What materials are used for stamping spring sheets?
Release time:

Spring sheets are generally used as sensitive components, elastic supports, positioning devices, flexible connections, etc. in testing instruments or automatic devices. Different materials have different uses for leaf springs.
The spring leaf can be made of stainless steel. The spring leaf will produce large elastic deformation when loaded, which can convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original shape, which can convert the deformation energy into mechanical work or kinetic energy. The spring leaf has high elastic limit, fatigue limit, impact toughness and good heat resistance and corrosion resistance.
After heat treatment and cold drawing hardening, the 65mn spring leaf will have high strength, certain toughness and plasticity, and can be used for wear-resistant mechanical parts.
The advantage of 70# steel is that it is cheap and has convenient sources of raw materials, but its disadvantage is that it easily loses elasticity after repeated deformation and cannot work properly at 130°C. Because of the price and convenience, customers often come for the raw materials of spring sheets.
Bronze spring leaf, bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance and bright color. Excellent resilience, can be compressed up to 70% of its height, can withstand 100,000 times without deformation; strong pressure resistance, can be repeatedly compressed in both directions; fatigue resistance and durability; easy to electroplating and welding; excellent conductivity; ultra-low penetration Rate. Bronze spring sheets are often used as shielding materials for electronics.
When selecting materials for spring blades, you must consider the use, importance, load properties, size, cycle characteristics, operating temperature, surrounding media and other usage conditions of the spring blades, as well as processing, heat treatment, economy and other factors to select materials, so as to achieve twice the result with half the effort.
