Brass vs Rubber Spiral Springs | Comparison & Applications #2117735 (License: Personal Use)

The image displays two identical-form spiral springs differing only in material: a metallic brass spring with a polished golden finish and a flexible black rubber-coated spring with a matte surface. Both feature tightly wound coils ending in a U-shaped terminal for mounting or tensioning. These springs are commonly used in automotive, HVAC, and appliance mechanisms where controlled elasticity and corrosion resistance matter.
