Good heat resistance, good weldability and excellent corrosion
resistance. The drawback is that the room temperature strength is
low. It is usually used as heat-resistant material and corrosion
resistant material. Titanium alloys are widely used in various
fields because of their high specific strength, good corrosion
resistance and high heat resistance. The industrial production of
titanium began in 1948. The demand of aviation industry makes the
titanium industry develop at an average annual growth rate of about
8%. At present, the annual output of international titanium alloy
processing materials has reached 4 million tons, and titanium alloy
trademarks are nearly 30 kinds. Titanium alloy is mainly used to
make aircraft engine compressor parts, followed by layout parts of
rockets, missiles and high-speed aircraft. In the middle of 60s,
titanium and its alloys have been used in common industries, such
as electrodes for the electrolysis industry, condensers for power
stations, petroleum refining and desalination heaters, and
environmental pollution control equipment. Titanium and its alloys
have become a corrosion resistant material.
Titanium alloy is a new important layout information used in the
aerospace industry. Its specific gravity, intensity and applied
temperature are between aluminum and steel, but it has high
specific strength and excellent seawater corrosion resistance and
ultra-low temperature function. The amount of titanium alloy in
Aeroengine usually accounts for 20% ~ 30% of the total weight of
the layout. It is mainly used to make compressor components, such
as cast titanium fan, compressor disk and blade, cast titanium
compressor casing, intermediate casing, bearing shell, etc.
Spacecraft mainly use the high specific strength, corrosion
resistance and low temperature resistance of titanium alloy to make
all kinds of pressure vessels, fuel tanks, fasteners, instrument
straps, frames and rocket shells. Artificial earth satellites,
lunar module, manned spaceships and space shuttles also use
titanium alloy plate welds.
