Digital Level Features:
Lighter weight, no more than 1.5kg/m for 2 meters, 3kg/m for more than 2 meters. A 6-meter-long ruler is only 18 kilograms, which can be easily used by one person. Not easy to deform: under normal circumstances, the bending point of steel material is 30km/mm², the bending point of cast iron is 38km/mm², and the magnesium-aluminum alloy reaches 110km/mm², which is equivalent to 3-4 times, which is resistant to bending. , the effect of deformation is not easy to occur, and the bending resistance index of magnesium aluminum alloy ruler far exceeds that of other materials.
