Magnesium - aluminum alloy knife - edge ruler Is a new material for manufacturing measuring tools, which is recommended by the scientific research and measurement departments of the country for the production of light-duty flat-foot and knife-edge ruler. Magnesium-aluminum knife-edge ruler has great merits, including the use of magnesium- Aluminum-magnesium flat foot, aluminum-magnesium-foot, aluminum-magnesium light-industrial-specific-foot, magnesium-aluminum parallel-foot. Al-Mg-foot in strict accordance with JB / T7977- 99 standard manufacturing. Specific performance is as follows:

1. Material: The use of super-strong aluminum alloy (aircraft skeleton aluminum), magnesium aluminum blade is not easy deformation, the general steel material of the song service point is 30kg / mm2, general cast iron pieces of the point of 38kg / mm2, the material point of service to 110kg / Mm2, cast iron flat feet and stainless steel flat feet 3-4 times, so anti-bending index far beyond the other materials.

2. Magnesium-aluminum knife-edge ruler Easy to keep, hanging flat can be, will not affect the long-term flatness of its straightness, parallelism;

3. Magnesium-aluminum knife-edge ruler Light weight, easy to use. A 6-meter magnesium-aluminum flat-foot staff can easily move, such as 2 meters, 3 meters of magnesium aluminum foot staff can be packed into precision wooden hand-held package, easy to carry out, inspection, measurement use.

4. Magnesium-aluminum knife-edge ruler Of the face with precision grinding and scraping research process, magnesium aluminum ruler for the detection, measurement, marking, equipment installation, industrial engineering construction.

5. Al-magnesium knife-edge ruler Not easy to rust: do not use oil during the period, do not use long-term, stored gently coated with a thin layer of general industrial oil can be.

6. Al-magnesium knife-edge ruler 500, 600, 750, 1000, 1500, 2000, 3000, 4000 mm.
