Magnesium aluminum square tube level ruler

Magnesium aluminum square tube level ruler is a lightweight and high-precision measuring tool used in mechanical manufacturing and precision testing to measure flatness and straightness. It is made of high-quality magnesium aluminum alloy (such as 6061-T6) as the core material, and is extruded, aged, and precision ground. It has significant advantages of lightweight and high strength, and weighs only 1/3-1/2 of the same specification cast iron level ruler, making it easy for operators to handle and use.

Its structure is in the shape of a hollow square cylinder, which reduces weight while ensuring overall rigidity through reasonable wall thickness distribution (usually 5-10mm), avoiding bending deformation caused by stress. The working surface has undergone precision grinding treatment, and the flatness error can be controlled within 0.01mm/m. The straightness accuracy reaches 0.02mm/1000mm, and the surface roughness is as low as Ra0.4 μ m. It can be used as a reference surface to accurately detect the plane deviation of workpieces. The two ends of the square tube are designed with anti slip end caps, and some models are also equipped with handheld grooves to further enhance operational convenience.

Magnesium aluminum alloy material has excellent corrosion resistance and oxidation resistance, and does not require frequent oil coating and maintenance like cast iron rulers. It also has a small coefficient of thermal expansion and can maintain stable accuracy in environments with large temperature changes. Compared to traditional cast iron rulers, magnesium aluminum square tube rulers are not only easy to carry, but also reduce accuracy loss caused by collisions and have a longer service life.

This ruler is widely used in machine tool manufacturing, mold processing, instrument assembly and other fields. It can be used to inspect the flatness of workbenches and guide rails, and can also be used with tools such as dial gauges to measure straightness. It is an ideal tool for improving precision machining and detection efficiency.
