Instrument springs pursuant to the specifications of ISO 10243, D-profile wires, color coding pursuant to spring rigidity.
All instrument springs are made of chromium steel of a high tensile strength. They can withstand large loads due to their high rigidity. Excellent mechanical characteristics even when exposed to high loads and thermal resistance of up to 230 °C. Their required mechanical characteristics are achieved by thermal modifications of the used material. That is why instrument springs can be used for a wide range of applications.
Wire profile for optimal rigidity and resistance to damage even when exposed to long-term high loads. The last thread is ground, making sure it forms the maximum possible contact surface.
