Gr. 5 | Ti 6 al 4 v belongs to the American standard titanium alloy, executive standard: AMS 4911 h, MIL - T - 9046 - j, ASTM B265, ASME SB265, DMS1592F, 

Gr. 5 | Ti 6 al 4 v chemical composition:

Titanium (Ti) allowance, nitrogen (N) 0.05, or less carbon (C) 0.08 or less, hydrogen (H) of 0.015 or less, iron (Fe) 0.40, or less oxygen (O) of 0.20 or less, aluminum (Al) (5.5 6.75), vanadium (V), 3.5 to 4.5

Gr. 5 | Ti 6 al 4 v physical properties:

1. Small deformation coefficient: This is a significant feature of grade 5 titanium alloy machining, and the deformation coefficient is less than or close to 1. The sliding friction path of the chip on the front tool face is greatly increased, which accelerates tool wear.

2, the cutting temperature is high: because the thermal conductivity of titanium alloy is very small (only equivalent to 45 steel 1/5 ~ 1/7), the chip and the front tool surface contact length is very short, the heat generated when cutting is not easy to come out, concentrated in the cutting zone and the cutting edge near the smaller range, the cutting temperature is very high. Under the same cutting conditions, the cutting temperature is more than twice higher than that of 45 steel.

3. Large cutting force per unit area: the main cutting force is about 20% smaller than when cutting steel. Due to the extremely short contact length between the chip and the front tool surface, the cutting force per unit contact area is greatly increased, which is easy to cause the edge collapse.

Gr. 5 | Ti 6 al 4 v mechanical properties, tensile strength, sigma b p 895 mpa, yield strength sigma b p 828 mpa sigma: elongation: delta 10% or higher.

Gr. 5 | Ti 6 al 4 v corrosion resistance: although titanium alloy is very lively, low equilibrium potential, thermodynamic corrosion tendency in the medium, but in fact in many medium is stable, such as in oxidizing, neutral and weak reducing medium is corrosion resistant. This is because titanium and oxygen have a great affinity. In the air or oxygen-containing medium, titanium surface generates a layer of dense, strong adhesion and inert oxide film, which protects the titanium matrix from corrosion. It will heal or regenerate quickly, even from mechanical wear.

Gr. 5 | Ti 6 al 4 v application areas: aerospace, oil drilling, chemical equipment, sports supplies, Marine vessels, etc.

Gr. 5 | Ti 6 al 4 v form a complete set of welding materials: ERTi - 5 titanium plate titanium silk/straight
