Twisted spring, beryllium copper wire, C1720W Φ0.5, relay spring.
Beryllium copper, which has the best spring properties among copper alloys, possesses strength comparable to steel through heat treatment.
The material used is "Beryllium Copper Wire - C1720W." Beryllium copper is the material with the best spring characteristics among copper alloys. It also has good corrosion resistance and electrical conductivity, making it suitable for electronic components such as relays and connectors. Incidentally, it is known as a material for safety tools used in oil refineries and mines due to its property of not producing sparks upon impact. In its "raw" state before heat treatment, it has good workability for bending and other processes, and after heat treatment, it possesses strength comparable to steel. The heat treatment is a type of quenching known as precipitation hardening (also referred to as aging treatment), which differs from other spring materials. This product also undergoes heat treatment after spring forming to achieve the specified strength. The heat treatment temperature is 315 degrees, requiring temperature control within ±5 degrees, so a temperature-controlled batch furnace is used.
