2021 New Style Diy Cnc Machine Parts - Precision Alloy and Memory Alloy – Basile

Mechanical Automation

Including nickel-based soft magnetic alloys, nickel-based precision resistance alloys and nickel-based electrothermal alloys. The most commonly used soft magnetic alloys are permalloys containing about 80% of nickel. They have high maximum and initial permeability and low coercivity. They are important core materials in the electronics industry. The main alloying elements of nickel-based precision resistance alloys are chromium, aluminum, and copper.

This alloy has high resistivity, low temperature coefficient of resistivity and good corrosion resistance, and is used to make resistors. Nickel-based electrothermal alloy is a nickel alloy containing 20% chromium, which has good anti-oxidation and anti-corrosion properties, and can be used for a long time at a temperature of 1000-1100 °C.

Memory Alloy

Nickel alloy with 50(at)% titanium. The recovery temperature is 70°C, and the shape memory effect is good. A small change in the nickel-titanium composition ratio can change the recovery temperature within the range of 30 to 100 °C. It is mostly used in the manufacture of self-expanding structural parts used in spacecraft, self-energizing fasteners used in the aerospace industry, artificial heart motors used in biomedicine, etc.

Application field

Nickel-based alloys are used in many fields, such as:

1. Ocean: marine structures in the marine environment, seawater desalination, seawater aquaculture, seawater heat exchange, etc.

2. Environmental protection field: flue gas desulfurization device for thermal power generation, wastewater treatment, etc.

3. Energy field: atomic power generation, comprehensive utilization of coal, ocean tide power generation, etc.

4. Petrochemical field: oil refining, chemical and chemical equipment, etc.

5. Food field: salt making, soy sauce brewing, etc. In many of the above fields, ordinary stainless steel 304 is incompetent. In these special fields, special stainless steel is indispensable and irreplaceable. In recent years, with the rapid development of the economy and the continuous improvement of the level of the industrial field, more and more projects require higher-grade stainless steel. With the growth of demand for nickel-based alloys in various industries. In 2011, the scale of my country’s nickel-based alloy market reached 23.07 billion yuan, a year-on-year growth rate of 19.47%. Therefore, the development level of the industry is in a steady upward trend.

The successful development of various large-scale complete sets of equipment has made the construction of various key projects possible; the precision of machinery and equipment has driven the microelectronics industry and computer industry. The highly integrated manufacturing of integrated circuits has been realized and the capacity of the memory has been doubled; the development and production of aerospace and various weapons and equipment, the development of science and technology and education all depend on the advancement of mechanical design and manufacturing technology.

This major cultivates the basic knowledge and application ability of mechanical design and manufacturing, as well as the development of new electromechanical products.
