The shear beam load cell is made of three different materials:
Tool steel (alloy steel)
Aluminum
stainless steel
So far, tool steel components are the most popular shear beam load cell. Compared with other materials used in the construction of the shear beam load cell, it is more cost-effective. The most popular alloy is 4330. Tool steel load cells are relatively inexpensive and have a large capacity range, making them most suitable for use in dry applications.
Aluminum is mainly used for single-point, low-volume applications. Due to the low creep and hysteresis, the selected aluminum is 2023. Among the three materials used to make load cells, aluminum is the cheapest. Aluminum load cells are limited by their low capacity range and should not be exposed to moisture or chemical conditions.
The third material used in the manufacture of the shear beam load cell is stainless steel. The stainless steel alloy used is 17-4 ph. This alloy has the best overall performance of all stainless steel derivatives. Stainless steel load cells are more expensive than tool steel or aluminum, but their corrosion resistance makes them ideal for wet or corrosive applications.
