Titanium Features

Titanium has six big characteristics:

1. High Strength: The strength / density ratio of titanium is better than other metals, which can be made of titanium having a high strength, good rigid, and lightweight components. Titanium is used in the engine, frame, skin, fasteners and landing gears.

2. Anti-corrosion: Compared with stainless steel, titanium alloy is better in humid air, and the corrosion effect in seawater is better. Titanium has a large resistance to corrosion, acid corrosion, and stress corrosion. Titanium antine, chloride, chlorinated organic matter, corrosion of sulfuric acid, nitric acid.

3. High temperature resistance: The application temperature of titanium is higher than the aluminum alloy. Titanium can be operated for a long time at 450-500 ° C. The titanium alloy STIL has a high strength at the operating temperature of 150-500 ° C. The working temperature of titanium can reach 500 ° C.

4. Low temperature: When working under low temperature or ultra-low temperature, the titanium alloy still has its mechanical properties. Titanium alloy having a low temperature resistance and extremely low gap still has good ductility, and therefore, titanium alloy is a good low temperature structural material.

5. Early metal: The thermal conductivity of titanium is lower than carbon steel or copper, but titanium has very good corrosion resistance, and therefore, the thickness of titanium can be greatly reduced, and the heat exchange mode is a drop in condensation between titanium and steam. . This model reduces heat transfer resistance, there is no fouling on the surface of titanium, so that the thermal conductivity of titanium is better.

6. Good thermal conductivity: Titanium is non-magnetic metal, not magnetized in a large magnetic field, and is non-toxic and compatible with blood, so titanium is applied in the field of medical.

How to Production Titanium Tape

Rolling:

The manufacturing method of titanium foil is the most widely rolled, and the productivity is high, large, and large. It is basically carried out using a six-roll cold rolling mill or a 20-rolling mill.

Heat treatment:

The mainstream has two types of heat treatment on the titanium tape foil: vacuum annealing and continuous online protection annealing. The vacuum annealing is to place the roll or sheet titanium foil in the vacuum furnace for heat treatment; the continuous online protection annealing of titanium belt foil is a new technology in recent years, which has higher production efficiency, and There is a higher improving product quality, but the equipment threshold is high, especially for product quality and good guarantees on the mechanical performance indicators of titanium belt foil.

Titanium Tape Application

Titanium foil is a titanium plate, strip, roll or sheet with a thickness of less than or equal to 0.1mm. Another index for assessing the thickness of titanium foil is the weight per unit area, such as g / m or oz / fi. The greater the value, the greater the thickness. The width of titanium foil is obtained by cutting according to the user′s requirements. However, the wider the manufacturing width, the higher the productivity. The length of the roll body determines the maximum width of the rolled foil. The wider, thinner and harder the rolled piece is, the harder it is to roll. The maximum width of rolled titanium foil is about 600mm. Titanium and alloy foils are mainly used in electronics, aerospace, instrumentation and other departments
