The properties of the spring material determine to a large extent the physical and mechanical properties of its springs and influence the design development and specialization of torsion springs.
When selecting materials for springs, attention is paid to the hardenability of the steel. Whether the spring material section is hardened and to what extent it is hardened is of great importance for the quality of the spring.
For electrical springs that use the spring itself as a conductor or work in conditions of varying humidity, such as water vapor, copper and gold materials are used.
In acid contact with other corrosive media spring work, choose stainless steel or nickel alloy and other corrosive materials. In the spring used in the environmental media conditions, choose ordinary spring steel, made after the spring in its surface rust-proof coating or electroplating method of corrosion prevention.
In the requirement of light weight, insulation and anti-touch, rust and corrosion prevention and other special purposes of the spring, you can choose to enhance the plastic. At present, the more applicable plastic springs, epoxy resin, phenolic resin as the substrate, reinforced with glass fiber thermoset reinforced plastic GFRP. can also be used to manufacture various types of rubber single spring anti-vibration rubber. When choosing the material, we should take into account the purpose of the spring, the degree of use, the conditions of use, processing, heat treatment and economic factors. At the same time, we should also refer to the existing equipment used in the spring, select the more suitable material.
