What are the advantages of using nickel titanium plates in the field of energy and power?

1.Core application advantages (broken down by "characteristics+industry needs+actual value")

Shape memory effect: achieving "adaptive regulation+fast response" to adapt to the dynamic needs of the power system

Characteristic essence: Under temperature/stress triggering, it can accurately restore the preset shape, with fast response speed (millisecond level) and high reset accuracy (±0.1 °).

Industry demand matching: Energy and power equipment needs to cope with dynamic scenarios such as load fluctuations, temperature changes, and fault impacts, and require an "automatic adjustment/reset" function that does not require external force.

2. Super elasticity: anti fatigue, anti vibration, extending equipment life and reducing maintenance costs

Characteristic essence: It can withstand 8% -10% recoverable strain (traditional steel only 0.1% -0.2%), has strong resistance to vibration and impact, and has a fatigue life of 1x 10⁷ cycles (far exceeding the 1 x10⁵ cycles of ordinary metal materials).

Industry demand matching: Electrical equipment (such as wind turbines, transformers, and transmission line fittings) are exposed to outdoor environments for a long time, facing wind vibration, mechanical vibration, and temperature cycling impacts, requiring high fatigue resistance and low maintenance structural components.

3. Excellent corrosion resistance: Suitable for harsh working conditions, reducing the risk of failure in outdoor/extreme environments

Characteristic essence: A dense oxide film (TiO₂+NiO) is formed on the surface of nickel titanium alloy, which is resistant to acid, alkali, salt spray, and wet heat corrosion, with a corrosion rate only 1/10-1/5 of stainless steel.

Industry demand matching: Energy and power equipment (such as offshore wind power, coastal power grids, and chemical industrial park substations) often face harsh environments such as high humidity, salt spray, and industrial corrosion, requiring materials with strong corrosion resistance.

4. Lightweight+High Strength: Improve equipment energy efficiency and reduce installation/transportation costs

Characteristic essence: The density of nickel titanium alloy is about 6.45g/cm ³, which is only 78% of that of steel, but its tensile strength can reach 1000-1500MPa (equivalent to high-strength steel), and the strength weight ratio far exceeds that of traditional metals.

Industry demand matching: New energy equipment such as wind power and photovoltaics pursue lightweight (reducing installation difficulty and transportation costs) while ensuring structural strength; Transmission line fittings and power grid equipment need to reduce their own weight and minimize the load on supporting structures.

5. High phase change enthalpy+precise thermal response: adapted to temperature difference power generation, improving energy recovery efficiency

Characteristic essence: The reversible phase transition enthalpy of nickel titanium alloy reaches 300-400J/g (far exceeding the 100-200J/g of traditional phase change materials), and the thermal response temperature range can be accurately controlled (-50 ℃ to 150 ℃).

Industry demand matching: There is a large amount of low-temperature waste heat in the energy and power sector (such as power plant flue gas, industrial wastewater, photovoltaic panel heat dissipation), which requires efficient phase change materials to achieve waste heat recovery and power generation.

6. No magnetic interference: Suitable for precision power equipment to ensure stable operation

Characteristic essence: Nickel titanium alloy is a non-magnetic material that does not generate electromagnetic interference and is not affected by external magnetic fields.

Industry demand matching: Precision instruments in the power system, such as transformers, measuring devices, and smart sensors, need to avoid magnetic interference to ensure measurement accuracy and signal stability.
