A slight difference between special-shaped spring and conventional spring is that spring itself is irregular, has bending and a large number of complex angle design, and manufacturing technology is relatively demanding, equipment is also relatively demanding, generally computer winding. Because of many winding angles and bending, the production speed is slow. Because of its complexity, the production and processing of special-shaped springs can often represent the technical level of a company.

Classification and application of special spring:

Common springs are divided into compression spring, tension spring, torsion spring and special-shaped spring.

Special-shaped spring is mainly the existence of complex spatial angle, irregular bending and so on.

Common Use of Special Spring

The adaptability of special-shaped spring is very wide, such as automobile, machinery, daily hardware products.

Common Materials for Special Springs

Stainless steel spring wire

Springs made of stainless steel are not recommended for 301, 302 or 304 stainless steel when the temperature exceeds 260 degrees Celsius (500 degrees Fahrenheit).

Material of metal chord

When the temperature exceeds 121 degrees Celsius (250 degrees Fahrenheit), it is not recommended to use a spring made of metal strings for musical instruments.

Other materials

Superalloy wire, SAE6150 Chromium-Vanadium steel, INCONEL-750, INCONEL-718, Nimonic 90, Qin steel wire 72A, 65mn, 60si2mn, 55crsi, 50crva, Monel, beryllium copper, chromium-silicon steel, Elgiloy, phosphorus bronze, galvanized Qin steel wire, etc.
