Features:
The set contains 2 different sizes of springs. Because springs of different sizes have different elasticity and usage, giving you more choice and space for use.
Spring ends are closed and ground flat (squared) for efficient force transfer and reduced possibility of tangling.
All use alloy spring steel, with good elasticity, high precision, small installation volume and large force. Provides good mechanical properties with higher corrosion and heat resistance than music wire.
Uniform spacing, prominent curve, stable force, high plasticity and full elasticity.
Compression spring wire springs are used in everything from household appliances to electrical equipment, motors and more. As it is the type of spring required. By the load acting on them or their ends being compressed, the compression spring is compressed by the wire design trying to return the spring back to its original shape, thus the load is pushed back.
