way to austenitic steels.machined. Machining by means of the various cutting processes does not pose any fundamentaldifficulties if it is taken into account that the machining
• the tool cutting edge is subjected to high thermal stress due to the relatively low specific heat,titanium's relatively low specific heat, thermal conductivity and density,
• titanium yields to the pressure of the cutting tool due to its low modulus of elasticity and high toughness properties, and
• titanium tends to weld to the tool due to the heat generated at the interface.with the tool due to the heat generated at the interface.
