The elastomers of force sensors, much like the skeleton of the human body, support the stable operation of the entire sensing system. Engineers often favor three types of metals for material selection: aluminum alloys, alloy steel, and stainless steel. Each has its own characteristics, like warriors with different personalities, performing exceptionally well on their respective battlefields.
Aluminum Alloys – Lightweight yet Tough "Scouts": With its low density and impressive strength, it acts like a nimble bird, reducing the burden on the sensor while ensuring measurement accuracy. Furthermore, aluminum alloys exhibit excellent creep and fatigue resistance, maintaining stable performance even under repeated stress tests, making it a perfect combination of lightweight and high precision.
Alloy Steel – Robust and Reliable "Heavyweight Warrior": Renowned for its high strength and superior mechanical properties, it acts like a sturdy fortress, providing solid support for the sensor. The excellent deformation consistency and recovery stiffness of alloy steel make it an ideal choice for high-load environments. Meanwhile, its weather resistance and corrosion resistance are also reliable, remaining steadfast even in the face of harsh climates or chemical corrosion.
Stainless steel-The fearless "steel guardian" against corrosion. It inherently possesses excellent corrosion resistance and high-temperature resistance, as if wearing an invisible armor, standing firm on the battlefield of humidity, acid corrosion, or high temperatures. Whether in chemical environments or high-temperature conditions, stainless steel ensures the long-term stable operation of sensors, making it synonymous with durability and reliability.
These three materials each have their own roles: aluminum alloy is lightweight and flexible, suitable for scenarios that prioritize accuracy and portability; alloy steel is strong and robust, designed specifically for high-load environments; and stainless steel, with its superior corrosion resistance, protects the long lifespan of the sensor.
