ASTM B381 Sealing Titanium Bushing TA2 Grade For Engine

TA2 Grade ASTM B381 Titanium Sealing Ring

The good mechanical properties of titanium ring as a structural material are achieved by strictly controlling the appropriate impurity content and adding alloying elements. Titanium ring is an ideal material for aircraft and engine because of its high specific strength, good mechanical properties and good corrosion resistance. With the development of machining technology, titanium alloy has been widely used in the manufacture of compressor section, engine hood, exhaust device and other structural frame parts of aircraft engine in recent years. Titanium processing industry is developing fast at present, it is not only with many of the good qualities of titanium industry made a lot of love, and also have sophisticated metal plastic working skills to be able to use, which has a long history of steel and non-ferrous metals processing skills and equipment to be able to use and learn about, this makes the plasticity of titanium processing skills, able to quickly improve and sophisticated. Now titanium and titanium alloy are widely used in deep submersible, icebreaker, hydrofoil, hovercraft, minesweeper, propeller, whip antenna, seawater pipeline, condenser, heat exchanger, petroleum equipment, chemical equipment, sports equipment, automobile manufacturing, medical equipment, tools and so on. Mainly using its excellent corrosion resistance, and low density, memory, non-magnetic.

Sealing ring is a ring seal with a gap, by being pressed after the elastic and tight in the static parts of the inner hole wall sealing role.
The sealing ring is a ring seal with a gap, it is placed in the ring groove of the sleeve, the sleeve and the shaft rotate together, the sealing ring by the gap is pressed after the elastic and tight in the inner hole wall of the static parts, can play the role of sealing. Each contact surface shall be hardened and polished. The sealing ring is made of chromium resistant cast iron and can be used for sliding speed less than 100m/s. If the sliding speed is within the range of 60 ~ 80m/s, the sealing ring can also be made of tin bronze.

Main advantages and applications:

1. Low density.

2. Higher than strength.

3. Small elastic modulus;

4. High fatigue strength, suitable for spring;

5. Low coefficient of thermal expansion.

6. Good corrosion resistance.

8. Good formability.
