TITAN GRADE 5 ELI

Brief description

Klein designation: TITAN GRADE 5 ELI
Class of steels: 3.7165 – Titan Grade 5 ELI EN TiAl6V4 ELI / ASTM F 136
Material number: 3.7165
Standard UNS: R 56401, R 56400
RoHS 2 – 2011/65/EU:
Machinability: Cutting speed: Vc ≈ 20 – 40 m / min
Feed: 0.08 – 0.15 mm / U
Rake angle: – 100 / 120°
Lubricant-coolant: individual choice
The optimal cutting conditions depend on the machine tool, the cutting tools, the chip dimensions, the lubricant-cooling fluid, as well as the tolerances and surface the
roughness to be achieved.
Hardening capability: 950 – 955°C / up to 5 h / slow cooling to 565°C / air
Forming: warm: rough forging: 950 – 980°C, final forging: 900 – 970°C
cold: feasible, but (very) difficult
Intermediate T: intermediate temperature of 450 – 650°C can help
Cold working hardening:
Polishing ability:
Magnetism:
Corrosion resistance: The corrosion resistance of titanium Grade 4 is excellent. It can still be reinforced by the formation of a thicker TiO2 oxide layer produced by an anodic oxidation.
Uses: The Titan Grade 5 ELI is used as implant material, in the micro-mechanical engineering, and in the medical, surgical and dental fields, as well as for components for watch movements and the watch exterior. It has a good corrosion resistance in seawater and marine environment. Its resistance in chloride mediums indicates it for the chemical industry. The easiness of its anodic oxidation permits to produce a rich color spectrum of nuanced anodic oxidation colors and wear resistant oxide layers, that indicates it for jewelry, decorative and wear resistant parts.
