Manufacturer Thin Titanium Plate Titanium Foil With ASTM B265 In
Stock
Titanium foil is a titanium plate, strip, coil or sheet with
thickness less than or equal to 0.1mm. Another measure for
measuring the thickness of titanium foil is weight per unit area,
such as g/m or oz/ Fi. A larger value indicates a greater
thickness. The width of titanium foil is cut according to the
requirements of users. However, the wider the manufacturing, the
higher the productivity. The length of the roll determines the
maximum width of rolled foil. The wider, thinner and harder the
foil, the harder it is. The maximum width of rolled titanium foil
is about 600mm. Titanium and alloy foil are mainly used in
electronics, aerospace, instrumentation and other departments
Product feacture
Titanium foil is mainly used in aerospace, navigation, nuclear power, electronics, chemical
industry, petroleum, precision manufacturing, medical and
pharmaceutical industries.
Titanium has six major characteristics:
1. High strength: The strength/density ratio of titanium is better
than that of other metals, so titanium can be made into components
with high strength, good rigidity and light weight. Titanium is
used in aircraft engines, frames, skins, fasteners and landing
gear.
2. Anticorrosion: compared with stainless steel, titanium alloy has
better corrosion effect in humid air and sea water. Titanium has
great resistance to spot corrosion, acid corrosion and stress
corrosion. Titanium is resistant to alkali, chloride, chlorinated
organic matter, sulfuric acid, nitric acid corrosion.
3. High temperature resistance: the application temperature of
titanium is higher than aluminum alloy. Titanium can operate for a
long time at 450-500℃. Titanium alloy STIl has high strength at
operating temperatures of 150-500℃. Titanium can work at 500℃.
4. Low temperature resistance: working at low temperature or
ultra-low temperature, titanium alloy still has its mechanical
properties. Titanium alloy with low temperature resistance and very
low clearance still has good ductility, so titanium alloy is a good
low temperature structural material.
5. Environmental protection metal: the thermal conductivity of
titanium is lower than carbon steel or copper, but titanium has a
very good corrosion resistance, therefore, the thickness of
titanium can be greatly reduced, and the heat exchange mode is the
drop by drop condensation between titanium and steam. This mode
reduces heat transfer resistance and does not scale on the titanium
surface, resulting in better thermal conductivity of titanium.
6. Good thermal conductivity: Titanium is a non-magnetic metal,
which can not be magnetized in a large magnetic field. Moreover,
titanium is non-toxic and compatible with blood, so titanium has
been applied in the medical field.
Production way :
Rolling:
The most widely used manufacturing method of titanium foil is flat
roll strip rolling, which has high productivity, large scale and
output. The basic use of six high cold rolling mill or 20 high cold
rolling mill for production.
Heat treatment:
There are two main heat treatment methods for titanium strip foil:
vacuum annealing and continuous online protective annealing. Vacuum
annealing is to place rolls or sheets of titanium foil in a vacuum
furnace for heat treatment. Continuous online protective annealing
of Titanium strip foil is a new technology introduced in recent
years. Compared with vacuum annealing, it has higher production
efficiency and higher quality of products, but the equipment
threshold is higher, especially for the quality of products and
mechanical properties of titanium strip foil.
