We have released many issues of knowledge about different types of bolts. Bolts are currently ubiquitous in our daily industry and have a wide range of applications, from aerospace and military industries to bicycles and electric scooters. Today, the C4-70 bolt manufacturer's editor, Ya Luo, will provide a detailed introduction to the types and commonly used application areas of bolts.
Bolts include nickel based soft magnetic alloys, nickel based resistance alloys, and nickel based electric heating alloys.
The commonly used soft magnetic alloy is BOMO alloy containing about 80% nickel. It has high magnetic permeability and initial magnetic permeability, low coercivity, and is an important iron core material in the electronics industry. The main alloying elements of nickel based resistance alloys are chromium, aluminum, and copper. This alloy has high electrical resistivity, low temperature coefficient of resistivity, and good corrosion resistance, and is used to make resistors. Nickel based electric heating alloy is a nickel alloy containing 20% chromium, which has good oxidation and corrosion resistance and can be used for a long time at temperatures of 1000-1100 ℃. Nickel alloy containing 50 (at)% titanium. Its recovery temperature is 70 ℃, and its shape memory effect is good. A small change in the nickel titanium composition ratio can cause the recovery temperature to vary within the range of 30-100 ℃. It is commonly used in automatic opening structural components for manufacturing equipment, self-excited fasteners for aerospace industry, and artificial heart motors for biomedical applications.
